TORQUE ARMS / TORQUE TUBES & TORQUE MANIPULATORS

Torque Arms / Torque Tubes are devices that support tightening tools such as torque guns, nutrunners and screwdrivers.

Torque Arms provide 2 main benefits:

1) They absorb the torque that is generated during tightening
2) They provide lift for the nutrunner, so that the nutrunner floats at all times on the end of the arm

The ergonomic benefit of torque arms increase as tool weight and torque are increased.

Givens Engineering offers an assortment of torque arms for a wide range of torque applications up to 750 ft*lb (1000 N*m).

STD-TA
(TORQUE ARMS)

The TA2 and TA5 series of torque arms are pneumatically balanced, dual articulating arms.

Our torque arms are sized for medium to high torque applications: 225 N*m [167 ft*lb] (max) for the TA2, 565 N*m [417 ft*lb] (max) for the TA5.

(RIGHT ►) - A TA2 torque arm with Atlas 90° nutrunner rated for 2000 in*lbs (225 N*am) torque. The nutrunner clamp is custom and allows the nutrunner to spin about its axis

Torque arms are typically column mounted but it is possible to mount torque arms on a carriage so that it may be moved along an assembly line.

Our basic torque arms are not supplied with a tool holder due to the multitude of applications. A tool holder may be quoted as an optional extra for any torque tool

STD-TA2 TORQUE ARM Max Torque 2000 in*lbs (225 N*m) Standard Arm Lengths 21.5", 30", 40" Payload 30 lbs Balance Cylinder Size Ø3.25" bore x 4 stroke Standard Post Height 85" Max Operating Pressure 100 psi

STD-TA5 TORQUE ARM Max Torque 5000 in*lbs (225 N*m) Standard Arm Lengths 30", 40", 50" Payload 50 lbs Balance Cylinder Size Ø5.0" bore x 4 stroke Standard Post Height 91" Max Operating Pressure 100 psi

STD-SA70
(SPATIAL ARMS)

(SPATIAL ARM) The SA70 is a modular torque arm for smaller torques, assembled from standard components. The dual articulating arm is mounted on linear bearings rather than parallel linkages. Lift is provided by an air cylinder.

STD-SA70 SPATIAL ARM Max Torque 620 in*lbs (70 N*m) Standard Arm Lengths 15" Arm #1, 15.5" Arm #2 Payload 50 lbs Max Vertical Travel 9" Standard Post Height 91" Max Operating Pressure 100 psi

STD-TT
(TORQUE TUBES)

Torque Tubes are a lower cost alternate to torque arms and the spatial arm. Torque tubes generally hang from crane rails and normally cannot withstand the same torque levels as torque arms. Movement is straight up and down, balanced by a spring balancer or an air cylinder. Torque tubes can be made to fit almost any brand of enclosed rail.

STD-TT2 TORQUE TUBE Max Torque 2000 in*lbs (225 N*m) Payload 50 lbs Max Vertical Travel 23" Crane Rail Compatibility Determined at order. Can be built to suit any brand of enclosed rail.

STD-TT5 TORQUE TUBE Max Torque 5000 in*lbs (562 N*m) Payload 50 lbs Max Vertical Travel 18" Crane Rail Compatibility Determined at order. Can be built to suit any brand of enclosed rail.

STD-TM
(TORQUE MANIPULATORS)

Torque Manipulators are based on our STD-M series of industrial manipulators. With some minor modification, these devices can accommodate heavy tooling and very large torques.

STD-TM15 TORQUE MANIPULATOR Max Torque 4400 in*lbs (5000 N*m) Typical Reach 9' (108") Payload 100 lbs Options *Brakes are optional at all 3 axis *Non-Standard Post Height *Inverted first axis available for overhead mounting

STD-TM25 TORQUE MANIPULATOR Max Torque 8850 in*lbs (1000 N*m) Typical Reach 12' (144") Payload 150 lbs Options *Brakes are optional at all 3 axis *Non-Standard Post Height *Inverted first axis available for overhead mounting

TORQUE MANIPULATOR CUSTOM ACCESSORIES

Givens Engineering can design and build custom accessories for your torque manipulator application.

Notice the shot pin at the right, which locks the nutrunner at different angles.

When a trombone is used, there is always the possibility of "torque lock", which makes it impossible to remove the tool from the tightened fastener. To prevent this, we provide an anti-torque-lock device that allows the nutrunner to move free of the fastener.

OTHER TORQUE TOOLS
