In order to ensure the reliable operation of cranes, gantry crane application enterprises to do a good job in the regular maintenance of cranes, maintenance and repair work, I sorted out a relevant rules and regulations, so that companies refer to the application. The project shall carry out collaborative inspection on the crane subordinated to the project on time every Wednesday. The inspectors are composed of the project supervision, project safety, quality, materials department and electric welders. It is required that the actual operator should carry out the inspection of the crane before and after the shift every day. The actual operation staff should estimate the working condition of the lifting equipment and the condition that the crane can estimate at any time and anywhere. Keep records of testing and maintenance. Find the problem, stop the work, immediately report, until the problem is identified or repair can be used again.
Steel structure engineering: Check the connection, crack, crack, deformation, rupture, corrosion and other abnormal conditions of steel structure engineering. Operation organization of door crane and car: check whether the rubber bearing and shaft, key, coupling device and reducer box of rotating shaft are loose, and tighten them; Check and adjust the brake gap of the brake system, stipulating that the touch is good, smart and reliable; Check the rotation status of the walking wheel. Lifting organization: Check whether the galvanized wire rope is intact or not. If there is broken wire damage, it should be replaced according to the technical standards. Check whether the crane hook, roller crack and relatively serious damage; Check and adjust braking system and positioning equipment, stipulate safety, dexterity and reliability. Lubrication equipment: for all rolling bearings, brake system hinge points, fitness parts in accordance with the lubrication regulations, fill appropriate quality lubrication liquid; Check the oil quantity and oil product of gear reducer, and add or remove grease as needed; Check all smooth points without oil seepage.
Electrical equipment and control equipment: check the control cabinet, replace the circuit breaker; Check, adjust, remove and replace the motor brush; Check whether the conductive slide frame is loose, whether the travel switch is convenient and reliable; Check whether the protection equipment is complete, tight and reliable. Clean, neat: clean the various positions of the door crane, no dust, no oil, no rust; Check and tighten the damaged parts and screws in the repair position regularly and maintain details. Maintenance rules and regulations, maintenance maintenance points on time and regular maintenance: according to the maintenance provisions of the crane to carry out the actual operation staff must strictly carry out the maintenance on time and regular maintenance of the actual operation staff must do a good job of maintenance maintenance records maintenance maintenance category. Steel structure engineering: Check the connection, crack, crack, deformation, rupture, corrosion and other abnormal conditions of steel structure engineering.
