Guide wire itself can not be rotated, when the drum rotates, with the wire rope down the wire machine, by the outer thread groove to push along the radial move, at any time and anywhere the coiled wire rope is precisely introduced and drawn to the spiral groove of the drum, the wire rope is discharged from the vacancy of the guide wire. The guide wire nut is cut into 5 pieces, which are connected by the connecting strip steel and the guide wire plate. The wire rope is extended from inside and outside the long V-shaped groove of the guide wire plate. Guide rope nut and drum rope groove teeth, drum rotation to push the guide rope nut to move horizontally, to ensure that the wire rope in the drum rope groove is not messy. The guide rope plate of the multi-functional jack supplier moves horizontally to both sides of the drum. When it reaches the limit part, the positioning rod assembled on the drum shell moves together and reaches the limit part to move the limit switch installed on the main motor and has positioning effect. Advantages of rope guide: to prevent wire rope chaos, to ensure that all the normal work of the electric hoist; Reliable pressure rope, so that the wire rope can not jump from the groove; Reduce the damage between wire rope, increase the service life of wire rope and drum; Pneumatic jack supplier and server limit switch with each other, to avoid the king of lifting hook head too low, promote the use of staff according to the standard of actual operation, reduce the occurrence of safety accidents; Easy maintenance and maintenance, strong tolerance.
