Hydraulic Hammer

A hydraulic hammer shouldnt be chosen strictly on the basis of the reach, stability, or hydraulic capacity necessary, but also on the vehicle on which the tool will be mounted. Keep in mind that for a given reach, the heavier the hammer, the heavier the carrier vehicle must be. The weight of the carrier vehicle prevents overturning when the hammer is at the boom's maximum reach. Selecting a lightweight carrier decreases the boom's reach and could cause an overturning accident.

Also, remember that while most hydraulic systems run 2000-psi pressure, the flow rate varies. For the light hammers, as little as 5 gallons per minute is required. For the heavy hammers, more than 100 gallons per minute must be supplied. Again, check the hammer and carrier manufacturers' literature to match the hammer to the vehicle. If necessary, add-on hydraulic power units are available to increase the flow rate.
