A mechanical part of the maintenance: the agencies are required to brake, the functioning of the agencies, the various components of the fastening bolts, the various parts of the wire rope inspection, failure should be immediately removed, check the connecting bolts agencies , welds, and member of the work, time and paint on fastening.
2 hydraulic system maintenance: time to add or replace the hydraulic oil, and check the tubing and fittings, valves, hydraulic pumps and hydraulic cylinders, etc., identify problems promptly.
3 Electrical System Maintenance: wires, cables should be no damage, limit switch safety device shall be reliable, ground protection resistors to meet the requirements.
4 lubrication: tower
steel crane should always check the lubrication of all parts, good lubrication cycle, time to add or replace the lubricant.
5 To ensure the tower crane work, to ensure the safety of man, must be prepared to check, adjust, clean, tight, lubrication and replenishment six content-centric routine maintenance work.
Five, hanging crane maintenance
1 Check the fastening shaft seat, gearbox, coupling and shaft chain.
(2) Check and adjust the brake and brake wheel gap, especially carts synchronous actuator with brake wheel and a uniform gap Emotion and requires sensitive and reliable.
3 Check and adjust the wire rope,overhead bridge crane winches, hooks, pulleys without broken wires, cracks and wear.
4 Check and adjust the brake is sensitive and reliable.
5 Check the gearbox oil level, oil quality, in accordance with regulations to add new oil, while bearing, brake frame, couplings inject the right amount of grease.
6 Check the limit switch is sensitive and reliable, pantographs are safe and reliable, electrical boxes to clear singeing part exchange contacts, guards are complete and valid.
7 See lights, telex is valid and reliable.
8 Wipe the crane appearance,bridge gantry crane do not accumulate fat, grease, rust, complementary ministries fasteners, keeping equipment clean intact.
