The operation method of load turn crane

When using the crane, it will also involve several different methods of turnover operation, which have different emphases and attentions. The electric hoist has compact structure, and the electric hoist with the motor axis perpendicular to the drum axis adopts worm gear transmission device. Its defects are: large length scale, large width scale, bulky structure, low mechanical efficiency, difficult processing and so on. The hydraulic system is controlled in two layers, and the overflow regulating valve and magnetic contact pressure gauge can accurately control the pressure. Low voltage control is selected for the electrical control part, which increases the safety of the distribution system. We also need to know something about this in order to better master the operation of the crane and complete all kinds of related operations.

The operation method of  load turn crane  mainly includes three methods: somersault, swim somersault and belt somersault. The electric hoist has compact structure, and the electric hoist with the motor axis perpendicular to the drum axis adopts worm gear transmission device. Its defects are: large length scale, large width scale, bulky structure, low mechanical efficiency, difficult processing and so on. The hydraulic system is controlled in two layers, and the overflow regulating valve and magnetic contact pressure gauge can accurately control the pressure. Low voltage control is selected for the electrical control part, which increases the safety of the distribution system. Among them, rollover is mainly for objects that are not afraid of collision. During this operation, the lifting hook of the crane must be lifted vertically and always maintain this state. When the weight exceeds the supporting point, it will turn over naturally.
The operation is used for the turnover of flat objects. When the objects are lifted, there will be large ups and downs of the swing. When the swing reaches the value, the objects will fall quickly in an instant. The electric hoist has compact structure, and the electric hoist with the motor axis perpendicular to the drum axis adopts worm gear transmission device. Its defects are: large length scale, large width scale, bulky structure, low mechanical efficiency, difficult processing and so on. The hydraulic system is controlled in two layers, and the overflow regulating valve and magnetic contact pressure gauge can accurately control the pressure. Low voltage control is selected for the electrical control part, which increases the safety of the distribution system. The operation of turning over is to lift the object, then fall down until the crane steel wire rope (composed of steel wire, rope core and grease) is tightened, and then drive the object in the direction to be turned over.
Because the object will not be damaged in the process of operation, this method is most widely used, but we should also pay attention to the cable-stayed point of view in the overturning operation of the crane.
