Introduction

This document must be read by personnel in charge before the assembly and the initial operation as
well as before maintenance works. Provided that the complete instruction manual in not available, the
manufacturer shall be contacted. If required, the operating company shall translate the instruction
manual to user’s language. A safe operation and and a long fatigue life can be only ensured with a
proper use of the crane.

This instruction manual is intented for the use of slewing jib cranes with booms which can only be
slewed manually.

A hoisting gear can be assembled on a crane boom solidly or with a carriage, which does not exceed,
according to data sheet, the maximum permissible values for load bearing capacity, dead weight, as
well as lifting and cross travel speed and has a rated capacity limiter. For reasons of steadiness, the
crane can not lift from the floor, according to data sheet, more than 1.4 times the lifting capacity of the
crane. During the operation, the maximum permissible lifting load is limited to the nominal load,
according to the marked load bearing capacity. Higher loads are forbidden.

In the European Union, the legislators demand from the operators that instruction manuals shall be
always available and must be communicated to all users. In the Federal Republic of Germany it is
necessary to attach additionally a summary of the Accidents Prevention Regulations BGV D6 with the
essential security advices in a good visible manner directly on the work station of the crane operator.

Operators of crane units as well as the maintenance personnel must have knowledge of the
regulations and rules applying for this. Those are in the Federal Republic of Germany in particular:

        -   Accidents Prevention Regulations Cranes BGV D6
        -   Accidents Prevention Regulations Winches, Hoist and Traction Machines BGV D8
        -   BGR      500     –    Load     suspension      device     at    hoisting    gear     operation

Part A – Operating instructions

   1. Information on intended use
          -    The operator shall catch up on the intended use of the crane before start up. Improper
               use is forbidden.
          -    The crane may be only started up, when the assembly and the equipments comply
               with the valid regulations. (Declaration of Conformity is available, CE- mark is
               attached, acceptance inspection or regular inspection is visible on the test seal and
               still valid)
          -    The crane must be only assembled in an appropriate working environment. An
               accident-proof operation must be ensured.
          -    The assembly must be executed perpendiculary on a floor which is permanently
               capable of bearing, plane, vibration- and oscilliation-free.
          -    In the Federal Republic of Germany, only persons who meet the requirements
               according to UVV (accident prevention regulations) BGV D6 §29 can be appointed as
               crane operators.
          -    The application and the use of the crane are permitted according to classification in
               hoisting class and loading group according DIN 15018 (see information in test book).
          -    The slewing jib crane is intended to lift and drive (in each case power-operated or
               manually) loads on the boom using a hoisting gear. The slewing of the boom may be
               only executed manually, whereby the load must be guided by another person.
          -    Only hoisting gears which have a dead weight that does not exceed the limiting value,
               according to dimensions table [Annex A], may be used on the lifting arm to lift and
               drive loads.*
          -    The maximum permissible lifting speed of hoisting gears on the crane is 8.0 m/min. *
          -    The maximum permissible driving speed of power-operated trolley gears is
               20.0 m/min*
          -    Only hoisting gears with an effective rated capacity limiter (e.g. safety clutch) may be
               used.
          -    The slewing jib crane is designed for a temperature range between –10°C and +40°C.
          -    Only slewing jib cranes with additional mark “F” in their type designation are designed
               for an outside operation and can be operated till wind force 4, provided that the
               operating instructions are observed.
          -    Only slewing jib cranes with the additional mark “ex” in their type designation are
               designed for the operation in potentially explosive areas and can be used in the
               respective area according to their marking on the device and in the test book.
          -    Under operating conditions above the corrosion-protection class C2 or in the
               environment of aggressive mediums, special models are required.
          *) If higher values are permitted, thanks to special designs, they are recorded by the manufacturer in the
          additional data sheet. The additional data sheet is a component of the test book.

2. Usage limits

The use of slewing cranes is limited by the number of load alternations (frequency), the load spectrum
(load distribution) as well as by the design (execution) of the crane. The use of the crane outside of
the intended range can result in dangers to and damages on the crane.

