Title: LBS Grooved Drum 100mm-10m For Petroleum Drilling Equipment & Construction Cranes
Brief intoduction about LBS system:
When using drilling equipment, you will find that the wire rope is often not evenly wound on the drum, so the wire rope is seriously worn or even scrapped quickly. LBS technology is a rope winding technology, which solves the problem of rope mess and rope bite in the process of winding.
LBS grooved drum:
So when you face the situation where exist mess& chaos of wire rope spooling, you can choose LBS grooved drum that could make the rope sit tidily next to each other. Besides, in multilayer spooling, LBS grooved drum can make each layer to ride cleanly onto the layer beneath.
|LBS grooved sleeves:|
Compared to LBS grooved drum, the sleeves can be easily installed on large reel if your reel can not be replaced. When you face the situation that if you replace the drum, you have to pay a lot. however, the LBS split -sleeves syatem can not only ensure that wire rope wrapped aroud a hoist drum in multilayers continues to spool totally smoothly, but also avoid your extra spending.
Integral rope groove drum: rope drums with grooves cut directly into them (with or without bolted or welded flanges, as required).Winch drum with flange, the LBS groove is cut directly into the body of the drum, according to customers’ requirements, the flanges are either welded or screw-bolted. groove geometry is determined by rope construction, diameter and length, and by application. the drum has the required mounting dimensions for the actual operating conditions.
LBS system design advantages:
1. it has obvious advantages in multilayer spooling, if your winch need multilayer spooling, LBS system is a good choice.
2. it has a special grooving design-- two parallel groove section and two groove section, which guarante multilayer spooling and aviod mess of wire ropes.
3.Lower the rope damage, extend the rope life.
It is easy to find our LBS system on cranes of all types cranes on oil rigs and ships construction cranes, tower cranes and more.
|Q1||Can i install LBS split sleeves on any type of cable drum?|
|Subject to compliance with the techincal requirements of a LBS system , any wire rope winch system can be retrofitted with a LBS groove.|
|Q2||What minimum preload is necessary for the LBS groove?|
|The preload is the load on the cable at the cable drum. As a rule, it should be at least 2% of the breaking load or 10% of the working load. at the same time, however, the provision must also be made for the safety coefficient and the design of the cable.|
|Q3||What material can a LBS groove be made of ?|
|Steel grade Q345B is used as standard. however, special steels such as Q420, Q460, 15CrMo,20GrMo, 42GrMo, etc
