In recent years, the goal of driving the price, cranes and other lifting equipment line trends appear stable growth, with the continued development of China's economy, the goal of driving the recovery, crane market has been rapid growth, according to Chinese mining machine with tons Product Packaging shipments increased, often used for hanging, lifting rope, stopper damaged, resulting in increased and accessories. In order to implement the "safety first, prevention first" safe method; strengthen safety management, the goal of the state road, reducing maintenance company's capital, to eliminate unsafe behavior, preventing 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; good line hanging conservation prolong the useful life line hanging line hanging into care and maintenance of machinery and equipment maintenance and repair, hydraulic climbing system maintenance and repair, care and maintenance of metal structures and electrical systems maintenance and repair. Here should pay attention to all aspects, all aspects should not be overlooked. Maintenance of line hanging to note that the main brake agencies, brake wheel, interior gantry driving, gear box, transmission, and various parts of the rope guard. Hydraulic climbing system needs to be noted that the main fuel and the tank internal pressure regulator, take note of the portion of the joint, oil filter, fuel pumps, fuel tanks and control valves. Maintenance line hanging metal structures main attention during transport to prevent deformation and collision damage components, when used to carry out regular maintenance and care, but also often members are deformed, damaged or loose. Maintenance of the electrical system is mainly to check the circuit in this regard, but also includes brushes, equipment boxes and safety devices in these areas, when the motor is overheating when you want to stop in time, for maintenance. Small gantry driving, generous heavy (online consultation), the goal of the state is provided by Henan generous driving heavy machinery Limited. Heavy Machinery Co., Ltd., Henan Province, generous (www.hnqizhongshebei.com) (www.hnqizhongshebei.com) is Zhengzhou, engineering, construction cranes leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. In heavy generous leadership with the staff warmly welcome all inquiries negotiations to create a better future for heavy generous.
