Compared with cordless groove (smooth) drum and helical groove drum, LBS grooved drum has obvious advantages in multilayer spooling. It can be widely used in the heavy lifting and compact working conditions.
LBS grooved winch drum advantage:
- Each one circle layer of the grooved drum has two parallel groove section and two groove section
- Make wire rope spooling more smooth and uniform distribution of load between each layer
- Prevent cross &mess in rope spooling working happening
- Lower the rope damage, extend the rope life
Quality assurance----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
