The Mark 40 offers the ultimate in simplicity and rugged design. Designed to be compact
and self contained; the Mark 40 does not require a stand-alone power pack. All the gripping
pressure and spinning torque are generated at the drill pipe spinner. In standard rig
installations a spring hanger assembly is provided.
Keep in climate controlled environment where possible. The Mark 40 should be palletized
and covered to be kept dry and free from moisture. The Mark 40 should be inspected for
any rust or corrosion especially after storage and before use. All points of any type of rust
or corrosion should be properly maintained or replaced prior to start up. Apply grease to all
lubrication points prior to start up. Any parts showing signs of rust or corrosion should be
thoroughly inspected prior to operation.
