BCA offers factory certified head maintenance program
Every company that owns tire shredders knows the difficulty maintaining equipment and finding skilled millwrights and technicians.
BCA offers it’s customers an alternative to these problems allowing a whole 1000 series head to be shipped LTL back to the factory
for structure priced knife sharpening and head service. BCA sends at no charge a custom steel pallet for head shipping. The unique
design and weight of the 1000 series has made “true portable” high torque shredders possible and also allows inexpensive head
shipping for factory certified knife and head rebuilds. With the modular design an owner can simply rotate the heads use in 1 hour and
suffer no downtime from profitability while saving the cost of highly skilled employees needed to do this work on any other brand of
shredder. Complete head rebuild and knife rebuild starts at just $5,000 including factory certified warranty for the work so you know
it is to original specifications. According to Doug Bartelt President of BCA “we have also added the optional 140HP John Deere
Turbo Diesel to our portables for a very low negotiated price increasing throughput on the hydraulic shredders and engine durability.”

Harry Pearl, chief executive officer of Roadmender Asphalt,
explained: "Having been through 10 years of austerity, coun-
cils have naturally gravitated towards innovation as the only
viable way to safeguard their road assets."
As part of this, councils have set up knowledge-sharing hubs
and innovation-funding initiatives that encourage the devel-
opment of new materials and working methods aimed at driv-
ing down costs and improving efficiency.
Roadmender Elastomac is a by-product of this drive for inno-
vation that has ultimately led to the creation of a new road
repair system that is faster, less expensive, uses 90 percent less
virgin material than traditional repairs and has the ability to
recycle hundreds of thousands of tires a year in the process.
The use of these new flowable materials also eliminates any
hand-arm vibration and airborne dust issues traditionally
caused by saw cutting and jackhammering out potholes, the
company said.
The news comes as Roadmender has been helping authorities

such as pothole filling.
