There are many types of CNS cranes, and the objects they lift are diverse. However, they all have some basic and generally applicable stability technical requirements.
There are many types of CNS cranes, and the objects they lift are diverse. However, they all have some basic and generally applicable stability technical requirements.
1.Before closing the main power supply, all controller handles should be set to zero position.
2. Before driving, it is necessary to ring the bell or give an alarm. When approaching people during operation, a continuous ringtone or alarm should also be given.
3.When the crane driver takes over the shift, he should inspect the brake, hook, wire rope and stabilizing device. If abnormal performance is found, it should be eliminated before operation.
4. The driver of each crane must undergo training, pass the assessment and hold an operation certificate before being allowed to operate.
5.When the crane operating outdoors on the track finishes its work, it should be anchored. When the wind force exceeds level 6, work should generally be stopped and the crane anchored. For portal cranes operating along the coast, when the wind force exceeds level 7, work should be halted and the cranes anchored.
6.When a sudden power outage occurs during work, all controller handles should be returned to the zero position. Before resuming work, it is necessary to check whether all the crane movements are normal.
7. The main power supply can only be closed when it is confirmed that there is no one on or around the small crane. If the power circuit breaker is locked or marked with a sign, it should be removed by relevant personnel before the power is closed.
8. Operations should be carried out in accordance with the command signals. Upon hearing the emergency stop signal, no matter who gives it, it should be executed immediately.
Common knowledge about cranes
1.The user unit should establish the necessary rules and regulations for the inspection and maintenance, regular inspection, operation, stability procedures and shift handover systems of cranes and equipment.
2. It is necessary to register each crane one by one and establish equipment files. The contents of the archives should include product qualification certificates, quality certificates, historical technical inspection reports, records of major repairs, changes in original design performance and major accidents, etc.
3. Enterprises should appoint full-time or part-time engineering and technical personnel to be responsible for the management of cranes and equipment based on their types, quantities and complexity.
The inspection of crane structural components shall be carried out in accordance with the following procedures
1. Daily inspection: The crane should undergo a daily inspection every 80 hours of operation. When changing shifts, the crane driver should check the tightness of the bolts at each connection point. If any are loose, they should be tightened in time.
2. When the crane makes abnormal noises, has experienced misoperation, or when the stability protection device of the crane malfunctions, etc., an inspection should be carried out.
