Cat introduces E-Series breakers
By Lindsay Gale23 February 2015
Cat has introduced four new hydraulic breakers in the E Series to replace their D Series predecessors. The 130 kg (286 lb) H35E, 250 kg (550 lb) H45E, 340 kg (748 lb) H55E and 380 kg (836 lb) H65E are available in two mounting configurations for installation on both Caterpillar and other carrier brands. All four are also available as silenced versions (with the ‘s’ designation following the model number) that use a fully enclosed housing to suppress noise.
These hammers are designed and engineered to match auxiliary flows and pressures of Cat machine. Flat-top models allow versatility for installation on Caterpillar and equipment made by other manufacturers. Pin-on models are available for the H55E and H65E in applications that require a dedicated, hammer-equipped Cat machine.
The suspension system on the silenced models include buffers at the top and bottom to absorb reflective forces and isolate them from the machine and a suspension jack helps to dampen vibration and sound. The result is quiet, reliable operation and reduced operator fatigue. To protect the hammer from internal stress, an automatic shut-off can be activated that instantly stops the piston when the hammer breaks through material, in turn protecting the hammer from blank-firing. With 47% fewer parts than their D Series predecessors, the new hammers can be serviced more quickly and easily said Cat, with a single lubrication point simplifying daily maintenance.
