(a)

 Maximum rated energy at full stroke.

(b)

Hammer operating speed is a function of many variables, including penetration resistance, cushion material, pressure, stroke, etc. Observed blow-count will vary depending on driving conditions. Energy is not a function of speed.

(c)

Without helmet or leads.

(d)

Male jaws except where marked (f) for female jaws. Other jaws available on special orders.

(e)

Steam consumption is based on feedwater and steam temperature of 212 degrees F.

(f)

Compressor output must exceed air required at hammer due to line and efficiency losses. It is advisable that the adiabatic consumption figure be increased by approximately 30%in the determination of required compressor size.
