long-life operation, and simplifiedmaintenance. For example, a single grease point provides
hammer paste to tool bushings; and the power chamber and accumulator pressures can
be checked and charged while the hammer is mounted on the machine. The power cell
is designed for efficiency with only two major components, namely the front head and
valve body.
“Caterpillar’s tri-suspension system guides the power cell and reduces noise and
vibration,” explains Barloworld Equipment product specialist, Craig Christie, expanding
on technological features.
“During operation, the automatic shut-off function eliminates blank firing and reduces
internal wear, protecting the hammer from less experienced operators, whilst an integral
accumulator protects the carrier pumps from hydraulic spiking, ensuring consistent
performance,” Christie adds.
