Reconstruction of the whole machine: (1) The electric gourd can be removed for the phenomenon of the top, repaired it, and the damaged parts can be replaced. (2) For shaking, it is necessary to reinstall and adjust the small workshop space of 4 ~ 5mm, and repair the type beam (adjustment and repair of the installation unit). (3) For rail display, it is necessary to reinstall and adjust (adjustment unit adjustment) to repair the beam (restoration of the crane manufacturing unit). (4) Three feet of gourd running small cars need to be repaired, fixing the word beams, and replacing the small wheels (the crane manufacturing unit repair).

Specifier reconstruction: (1) Add lubricating oil to the noise exceeding the allowable value. After checking, repair the place where the gear bumps and the hair will be changed or the gear and tooth shaft will be replaced. (2) Oil from the hollow axis and penetrate into the rolled tube shell. To let the excess oil volume, or replace the oil seal in the hollow shaft. Replace it with the label oil indicated by the manual. (3) Oil leak oil at the seam of the box cover, replace the oil seal, and fix the box cover to connect the bolt. (4) The reducer and the roller shell are broken at the connection of the roller. (5) The fan box body fan -shaped plate is broken, and the gear that replaces the box or break is removed. (6) The 08 bearing of the 08 bearing of the reducer is ruptured (commonly known as the cow's nose rupture), and it is necessary to remove the box or the broken gear. (7) All the gears of the reducer are worn. After installation, you need to be used in accordance with the instructions before it can be used. After the failure, the reducer needs to replace all the gears and bearings.

Promotion of the main motor: (1) The lift motor is unable to run or the motor does not operate. To ensure that the voltage of the motor should be not less than 90%of the rated voltage, the power cable must be selected according to the instructions. Adjust the power to ensure that the difference between the three -phase voltage is less than ± 3%; check whether the fuse, the contactor and the various wiring heads are connected normally. Remove the brake wheel, remove the rear -end rust, and then install the debugging and return to the factory to repair it. (2) Sloping brakes. Adjust the brake gap 2 ~ 4mm, replace the brake ring (wheel), and regularly fuel injection of the bearings to ensure the flexibility of the axis of the machine. (3) The brake sounds over. Adjust the brake space of 2 to 4m m and replace the brake ring. (4) Power stick. Limit lines or leading lines should be bandaged in time to remove foreign objects in the stator; increase the capacity of the circuit breaker (air switch). (5) The brake ring is deacid, broken or loose. Replace the fan braking ring.

The reconstruction of the tube device and a shaft device and the middle shaft device: (1) The guide rope is broken. The guide rope is easy to be damaged. Except for cast sandhole or tangel breaks, other damage is purchased and replaced. (2) Limit rod card to death. Plastic surgery and kept telescopic, you can add lubricants if necessary. (3) Deformation of the rolled tube shell. Perform large repair and plastic surgery. (4) Steel wire ropes break the wire and break the stock. The steel wire rope is an important part of the gourd. According to the degree of use, the 1A warranty period cannot be used as the boundary. When the inspection is found that the fatigue wire of the steel wire rope and the disconnected stock should be replaced immediately in accordance with the prescribed standards. (5) Display abnormal noise at the fixed slide. After inspection, add an appropriate amount of lubricating oil to the sound of the sound. (6) The hits of the middle shaft device. Increase the adjustment of the pad to reduce the amount of dynamic.

Electric cars and running motor renovation: (1) Active wheel dental wear needs to be replaced with small car maintenance wheels. (2) The rotation bearing is worn or broken. (3) The car wallboard is curved and needs to be replaced. (4) The driver is bursting to replace the driver assembly. (5) Pay attention to the flat, or change the paper pad when installing the noise. (6) The running motor is required to replace the running motor or restart the motor.

The hook device transformation: (1) The transformation of the hook head is recommended to replace the piano and the suspender, and replace the deformable hook in time. (2) The hook is grinded out of the groove. It is recommended to replace the chain and piano, and timely replace the wear hook. (3) The hook shell is damaged. The hook shell is required. (4) The hook pulley is damaged. The hook pulley needs to be replaced.
