Abstract
A device, system, and method for testing and measuring the grip strength of tongs for a crane system is provided. The device may include a frame body carrying a testing assembly configured to measure the tong grip strength. The system may include the grip strength tester used in conjunction with a crane including an operator tower and a pulley assembly operatively connected to the tongs. The method of use associated with the tong grip strength tester may include the steps of expanding a distance between teeth on the tongs and positioning the teeth adjacent sides of the testing assembly, then closing the tongs thereby clamping teeth to the sides of the testing assembly. Then, the testing assembly measures the compressive force associated with the tongs and registers the compressive force in a computer system to determine whether the grip strength is sufficient to lift a weighted slab of material.
