Product structure:
It is composed of two parallel grooves and two crossed grooves in each circle of the winch drum.
The advantages of multilayer winding:
When the wire rope need to wind many layers, the LBS groove can fix the crossover point of the upper rope and the lower rope through crossed groove, which could control the crossover point and make it finished in the crossed groove. In the parallel groove,the upper wire rope can falls into the groove formed by two lower rope. It can form a stable structure between the upper wire rope and the lower wire rope. When the wire rope return to another sides,
Both ends’ bead flange can guide wire rope to climb smoothly and return. This structure make our LBS groove realize multi-layer winding and avoid teh messy rope. However, the ordinary spiral groove only make the first layer smoothly winding, but it can not guide the second layer convolve smoothly back, which is especially easy to cause messy rope problems.
The advantages of single layer winding:
According to your condition, since there is not pressure rope device, your movement is rely on the friction force between drum and wire rope. In order to prevent the wire rope from slipping, it is necessary to increase friction between the drum and wire rope. Compared to the spiral groove, the LBS groove have two parallel-line segment and two crossed -line segment, so the LBS have a larger friction, which could prevent wire rope from slipping.

Quality------IPQC method:
1. According to the audit list implementation process audit --- process the basic situation, not according to the product and change
2. Process operation inspection --- materials, tools, accessories, methods, personnel to confirm
3. The first thing to confirm the inspection - according to the product and other, technology, equipment, software, parameter inspection
4. Record --- real, clear and timely
5. Feedback mechanism between the various processes --- timely feedback related information
6. Early warning mechanism works
7. Nonconforming product control --- identification, isolation, differentiation placement, statistical analysis
8. Material inputs - the correct material, at the right time, into the right product, and timely and accurate records to facilitate the traceability
9. Product standards --- process standards, functional requirements
10. Sampling inspection of each process output --- to confirm the process is stable, with sufficient capacity, product qualified
