Parts Of Crane

Code of safe use
- In the process of work, the operator should concentrate on, before lifting idling, then lifting, such as found lifting things tied not tight, should be re-tied.
- The use of bridge crane lifting things, not from the head over, in the operation, can not repair, check, refueling and rub parts, once the fault, to stop immediately.
- The safety device, braking mechanism, sound and light, signal and interlock device of the equipment must be sensitive and intact.
- After the completion of the operation, we need to stop the equipment in the corresponding position and lift the lifting hook into place. No heavy objects shall be suspended from the lifting hook. Put all the controllers and joysticks in zero position, pull off the power switch, and lock the cab door.
- More importantly, the live part should be grounded to avoid electric shock.
Maintenance
The maintenance of bridge erection machine is not to say that once a month to complete, usually also need to pay more attention to the inspection of equipment. The staff needs to pay attention to, when checking the quality of the lifting equipment must start before starting the inspection, and to see every detail of the equipment. Especially the hoisting equipment of the wire rope to pay more attention. This plays a vital role in the application of lifting equipment. In addition to the daily inspection to carry out maintenance, the correct operation of lifting equipment is the key. Finally, devices can last for years if users pay special attention to simple operational problems. This will not only bring security technology for you, but also in the financial problems to save, thus visible, kill two birds with one stone.
Dismount
