It is an indispensable logistics and transportation equipment to improve material handling conditions and increase labor productivity in the process of modern economic construction and social production activities. It has been widely used in various fields of economic construction. Today we will talk about the maintenance and repair of specific parts of the crane. 1. Maintenance and repair of the transmission mechanism Check whether the fixing device of the wire rope meets the requirements, and check whether it has corrosion, broken wires, loose strands, broken strands, bending, kinking, abrasion, flattening, etc., if it exceeds the relevant regulations, it must be Replace it immediately; check whether the hook has defects such as section wear, peeling, cracks, torsional deformation, increased opening degree, and whether the relevant pin shaft and sleeve are severely worn; check whether the pulley is equipped with an anti-drop rope groove device, and the pulley rotates Whether it is flexible, whether the pulley rope groove and wheel flange have broken edges, wear, cracks and other conditions. 2. Maintenance and repair of the brake device Check whether the mechanism is running noise and whether the heat dissipation is good; check and adjust the gap between the brake shoe and the brake wheel; check the brake spring and pull rod for fatigue deformation, cracks and other defects; Check the lubrication of the gearbox, reduction box, external meshing gear and other parts and whether the hydraulic oil leaks; often check whether the oil filter is blocked, and whether the adjustment value of the safety valve changes after use; the friction surface of the brake of each mechanism, There should be no dirt. If there is dirt, it must be washed off with gasoline or thinner; check whether the wheel treads and axles have fatigue cracks, whether the wheel treads and axles are worn out, and whether there is track gnawing during operation. 3. During the maintenance and repair of metal structures, it is necessary to regularly check whether the main stressed components have overall or partial fatigue deformation, looseness, instability, severe corrosion, cracks, damage, etc., and try to prevent component deformation and damage during transportation. Collision damage; check the connecting bolts or riveting, especially the vibration parts for looseness, defects and other defects; check the structural connections and welds for obvious deformation and cracking. 4. Maintenance and repair of the electrical system. Clean the dust and dirt on the electrical equipment in time to ensure the cleanliness of the distribution boxes, control boxes, brushes and contact surfaces of each part; always check all cables and wires for damage, If the damaged part is found, it should be bandaged or replaced in time; ensure that the contacts of the travel switch of each safety device are reliably opened and closed, and the contact crater should be polished in time; check whether the crane power supply and each mechanism are equipped with short circuit protection, loss of voltage protection, and zero protection , Overcurrent protection and overspeed and loss of magnetism protection for special cranes. 5. Maintenance and repair of safety protection devices Check whether the installation of overload protection devices, buffers, torque limiters, limit position limiters, anti-backover devices, wind protection devices, and protection devices of the crane meets the design requirements, and the operation of these devices Whether it is sensitive and reliable, whether it can send an alarm signal in time if it exceeds the specification, and whether it can automatically cut off the power source running in a dangerous direction. The above is an introduction to the maintenance and repair of specific parts of the crane. If necessary, please contact Hoisting Machinery Equipment Co., Ltd.!
