Torque test bench

Torque wrenches, nutrunners, battery tools, and impulse tools can be tested "under real shop-floor conditions without the need to run tests on the production line which could slow productivity", says Crane's Berthold Attelmann. In operation, the joint behaviour of a particular tool is recorded in the assembly area using a rotary transducer and read-out unit from the JRS Opta. Then, the recorded information is downloaded into the Opta memory which can replicate the behaviour of the joint. The test bench's hydraulic brakes can simulate a range of joint conditions from the very 'soft' (20º) to the very 'hard' (720º). "The tool test cycle can be carried out very quickly and once the tool has finished the brake is released automatically for the next test cycle", says Berthold Attelmann. "This speeds up the tool test procedure as there are no fixings to undo or joint kits to reconfigure."
