Caterpillar’s B20, B30 and B35 top mount hammers (TM) are now available locally for diverse markets that include municipal, general construction, demolition, quarrying and mining.
These units are designed for fitment across a broad spectrum of Cat carriers: the B20 TM is an ideal match for the Cat 320D2 L; the BM30 TM for Cat 323D2 L and Cat 329D2 L machines; and the B35 TM for Cat 336D2 L and Cat 340D2 L excavators.
“A distinctive feature is their excellent power-to-weight ratio, outstanding impact output, and simplicity,” points out Barloworld Equipment product and application specialist, Craig Christie, adding that the weld-free hydraulic kit mounting supplied is a standard feature. “This high pressure accumulator protects the carrier’s hydraulic circuit by absorbing pulsation spikes created during the firing stroke.”
Caterpillar’s B-Series gas fired hammers are characterised by their top-mount (rectangular) style, which increases impact power by keeping hammer and stick forces in line. The top-mount style also provides a larger work area and sound operator visibility. Additionally, the top-mount bracket configuration transfers far fewer forces and corresponding bending stresses into the end of the stick, lowering the overall impact on machine structures. Hammer speed/frequency can be adjusted easily to suit specific applications.
In terms of maintenance, the full length side plate design provides personnel with much easier access to service points and change-outs. A prime example is the field replaceable lower tool bushing. Tools come in moil, cone, chisel and blunt specifications and all are manufactured using high grade heat-treated steel.
