Gantry Crane Use Precautions

    The gantry crane is a kind of bridge type crane that is arranged on the two legs to form the mast shape. This crane runs on the ground track, mainly used in the open storage yard, dock, power station, port and railway cargo terminal and other places for handling and installation operations.

    Gantry crane hoisting mechanism, car running mechanism and bridge structure, and bridge crane is basically the same. As the span is large, most of the crane operating mechanism to use the drive to prevent the crane to produce skew operation and increase resistance, and even accidents. Gantry crane crane on the bridge to run, and some crane is a boom crane.

    The legs on both sides of the bridge are generally rigid legs; span of more than 30 meters, often one side of the rigid legs, and the other side through the ball hinge and bridge connecting the flexible legs, so that the gantry into a static system , So as to avoid the external load due to lateral thrust caused by additional stress, but also to compensate for the vertical deformation of the bridge gantry crane wind area, in order to prevent the use of strong winds under the taxi or tipping, equipped with wind measuring instrument and A crane gripper for interlocking with an operating mechanism.Gantry Crane

    The bridge can be either cantilevered at both ends and either cantilevered at either end or both ends to expand the operating range. Semi-gantry crane bridge at one end of the legs, the other end without legs, running directly on the high platform.Gantry Crane

    Precautions:Gantry Crane

1, lifting heavy objects, the hook wire rope should be kept vertical, are not allowed to drag the hanging objects. 2, the lifting of heavy objects should be accurate center of gravity, and tied firmly. There is an acute angle of the application pad mat.

3, the crane is not hanging from the ground before the crane can not do rotary motion.

4, to lift or down the weight, the speed should be uniform and smooth, to avoid rapid changes in speed, resulting in heavy objects in the air swing, dangerous. Falling heavy objects, the speed should not be too fast, so as not to fall when landing heavy objects.

5, the crane in the lifting of the case, try to avoid the swing arm. Must be lifted in the lifting of the case when the arm, the weight should not exceed 50% of the specified weight.

6, the crane in the case of heavy lifting, should pay close attention to whether there are obstacles around, if obstacles should try to avoid or clear.

7, under the crane arm can not have personnel to stay, and try to avoid the staff through. Gantry Crane
