SSW40 PNEUMATIC SPINNING WRENCH
An easy adjustment screw eliminates the need to change rollers and can accommodate drill pipe and
drill collars from 3.1 /2" to 9.1 /2" OD.
The speed of the SSW40’s four drive rollers, powered by two motors, is precisely controlled by the
operator to permit the slow walking in of drill collars or fast spinning in or out when tripping pipe. In
a typical spinning operation the rig hand swings the SSW40 onto the pipe just above the joint upset.
The clamp control is pulled and the throttle handle actuated to spin in or out with absolute precision.
For added safety a spin direction lockout feature is included to prevent spinning pipe in wrong
direction and comes with added safety valve, which prevents the tool from being closed without pipe
in tool.
