Chain hoists and other lifting equipment, while prohibiting overloading used, but overloading phenomenon still exists, due to overloading caused by the use of lifting incidents have also occurred, in order to avoid overloading chain block , so to limit the development of the debugger, but the debugger , some matters should pay special attention.
(1) To simplify the debugging process to improve numerical accuracy, debugging using electronic crane, chain hoist in the specification more weights can simplify the configuration;
(2) run-in phase should focus on before the whole assembly, if the conditions can be configured ergometer, positioning device, control system established to reduce the work running test bench strength improve work efficiency;
(3) hoists the load limit load debugging adopted, try to set a different interval, the same specifications used when debugging the load slightly larger slip values;
(4) load limit not a substitute for
manual hoist factory debugging dynamic load test, because two persons emphases and different ways, and load requirements are not the same.
Based on the above considerations debugging load limit chain hoists, hoist load limit can greatly improve the accuracy and stability.
Rust-proof chain hoists work is essential, not only affects the overall appearance of the gourd with a great influence on the future use, chain hoists antirust measures described below:
(1) chain hoist hook bearing, to inject calcium-based anti-rust grease to rust.
(2) the various parts of the body
lever hoist the machined surface of an exposed table exposed threaded surface, painted barracks or other calcium-based grease rust rust grease.
(3) chain hoists body gear box, gear should be coated with anti-rust grease oil barium sulfate, and shall be regularly inspected corroded and protection. Such as rust, chip or bamboo hardwood hang required to re-rust oil coating.
