Double Fold Rope Groove Luffing Drum Q355D Steel Right‑hand 40° For Lifting

Product Description

This luffing drum is manufactured from Q355D steel, fitted with 40° right-hand double-fold rope grooves to guide neat wire-rope arrangement and reduce rope wear. It features firm and reliable welding with no missed welds. Stress-relief treatment is carried out after welding to eliminate residual welding stress. With high structural strength and good deformation resistance, it is mainly matched with luffing lifting winch mechanisms for long-term stable operation.

Technical Parameter

Advantages

1. Q355D base material delivers good toughness and strong impact resistance under low-temperature conditions, adapting to complex site environments.
2. 40° right‑hand double‑fold rope grooves enable tidy wire‑rope winding, reducing rope disorder and squeeze wear to extend rope service life.
3. Strict welding quality control avoids missed welds. Post‑weld stress‑relief treatment lowers risks of later‑stage deformation and cracking.
4. Specially designed for luffing‑arm mechanisms, its force‑bearing structure fits luffing working conditions, providing stable load and improving overall equipment reliability.
