GB6067-1985 "Safety Regulations for Hoisting Machinery" requires that the outline ropes should be neatly arranged on the drum in order. The rope guide as a rope arranging device, which is defined as a device that enables the steel wire rope to be neatly wound around the drum at a prescribed interval.
If no rope guide, the steel wire rope will be squeezed and deformed into the gap at the end of the drum; the oblique lifting will cause the random rope, the deformation of the steel wire rope, and the wear between the steel wire rope and the drum shell.
The rope guides themselves cannot rotate. When the drum is rotated, it is wound along with the wire rope, and is moved by the thread groove in the axial direction. The wound wire rope is accurately introduced into and out of the spiral groove of the drum at any time, and the wire rope is discharged through the gap of the rope guide.
A single-layer winding electric hoist should be provided with a rope guide; when the rope guide is used, it should be ensured that when the hook is lowered and the wire rope has no other external force, the wire rope can still be freely discharged from the rope guide exit. For lifting and lowering rated load, the deflection angle of the steel wire rope to the vertical axis of the drum axis is ± 3 °, which can work normally. The rope guide prevents random ropes.