Characteristic usage limits are:
       -    Higher dynamic load:
            Use of hoisting gears and load suspension devices, which require a higher classification
            into loading group and hoisting class, according to DIN 15018, as designated in the test
            book of the crane, e.g. during grab or magnet operation.
       -    Tendency to fractures of brittle materials, e.g. glass panels
            The boom bounces because of the elastic deflection. A gentle set-down is, according to
            the self-supporting length (column + boom), only possible to a limited extend.
       -    Operation at temperatures under -10°C and over +40°C
       -    Use under extreme ambience conditions, e.g. smelting furnances, acid baths and areas
            with strong vibrations.
       -    Actions which influence the static of the crane and its stability, e.g. extensions or
            shortenings of the boom or the column, modifications of attachments, modification of the
            load bearing capacity, subsequent installation of a hoisting gear, bigger or heavyer as
            intended or unapproved welding works.

    3. Warning of improper use

                  The following use of the crane is forbidden. A nonobservance can
                  result in risks for the operator and its environment as well as
                  damages on the crane structure.

            a. The use of a crane which is assembled improperly or an equipped crane without
                  manufacturer’s certifications (Declaration of Conformity, CE mark) or test badge.
            b. The use of a crane which is clearly damaged or defective, maybe also ignoring the
                  blocking and prohibition signs.
            c. Transport of unpermitted loads, such as passenger transportation, transport of fused
                  materials, transport of loads which are heavyer than the permitted load bearing
                  capacity of the crane
            d. Stay under suspended loads
            e. Diagonal pulling, trailing or sliding of loads
            f.    If not perpendicular under the hook or if hoisting gear “Open” – inching operation of
                  the hoisting gear – then release of uncontrolled movements of the boom or the
                  hoisting gear by fixing the load, swing up of the boom by operation of the hoisting gear
                  or interventions on the suspended load

            g. Loose of stucked loads, removal -ofA2

Slewing Jib Crane SSK GSX Slewing range 180 up to 270
h. Slewing of the boom by pulling the control switch
i.   Welding works on suspended loads
j.   Lifted loads – must not be exceeded by additional load, must be set-down during a
     stoppage of the transport process, must not rest in the suspended position if they are
     unattended, must not tilt or knock over into the load cable because of a movement of
     the center of gravity.
k. During a use on the open air ground only such loads (dead weight, geometry, surface)
     may be used, which may be reasonably controlled by the user with the available
     means under the respective wind forces.
l.   Hooking of the crane hook in loads of fixed points and “tightening” of the load-carrier
     for the protection against unintentional movements.
m. Unpermissible high operating heights or operating distances – the crane operator
     must be able to operate the manual operated crane in every position in a save
     manner and to slow the load down.
n. Uncontrolled drive to final positions with a high manual speed
o. Improper anchoring or fastening of the crane, in particular with anchor bolts in the
     bottom flange holes on the column tube
p. Additions not intended or authorised by the manufacturer or design modifications on
     the crane
q. Fitting or mounting to air, water or landcrafts or other moveable machines not intended
     or authorised by the manufacturer. (also cranes)

     The slewing jib crane is not designed for continuous operation (continuous
     load changes in automatic processes).

        Basis for the operation of the crane are the operating manuals for crane and hoisting gear as well as the
        UVV cranes (BGV D6). These documents shall be displayed on place by the operating company of the
        machine. These instructions, advices and directives shall be observed.

        5.1 Control elements

        5.1.1 Power supply switch

                                                           The power supply switch (drawing 3) is located on the
                                                           crane column. Normally, it is attached into the column
                                                           tube, so that only the lockable operation device is
                                                           accessable for the operator. It has 2 settings:
                                                               -      “0“ the contacts are opened, the crane is
                                                                      currentless
                                                               -      “1“ power supply on crane available
                                                           The power supply switch cuts the crane from the power
                                                           supply (all phases). In “0“ position it is possible to secure
                                                           the turn knob by hinging a padlock.

