Өрмекші кранды таңдау және күнделікті ақауларды жою үшін жалпы мағына

There are many small crawler cranes on the market today, large and small, and they produce similar models but do vary in quality and price. So in the face of such a situation, how do we choose manufacturers for transaction cooperation? Let’s talk about the common sense of selecting small spider crane products and daily troubleshooting methods.

Things to check before choosing a spider crane:

1. The driver of the өрмекші кран should test the vehicle in person to see how smoothly the crane operates and whether there are any abnormal noises in the parts.

2. Check the swing degree of the boom, the flexibility of the winch, the sinking and deformation of the crane legs, etc.

3. The maintenance technician should check whether the frame (especially the rotation) is torn or deformed (it is recommended not to buy if there are traces of welding), steering gear, brakes, engine, gearbox, hydraulic system, etc.

Daily troubleshooting and maintenance methods for spider cranes:

1. Coil heating: If the suction force of the electromagnet is too large, adjust the pressure to make it suitable. If the silicon steel sheet is not tightly fixed between the dynamic and static parts, it should be re-fixed tightly. If the coil voltage does not match the grid voltage, check Make sure the voltage does not exceed the rated voltage value for clear reasons.

2. The electromagnet makes loud noise when working: the magnet is overloaded, there is a gap in the contact surface of the magnetic flow path, and the coil voltage is too low or too high, which will cause the electromagnet to make loud noise when working. At this time, the electromagnet should be checked, the spring tension should be adjusted, and the vibration should be eliminated. , Check the gap between the contact surfaces of the static magnets, and check and eliminate the faults of too low or too high power supply voltage.

3. The electromagnetic brake coil is severely heated: the cause of this fault may be that the movable part of the electromagnet magnetic circuit is dirty, skewed and stuck, causing the static iron core to not be sucked in place, or the silicon steel sheet is not pressed tightly, a short circuit between the steel sheets or a short circuit on the yoke surface. . Deflections and jams should be repaired and adjusted, dirty oil should be cleaned or broken parts should be replaced.

SEVENCRANE Company has strong technical research and development capabilities and a variety of welding and CNC processing equipment. It can individually design various spider cranes according to user requirements to meet the needs of different industries.

At present, the small spider cranes produced by SEVENCRANE are mainly used in small space situations such as automobile engine workshop equipment inspection and maintenance, electric power inspection and maintenance, chemical workshop inspection and maintenance, building curtain wall installation, construction of high-speed rail stations, and the cemetery stone industry.
