Product Overview

The double drum winch system represents a significant advancement in crane component engineering. This product addresses the limitations of traditional single-groove designs by incorporating a dual-layer winding configuration that optimizes space utilization and reduces wear on the wire rope. The system's design is particularly suited for heavy-duty applications where reliability and longevity are critical.

Technical Innovations

The core innovation lies in the double folded wire rope groove design, which originated from international engineering practices. This system features a unique groove geometry where the majority of the drum circumference maintains parallel alignment with the flange end face. Only in a localized area does the cross-section intersect with the flange, creating a controlled bending point that minimizes stress concentrations.

Key technical features include:

• Welded flat drum construction for structural integrity
• Replaceable groove shell for cost-effective maintenance
• Optimized rope winding pattern for multi-layer applications
• Enhanced load distribution across the drum surface
