This expanded line of hydraulic breakers is designed and tested for compatibility with PC78 up to the PC490 excavators.
- Accumulator eliminates hydraulic pump cavitation to prevent flow surges back to the carrier hydraulic tank
- Blank firing protection standard
- JTHB-G line utilizes a hybrid design of hydraulic flow and pressure plus a nitrogen-filled chamber to provide striking energy and features only two moving parts, a patented tie-rod design, hydraulic cushion at the base of the cylinder and key slot dampers (larger models)
- JMHB-H line of accumulator-type models don't require a nitrogen recharge, have a single powercell that eliminates heavy tie-rods and include sound-dampening housings, a pressure regulator valve, vibration dampening system and automatic lubrication
