Split Type Spiral Groove Drum Sleeve Q355D Steel Left-hand For Lifting

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.

Technical Parameter

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
