STAHLWILLE 52110091 - 7791 - Mechanical loaders up to 400 Nm

Mechanical loaders up to 400 N-m.
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. Patents applied for.
