Installations Specifications
Gas Charging Pressure
- Back-head (Piston accumulator) 2): 9 ~ 10 (130 ~ 145) bar(psi)
- High pressure accumulator: 60 (870) bar(psi)
Hydraulic Piping
- Line size (min. internal diameter): 32 mm / 1 1/4 in
- Acceptable back pressure (max.) 3): 10(150) bar(psi)
Hose connections of breaker
Oil supply (IN) & return (OUT): BSP 1 1/4″ O-Ring Boss Female
Pressure Relief (min.): 40 (600) + measured max. operating pressure
Acceptable Hydraulic Oil
- Operating temperature 4): -20 ~ +85 (-4 ~ +185) °C(°F)

Notes
- The prefill nitrogen gas pressure measured statically (breaker not operating) without down load on the tool at the stabilized gas temperature of +20 °C.
- The recommended value at the normal operating condition (supplied oil flow, oil temperature and viscosity, etc.).
- The maximum allowed oil pressure at the breaker’s connection point to the return line (measured statically without the breaker).
- The allowed temperature limits when using the oil of viscosity grade 46.
Available Tools (CHISELS)
Notes
- The diameter of the tool portion outside the breaker body.
- Other special designs are also available on request.
