- Measurement without shifting the point of application of force.
- MANUTORK® 7791 significantly reduces the force and time required for calibrations and adjustments of torque wrenches.
- A special force transmission system prevents shifting of the force application point during the calibration process.
- A handwheel drives a lever which is moved linearly by a spindle and thus transmits a rotary movement to the transducer.
- Due to reduced transverse forces on the transducer and a frictionless torque wrench support, measurement errors are largely avoided.

Eigenschaften
- measurement possible without moving the point of application of force
- thanks to a specially designed force transmission system, mechanical loader No 7791 avoids the risk of the point of force application shifting during the calibration process
- the lever below the test rail is actuated in a linear direction by the handwheel acting on a spindle
- the linear motion is translated into a rotary movement which acts on the transducer
- the torque wrench to be calibrated remains in the same position throughout the calibration process
- this prevents measuring errors caused by the point of force application being moved
- thanks to a low-friction linear ball bearing, the torque wrench is automatically levelled as it is placed in the unit
- a further linear ball bearing ensures the contact with the torque wrench is friction-free
- the reduction in lateral forces acting on the transducer and in the friction on the point of contact with the torque wrench results in a corresponding reduction in mismeasurement
- protected by national and international patents
