Split Type Spiral Groove Drum Sleeve Q355D Steel Left-hand For Lifting
Product Description
This split spiral groove drum sleeve is made of Q355D steel, with segmented milled left-handed spiral rope grooves that form a complete barrel via bolt assembly. The workpiece surface is sprayed with anti-rust primer, delivering outstanding low-temperature toughness to effectively reduce wire rope abrasion. The split structure enables easy disassembly and assembly, greatly lowering on-site maintenance and replacement difficulty, compatible with all kinds of lifting winch mechanisms.

Advantages
- Q355D base material resists low-temperature impact, suitable for outdoor lifting in cold regions
- Split bolt splicing eliminates integral disassembly, cutting maintenance and replacement costs
- Precision left-handed spiral grooves realize neat rope winding to avoid tangling and abrasion
- Surface spray primer provides basic anti-rust protection and slows steel corrosion
Matters Need to Attention
- Tighten all connecting bolts diagonally and evenly during assembly to prevent barrel deformation
- Only use left-handed wire ropes to avoid mismatched friction between grooves and cables
- Repair damaged primer coating in time; inspect paint surface regularly for outdoor equipment
- Overload operation is forbidden; routinely check groove wear and bolt tightness
