What is the content of the crane regular inspection?
(1) Weekly inspection A regular inspection shall be carried out every week. The problems found in the inspection shall be handled mainly by the driver, and those that the driver cannot handle shall be handed over to the maintenance team for handling. B weekly inspection content; A according to the contents of the daily inspection system to check, clean. B check the contact of contactor and controller and the corrosion of contact surface. C Check the operation of the drive mechanism of the controller. d Check the coupling of the coupling and the tightening of the screws. e Check the wear of the brake shoe. f Check the wear of the wire rope. g Double brake lifting mechanism, the size of the braking torque, should be checked. h Check the buffer, limit gear iron and rail terminal gear iron.

Common Faults and Troubleshooting Methods of Bridge Crane
1. The brake fails (the brake torque is small, and the lifting mechanism slips the hook). Slipping occurs in the operating mechanism. The reason analysis and its solution are described as follows. 1) There is oil on the surface of the brake wheel, and the friction coefficient decreases, resulting in a decrease in the braking torque, so the car cannot be braked. Kerosene or gasoline can be used to clean the surface oil can be solved.

What is the scrap standard of crane wire rope?
(1) According to the GB6067-85 standard, when the safety factor is less than 6, the number of scrapped broken wires of the alternating twisted steel wire rope is about 10% of the total number of steel wires of the steel wire rope. When the safety factor is 6~7, the number of scrapped broken wires is about 12% of the total number of steel wires of the steel wire rope. When the safety factor is greater than 7, the number of scrapped broken wires is about 14% of the total number of steel wires of steel wires, the number of scrapped broken wires of the same-direction twisted wire rope is half of the number of scrapped broken wires of the alternating twisted wire rope.

What are the safety requirements in crane operation?
(1) The driver should concentrate on the operation, pay close attention to the surrounding situation, and shall not do anything unrelated to the work. (2) The driver shall not operate under any of the following circumstances: A Overload or object weight is not clear. Such as lifting embedded objects with unclear weight or pulling force, and oblique pull slanting, etc; B structure or parts have defects or damage that affect safe work, such as brake, safety device failure, hook nut anti-loosening device damage, wire rope damage to scrap standards.

Problems worthy of attention in load test of hoisting machinery
Load test is an important indicator to test the quality and safety performance of lifting machinery products. The load test can not only detect the deformation of the metal structure of the crane, such as the deflection value of the bridge crane, but also detect the effective situation of the crane safety device, such as the overload limiter, the movement protection of the moment limiter of the tower crane under the rated load state, etc.
