Title:Black Nylon Material Split LBS Grooved Sleeves or LBS Shells

Breif introduction:

It is very expensive for drilling customers to customize a suitable drum for winch. So we design a kind of cover for drum,which is called LBS grooved shells or LBS groove sleeves.  We divide it into two parts that could be installed on the drum and instead of making a whole drum.

We can use a variety of materials to manufacture the sleeves. If the customer need a light material,you can choose nylon material.

Product material:

Carbon steel, alloy steel, cast steel, aluminum, all kinds of high-strength steel Q345, Q420, Q460, 15CrMo,20GrMo, 42GrMo, etc

Material standards: GB, AISI, ASME, ASTM, JIS DIN, NF, BS, EN ...

Classification societies certified: DNV, ABS, GL, LR, BV, CCS, RINA, NK, KR ...

Application conditions:

• the split-type LBS groove generally can be mounted on a smooth, grooveless drum-for for retrofit or where the drum needs to be replaced.
• The split -type sleeve system consists of a pair of outer casings that are bolted or assembled on a smooth light cylinder, so that the outer surface of the cylinder becomes a grooved form, and the split sleeve is composed of a spiral groove and a parallel groove, and the groove is formed. The design conforms to the specific rope structure, diameter and length.

Rapid customization:

• material
• the dimension of drum
• rope diameter
• pls provide us detailed drum drawing if possible