                                                           5.1.4      Control switch
       Drawing 3
                                      The hoisting gear is operated via the control switch (drawing 4). Normally,
                                      the control switch is located on the hoisting gear and connected with it via
                                      the control line. The control line serves for the signal transmission from the
                                      control switch to the control system of the crane and has a strain relief which
                                      avoids a tearing due to the dead weight. The control switch must NOT be
                                      used to slew the boom.

                                      At the trim line “ideal controlling” the control switch is not attached on the
                                      hoisting gear but is located on a control trailer, which is movable in a
                                      separate sliding rail on the boom, independently of the hoisting gear.

                                      The control switch is equipped with operation elements to control the crane
                                      movements as well as with a crane switch (EMERGENCY Stop).

                                                             - A5 -
Never operate the EMERGENCY Stop together with other operation element –
                     this could result in movements of the crane.

5.1.4 Locking device of the boom
(special equipment, serial at operation in oper-air ground)

The locking device of the boom (drawing 6) serves for the secure fixing of the boom in one or more fixed
positions of the slewing range. At cranes which are designed for the use on open-air ground, the locking
device of the boom serves for the wind bracing on one boom position minimum. The operation (Loosening /
Locking) is allowed till approx. wind force 4. Beyond that, very high operating forces occur and the drifting
boom is potential danger. For this reason, only loose the locking device if there is no danger of drifting
booms due to wind.
                                                              The operation takes place by pulling the
                                                              operating rod (A1) till the return stop (A2)
                                                              below the bearing plate is visible and the
                                                              locking bolt (A3) releases the boom (1). Now
                                                              the run-back of the locking pin (A3) is avoided
                                                              by a 90 degree turning of the operating rod
                                                              (A1). The boom can slew freely. If the boom
                                                              shall be locked, it shall be slewed manually to
                                                              a locking position till the locking bolt (A3) is
                                                              located under a drilling / locking strap (A5).
                                                              The locking of the bolt takes place in reverse
                                                              order.

(see mounting instructions paragraph 15.3). Slewing brakes are intended for cranes in closed halls.

                                                - A7 -
5.2.3 Stops for limitation of slewing

According to installation size, crane equipments and intended use, they are a component of the crane
construction or the special equipment (take information from the order documents or the additional data list
in the test book of the crane).
Stops for limitation of slewing shall be employed to:
    -   avoid a crash of the crane boom or of pieces of the equipment assembled on the boom (hoisting
        gear, power supply etc.) on the interference contours in the environment of the crane (e.g. walls,
        supports, other cranes)
    -   limit the working area or the boom
    -   safe attachment parts against crashes on the crane column

Depending on the function 2 types of stops for limitation of slewing are differentiated:
    a) Stop for limitation of slewing with buffer rod for clamping on the boom (counter stops in the
        environment of the crane)

                                                                                   Drawing 9
    b) Stop for limitation of slewing for assembling on the crane basis (counter stop is the crane itself)

                                                                                           Drawing 10
                     All stops are designed as EMERGENCY end stop and must not be arrived during
                     normal operation. (see also BGV D6 § 30).

                                                  - A8 -
6. Commissioning

    -   the statutory acceptance tests (according to UVV BGV D6 § 25) must have taken place before the
        initial operation
    -   the crane must be evidently in a safe and functional condition
    -   the operator must have read and understood the operating manual

Steps before commissioning
    -   visual inspection that all parts are free of external damages and reliably operating
    -   activate the power supply switch on the crane column
    -   unlock the EMERGENCY Stop button on the control panel
    -   loosen the locking (if existing on the crane)
    -   use boom and hoisting gear

Transport of loads
    -   Select adequate slinging means for the choosen load and the transport.
    -   Hinge the load hook and the boom above the load centre into the load or the slinging mean and
        tighten the load cable carefully.
    -   Always lifting the load from the floor in fine motion. Use a faster lifting speed for the lifting to the
        desired height not before the load is hanging safely.
    -   At manually operated cranes, all moves shall be realised by guiding the load or the load cable. The
        crane operator must drive manually and partially power operated cranes so, that he is able to stop
        the released travels and rotations without any danger.
        EMERGENCY Stops (stops) must not be arrived non-braked.
    -   If a direct guiding of the load is impossible, additional guiding aids (e.g. ropes, chains or guiding
        rods) shall be attached on the load, the load hook or the boom.
    -   Keep the transport process shortly and put the load in a safe position and completely down.
        Hang the load hook out and bring it to a safe stand-by position.

