Electric hoist rope guide the design and production

wire rope hoist rope guide works are similar, guide rope itself does not rotate. When the spool rotates, with the rope wound driven by the axial movement of the thread groove, to keep the rope is wound into precisely, the spiral groove leads to the roll, wire rope by the guide gap discharge. However, this form of guide rope in use relatively high failure rate. The reason is mainly in connection rod guide rope slide, guide rope and wire rope on the drum winding movement can not be synchronized due. In order to reduce the occurrence of such failure on the guide rope design forms a useful improvement.

Single-layer winding  Rope hoist  rope guide should be set; when using rope guide, you should be able to ensure that when the hook down, no other external force rope, wire rope rope guide can still freely from the outlet of the discharge, when the lifting, down load,  Wire rope  on the drum axis of the vertical angle of ± 3 °, to work properly.
No guide rope wound caused chaos rope, the rope ends into the roll gap will be compressional deformation; ramp causing chaos hanging rope, wire rope deformation, wire rope wear between the drum shell.
 
The role of reel lifting mechanism is used to winding wire, power transmission, and the rotary motion into linear motion. Roll surface is usually cut helical groove helix angle which is generally 3 ° -4 °, to increase the contact area of   wire rope, and to prevent friction between the adjacent wire, to improve the life of the rope. Since the roll out of the spiral grooves cut rope guide also features that make wire rope can be ordered. But often in the absence of other supporting institutional synergies, wound on the reel will jump rope spiral groove, making rope row chaos; sometimes ends of rope into the roll gap is compressional deformation; also have rope skipping Several spiral groove;
irregular arrangement, causes rope, roll wear deformation; short, this will affect the drum, the  Wire rope  used, thus shortening the life of the crane.
Fairlead novel design, simple structure, easy installation and maintenance quick, long life cycle, low failure rate, with practical features. As technology advances, the guide rope structure is also a corresponding increase, assembly, repair and replacement easier. Some parts began to use the strength and resiliency of high-strength plastic, instead of the previous cast iron materials, and also added a wear-reducing additive, roller and rolling friction between the rope, the wear of the wire greatly reduced.
