These loaders allow torque wrenches to be calibrated or tested in accordance with ISO 6789, BS EN 26789 and American military standard GGG-W-686. Their function is to take full advantage of the accuracy of the TTT torque measuring system by reducing operator induced variations in the calibration process.

• The design allows for easy interchange of transducers using the Norbar TTT and Static Transducer system.
   

• Floating reaction point minimises side loads on wrench.
   

• Optional Small Reaction Plate (Part Code 20588) allows torque wrenches down to 125mm in length to be tested.
   

• The high ratio, 1250:1 gearbox allows high torques to be applied, whilst ensuring that the operator does not exceed the rate of increase of torque specified in the standards.

• Reaction extension bar allows wrenches up to 2200 mm to be tested. This can be removed to save space.

Note: Min and Max torque wrench lengths are from the centre of the square drive to the centre of the handle.