7. Decommissioning

The crane shall be stopped at the end of work or longer stoppages of work as well as in cases of
recognized damages or occuring critical situations.

    -   Hoisting gear in standby position
    -   Push power supply switch to 0 condition

In cases of interruptions, shutdown or wind force >4, the booms of cranes in operation on open air ground
shall be locked by a serial locking in its standby position.

                                                   - A9 -

10. Maintenance

 Maintenance works on the trestle crane serve for the maintenance of the operating reliability and the
 functionality and increase the fatigue life of the machine. The maintenance must be carried out regulary
 and by experienced qualified companies and/or qualified persons according to BGV D8 §23 and BGV D6
 §26.

 10.1 General information
 Even though the crane is extensively maintenance free, the components which are subject to a wear must
 be checked regulary.
 With an intended assembly and use of the crane, the service life of any wear parts amounts normally to 10
 years. In case of a stress above average as a result of external influences the service life can be
 shortened, so that the wear parts must be replaced early.

                       Components which are essential for a sure operation must be checked per working day
                       and before every use.

 Inspection interval:            The inspection intervals are fixed on 12 months for all parts according to the design
                                 of the crane for the entire service life.

 The following components must be checked regulary:

 Daily inspection / before commissioning                     –         X

12.1 Types of anchorage

Additionally, it is possible to anchor the crane with a base plate or a foot flange on an adequate
substructure, for example:
            -    On a floor slab using straight fitting and counter plates
            -    On a steel construction with adequate screw or weld joint
The requirements on this substructure result from the individual technical parameters (loads and moments),
as well as from the general requirements on the anchorage of the crane.
For effective loads on the on site anchorage see the purchase order documents or consult the
manufacturer. Information of general dimension and data sheets only apply to standard designs with foot
flange and till the construction height specified there.

Requirements on the foundation – Check before assembly!
            -    Foundation must be sufficiently hardened (clearance through the supervising company)
            -    Foundation shall be checked on compliance with provided outer dimensions
            -    Position, number and arrangement of the anchor bolts shall be checked according to
                 dimension sheet
            -    Number of the drilled holes in the foot flange must conform to the anchor bolts
            -    Diameter and screw thread of the anchor bolts shall be checked

Requirements on the bolt plate – Check before assembly!
            -    Evenness and straightness of the floor
            -    No grooves in the area of the bolt plate and respect of the edge distances according to the
                 admission requirements for anchor bolts (see assembly instructions “Standard and
                 intermediate base plates for the bolt anchorage“)
            -    According to the processing guidelines of anchors, the temperature of the anchorage
                 basement must be between +5°C and +25°C
            -    The minimum requirement on the concrete quality and the contrete thickness of the
                 anchorage basement shall be checked according to the admission requirements and
                 documented in the assembly record

Requirements on the supporting structure on site:
            -    Must be free of oscillation and vibration
            -    Must be able to take load and stiff
            -    Open profiles (such as I profiles) are flexible in torsion and so they must be sufficiently
                 dimensioned and require, if necessary, a bracing to the box girder
            -    The joint and supporting surfaces must be even and horizontal

With an adequate hoisting gear and slinging mean, lift the crane column carefully in a vertical position.
Now, guide the power supply through the column till the hole for the main switch and draw it through the
hole.

Set the column carefully down and pay attention to an insertion of the anchor bolts as gentle as possible to
avoid damages on the threaded end. Fix the column with hexagonal nut (F6), flat washer (F5) and counter
nut (F7).

Security advice:           Observe tightening torques for hexagonal nut (see table 5)!

                   With a water level, check on several points on the diameter of the swivel axis if it is
                   perpendicular. Check in the area of the lower console if it is horizontal.

