Hydraulic hammers deliver maximum force

Volvo Construction Equipment

The Volvo HB1400 hydraulic hammer for the EC210CL crawler excavator can break concrete with an impact force of 2,500 pounds per foot. The Volvo HB2400 hydraulic hammer is designed for Volvo EC240CL and larger excavators and can break concrete and bedrock with a maximum impact of 6,000 pounds per foot.
The long, heavy piston matches the diameter and weight of the work tools for maximum transfer of energy from the hammer to the ground material. An integrally top-mounted accumulator guards against pressure peaks and helps the piston keep consistent power. And the pressure-control valve keeps the hammer striking at full force, even if hydraulic pressure from the excavator changes.
