GBCRANES' GWH series hook block is compatible with 1-20 ton steel wire rope hoists. It is much easier for customers to display the load by replacing the hook blocks directly rather than modifying the circuit for installing the load display screen. The weighing accuracy is within ± 2%, and the model is GWH-5/GWH-6.3/GWH-8/GWH-10/GWH-12.5/GWH16/GWH-20.
