Right Angled Rolling Drives

Pneumatic Right Angled Drives

Right-angled rolling drives are the ideal rolling motor for tight spaces. Sometimes in boilers, tubes in tube sheets are not accessible. But you have to roll in places where conventional electric drives will not work. Right-angled rolling drives are available in two sizes. They cover tubes up to 4.0″ OD.

The Rolling Motors operates on 90 PSI air pressure. Yet, does not depend on controlled air pressure to maintain accurate torque. Achieving accurate torque is by setting the clutch to the desired torque. The tool will shut off automatically at the torque. Releasing the throttle will allow the tool to reset for the next cycle.

There are two models available, a roll throttle style and a lever throttle style. The lever style becomes activated by simply pressing down the lever. For the roll throttle style, simply rotate the handle in either direction. This will automatically engage a direction of rotation while simultaneously activating the motor. To shut off the motor, simply release the handle and it will return to its center-off position.

Torque Control

With the angle head end facing away. Rotate the handle in a clockwise direction to drive the motor in a forward direction. Rotating the handle in a counter-clockwise, drives the motor in the reverse direction. 


If the clutch, When adjusted over the maximum power output of the tool. The clutch will not function and the tool will operate like a stall-type tool. Also, if the tool is being operated at its upper torque limits. A drop in air pressure could cause the clutch not to function. Whereas a loss of motor power and the tool will function like a stall-type tool.

When the motor is not running, Uncover the rotate the adjustment cover. With the angle head end to the tool facing away, use a 5/32” diameter pin to rotate the adjusting nut. Clockwise to increase the torque setting and counterclockwise to decrease the setting. After adjustment, rotate the cover over the slot to lock the nut in place. When storing this motor, set the torque back down to A1. This will take a majority of the tension off the clutch before storage.
