due to the inertia of the system could not produce coasting fall

Do not pay attention to maintenance from the weight of limiter does not regulate the limiter from the weight on the use of, electromagnetic overhead crane or even deliberately do not, or increase the limit value, so that from the weight of limiter should not restrict the protective effect.The lifting mechanism brake not adjusted too loose. When overweight high speed decentralization, over head cranes due to the inertia of the system could not produce coasting fall.