The adjustment takes place by loosing and tightening (F4) and (F6) carefully.
The fine adjustment of the crane must take place after assembly of the boom and the hoisting gear as well
as with completely assembled equipment and in hardened foundation (see chapter 16.6)

        positions (120) to (122).
    8. Slew the boom to all possible final positions, according to the local conditions, and check if the
        boom stops in all positions. Should this not be the case, observe the possibilities of adjustment
        (see chapter 17)

15. Assembly equipment

The supplementary equipment offered by us is the permitted equipment for the crane. We, as crane
manufacturer, adjust our equipment to the crane and certify the belonging in the inspection records on the
additional master data list. In addition, the crane is intended for the use with hoisting gears and load
handling devices which meet the national accident prevention regulations as well as the current EC
Machinery Directive. During the choice of the hoisting gears, the limitations according to chapter 1
(intended use) and the data sheets shall be observed.

15.1 Assembly hoisting gear

Review and decide in advance, if you pre-assemble the cross travel winch and the hoisting gear on outside
and hang it then into the boom of if the assembly of the hoisting gear should take place directly on the
boom. Assemble the hoisting gear and the travelling winch according to the individual instructions of the
respective manufacturer of hoisting gear. Ensure the correct adjustment of the bottom flange carriage to
the width of the mounting flange of the boom. Consider the clearance on the crab gauge provided by the
manufacturer of the hoisting gear.

15.2 Assembly cross travel stops

The inner cross travel stops are tightly connected ex works with the boom. The cross travel stop on the
head of the boom is removable. They are suitable as final position limitation for numerous cross travel
winches.

                 ADVICE: If the function of the cross travel stops of carriages delivered to you is not
                 ensured, universal cross travel stops in clamping design are available as special
                 equipment.

The following parts are loosely enclosed for the assembly of the cross travel stops:

           1x    Stop angle                     (23)
           2x    Rubber buffer                  (110)

                                      Drawing 20

Please review before assembly:
            -   Do you meet the requirements of welding on cranes?
            -   Allow the environmental conditions on assembly site a welding?
            -   Are all equipments, hoisting gears etc., relevant to define the slewing range, assembled on
                the crane?
            -   Which interference contours in the environment of the crane shall be protected against
                impact of the boom and how must the boom protected against impact?
            -   Decide on which point (Crane column or lower bearing plate) and in which position
                (standing of lying) the universal stop must be welded to fulfil its function.
            -   In this connection, please take account to a maximum long weld seam (GSX design size 1-
                3 minimum 75 mm, design size 4+5 minimum 120 mm).
Assembly:
            1. In the area of the projected welded seam, remove locally the existing anti-corrosion
                coating.
            2. Attach the buffer and check the intended function – if necessary, adjust the position of the
                buffer.
            3. Completely weld the buffer on (hollow weld a=3mm (size 1 to 3) and/or a=4mm (size 4 and
                5).
            4. Check the function of the stops with and without load on the respective final positions of
                cross travel.
            5. Using the included correction colour, renew the anti-corrosion coating in the area of the
                welded seam.

15.5 Assembly locking of boom

The locking of the boom is intended for the fixation of the boom in one or more positions within the
swivelling range of the crane. At cranes for outdoor operation the locking is standard equipment and serves
for wind bracing (see also chapter 5.1.4)

The locking of the boom is pre-assembled ex works on the crane column.

                                                            During the installation of the crane and
                                                            assembly of the boom the locking of the boom
                                                            shall be adjusted in position “loosen” (control
                                                            rod A1 pulled and locked) to ensure a smooth
                                                            hanging in of the boom.

                                                            Check the locking for function after assembly
                                                            of   the   boom   (see    chapter   14) and,   if
                                                            necessary, readjust the slewing bracket.

Drawing 21

During maintenance and repair works, it could be necessary to disassemble the locking to replace for
example the spiral spring. In this case the bolt (pos. A2 and A6 – called return stop) must be replaced and
the control rod can be pulled downwards out of the guide plates. Remove spring and flat washer carefully.
Caution – the return spring is under pre-tension.

The assembly proceeds in reverse order. Position the new spring (A4) and the new flat washer (A7)
between the plates and the control rod into the drilling holes of the guide plates. Lock it with bolt (A2 and
A6) and, after assembly, check locking for function.
