THE Bartrum Group, the Diss, Norfolk, haulage company, is now operating 12 trailers fitted with new axles specially designed by Rubery Owen-Rockwell to take lightweight Aloca alloy wheels.
The principal benefit is that on each tractive unit/trailer cornbination using alloy wheels, Bartrum is able to achieve a weight saving of 0.25 ton. Thus the trailers are able to carry a heavier payload.
In addition, the wheels are machine finished on all surfaces and the consequential true running can have the effect of increasing tyre life.
The TM/T22510/ZMX(A) axle incorporates longer wheel bolts and deeper hub spigots to accommodate the alloy wheel's thicker naves.
Bartrum has also fitted 70 of its trailer fleet with RO-R's Anchorlok ES trailer spring brake system, primarily for safety reasons, although speed and convenience when parking were also important considerations.
