Right Angled Rolling Drives
Right Angled Drive Motor
Pneumatic Right Angled Rolling Drives are the ideal rolling motor for tight spaces. Sometimes in boilers, tubes in tube sheets are not accessible. But you must 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 Pneumatic Right Angled Rolling Drives operate on 90 PSI continuous 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, 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.
CAUTION.
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.

Associated Equipment
Pneumatic Motors - Reliable Air Supply
Diesel Compressors
A diesel compressor is a reliable source of air at a consistent CFM’s. The right angled rolling drives needs around 72 CFM’s and if two rolling drives are being used this must be taken into the requirements needed on-site.
Reaction Arm
The amount of reaction force from these pneumatic rolling motors can take the operator by surprise and a dangerous situation can exist. When working with tube expanders and thick wall tube it is sometimes better to have two operators on each rolling motor. One will operate the drive while the other takes charge of the reaction force on the reaction arm.
CAUTION.
Experience is the key to a safe environment with these rolling motors.
Female/Female Sockets
Looking at boiler tube expanders, the drive is always a male square in either 3/4″ or 1.0″. Therefore, with the drive on the pneumatic rolling motor being male, female to female sockets are required. However, the P72-RT-190 is fitted with a 5/8″ square drive and the P72-RT-90 with a 3/4″ square drive. These sockets and associated equipment is supplied when purchasing the rolling motor.
Quality of Product
We work to high tolerances for all machining of expanders including associated equipment. This allows accurate expansion, achieving perfectly sealed joints in tube sheets and in addition, using the best tools steel and cryogenic processes for hardening and conditioning and giving our tooling the optimum performance in the harshest surroundings. We assemble each expander while checking the quality of the manufacture. Every individual tool is laser-marked with our name, Powermaster Canada. Also, we mark with the tube OD, wall thickness and expansion range. We oil, bag and box expanders for shipping. Therefore, with our quality control and machining excellence, we supply a tool that stands the test of endurance and reliability.
