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.
