Torque Arms

Torque Arms

For custom-made and highly engineered torque arms and tool holders, trust Givens Lifting Systems to design and manufacture the torque handling solution to suit your unique needs. Whatever the height, weight or torque required, there are virtually no limitations in terms of the customization we can incorporate into our specially designed torque arms.

Torque Arms For Any Application


Torque Arms have 2 roles: 

  1. When tightened, they absorb torque generated by the process. 
  2. Torque arms provide the necessary lift so that the nutrunner floats at all times on the end of the torque arm, following naturally horizontally and vertically.

Designed specifically to float on air, our torque arms are extremely easy to maneuver. In general, the arm itself is mass-produced and stocked. The toolholder however, is custom-made for the specific application at hand. The toolholder can be very simple or can be more complex and include brakes or other unique functionalities.

Torque Arms with Muscle!


A nutrunner consists of a servomotor and a gear reducer controlled by PLC and monitored through an HMI. Refer to images right and below. The torque arm rises to a height of 4m on a pneumatic slide and applies a torque of 160Nm (120 ft-lb). The number of rotations and the torque are continuously monitored and logged.

1000Nm (750 ft-lb) of torque! Applied to large fasteners in a military vehicle. When you need really serious torque, we can provide a serious arm.

Torque Arms Features


  • Torque arms are made to assist the operator in supporting the weight of the end effector/tooling
  • The use of torque arms allows a workload to ‘float’, therefore there are no up/down push buttons required
  • Torque arms are lightweight and agile. The axis assemblies are made of anodized aluminum
  • Soft-stops at the first and second axis are adjustable
  • Torque arms are clamped to the post, the height can be adjusted

Optional Torque Arm Accessories


  • Torque Brakes are available for the first and second axis, to eliminate drift
  • Bearing block assemblies are available at the end of the second arm allowing the end effector to rotate 
  • The parallel arms can be fitted with vertical travel stops 
  • The STD-TA series can be fitted with encoders to track the position of the tool so that individual torque values can be programmed for every fastener
  • Torque Tubes can be used instead of torque arms – when it is necessary to hang a nutrunner from a crane  

There are many torque arm models to choose from based on required torque, arm size, payload and typical reach. The chart below demonstrates the differences between the main torque arm models and their unique capacities.

Total capacity is always a combination of torque and payload; always consult a Professional Engineer before designing a torque arm.
