Drum structure design quality determines the quality of the whole system performance. Gantry lifting device adopts the structure of the latest, and adopted the latest technology on casting to improve the drum strength, hardness and wear resistance.
At present, most multi-layer winding drum is made with a rope slot. Because of the large amount of wire rope winding, so using the first layer of wire rope winding into the drum helical groove, the second cable is in the same direction of rotation winding into the inner formation of the spiral groove, wire rope contact situation has improved, and prevent the wire rope friction each other, so as to improve the service life of wire rope. Gantry crane reel to end a guard to prevent wire rope out outside the cylinder. The height of guard wire around the reel with remaining after 1 ~ 1.5 layer of wire rope allowance.
Has single winding and multi-layer winding drum. In gantry crane hoisting height is high, to reduce roll size, can be used on the surface of guide screw groove form or smooth drum, multi-layer winding, but steel wire wear faster.
steel wire rope fixed, in the past is fixed in the inner side
of the drum with press, so it takes up the inside space, reducing the length of
wire rope winding, and easy to cause the extrusion and friction interference of
wire rope, reduce the service life. This design to avoid the above shortcomings,
the wire rope to reel the lateral, again with pressure plate fixation. Thus,
although increased the size of the reel to the lateral, but the wire rope
winding length increases, the extrusion and friction of wire rope and reduce to
increase its life.
