Test bench for wrenches
November 1st 2006 Subject to frequent testing, mechanical torque wrenches can represent a cost efficient solution for certain production areas. Crane Electronics has devised a Torque Test Bench which enables manufacturers to test their mechanical wrenches and automatically document the results of these tests. Removing the need to record the readings and calibrations on paper which can lead to labour savings. Easy to use, the test bench permits up to six stationary transducers to be mounted on it. To test a wrench, the adjustable wheel housing is moved along the bed of the test bench until the wrench handle sits on the cradle. Torque is then applied manually via a gear box with the transducer being connected to a TorqueStar Opta. This torque readout device indicates the results of the tests numerically on a display and as well as HI/OK/LO via LEDs. The gearbox allows high torques to be applied but ensures that the operator does not exceed the rate of increase for the torque specified. The design of the test bench also allows easy interchange between transducers. More articles from Crane Electronics Ltd: |
