Precautions for cantilever crane
The working strength of the cantilever crane is relatively light,which is composed of a column,a rotary drive device of the rotary arm and an electric hoist.The lower end of the column is fixed on the concrete foundation by anchor bolts.The rotary hoist is driven by a cycloidal pinwheel reducer to rotate the cantilever crane.The electric hoist moves left and right in a straight line on the cantilever I-steel and lifts heavy objects.The swing arm of the crane is a hollow steel structure,which has light deadweight,large span,large lifting capacity,and is economical and durable.Built in traveling mechanism,special engineering plastic traveling wheel with rolling bearing,small friction,light traveling,small structure size,especially conducive to lifting hook travel
What should be paid attention to when using the cantilever crane?
1.Zero the controller.
2.Irrelevant personnel are not in the work area.
3.The distance between the cantilever spreader and other equipment exceeds half a meter.
4.There are no untreated sundries in the working area.
5.The operating environment must be suitable for the operation.
6.The power supply line has no fault,and the disconnection alarm device is normal.
The operator shall not engage in the following work during operation:
1.Use authorized position limiter to stop.
2.Use the recoil brake.
3.Carry out maintenance inspection during the cantilever lifting operation.
4.Do not pass over the human body when working.
The above problems must be paid attention to during the use of cantilever crane to reduce the danger to a low level.
