The Gray Chain 3570 AIR offers the ultimate in simplicity and rugged design.
Designed to be compact and self contained; the GrayChain 3570 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 GrayChain 3570 should be
palletized and covered to be kept dry and free from moisture. The GrayChain 3570 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.
