In order to ensure the safety of port crane operation, Yuanwang has been reminding you to do a good job in equipment erection, pre work inspection and regular maintenance. In fact, in the operation process, you can achieve stable and safe effect by controlling the lifting speed.
The working speed of port crane includes: lifting speed, turning speed, luffing speed, etc. In the lifting operation, the lifting speed is the most important parameter, especially in the high-rise buildings, improving the lifting speed can improve the work efficiency, and at the same time, the lifting objects need to be slow in place, so the wide range of lifting speed change is the performance of excellent lifting performance.
The hoisting speed is not only related to the hoisting mechanism, but also to the ratio of the hook pulley block. The hoisting speed of 2 rope is twice as fast as that of 4 rope, and that of single rope is twice as fast as that of 2 rope.
In the hoisting operation, the speed of rotation and luffing is not required to be too fast, but it must be able to start and brake smoothly, realize stepless speed regulation, and frequency conversion control is ideal
In order to have a stable lifting speed, it is also related to the professional quality of the operators. Therefore, we must be careful in the selection of crane operators, and there must be no layman or half crane on duty.
