Line hanging to run the preparatory work row for the heavy lifting as a straight up and down the road lifting equipment, there are two drive: drive and are driven focus. Preparations before running line hanging, we need to run the line before hanging ready to make the line hanging to run properly. 1, test: Under no-load conditions, the power, start and check the moving parts. The operation of control systems and safety devices should be sensitive, safe and reliable, can be used. 2, shall not exceed the prescribed crane lifting weight using do along the beam direction oblique hanging, cable-stayed. 3, check and discover whether all parts of the crane after abnormal phenomenon, if not, before the start line hanging. 4, lifting the front line running to do the wheel bearing lubrication. In recent years, the boom appears lane, line hoists and other lifting equipment development trend of steady growth, with the continued development of China's economy, the crane market has also been rapid growth, according to Chinese mining machine with tons of packaging Product shipments increased, often used for hanging door driving, lifting rope, stopper damaged, resulting in increased and accessories. In order to implement the "safety first, prevention first" safe method; strengthen safety management, reduce maintenance company's capital, to eliminate unsafe behavior of electric driving, prevent unsafe condition. Make safe production rule-based, evidence-based, to ensure safe production, induction examination 1. Do not overload the lifting operations; 2 non-load operation of the suspension of the head by other operators; weight lifting is prohibited under 3 ambiguous situation hanging rivet body skewed hanging prohibited; 4 non-lifting limit device opens parking machines used; cantilever driving, generous heavy (certified), Yangbi county road by heavy machinery Co., Ltd., Henan Province, generous.
