[0010] Preferably, one end of the slider is provided with a threaded groove.

[0011] Beneficial effects

[0012] This utility model provides a hoisting device for chemical equipment. The device features a structure designed for the stable hoisting and movement of chemical equipment. The equipment is placed in the lower part of a gantry frame and secured by two pairs of hooks. The hooks are manually tightened to prevent them from slipping. An adjustable motor drives the connecting rope to wind up the rope rollers, lifting the equipment. The operator can move the gantry frame by holding a pair of handles and using the casters. Existing devices can stably hoist chemical equipment; the four simultaneously lifting connecting ropes increase hoisting stability, and the hooks can be locked to prevent the equipment from falling, increasing safety.
