I. Product Overview

Double Drum Industrial Electric Winch is a professional industrial device designed for applications requiring synchronous retraction and release of double ropes. It utilizes a single-motor reduction synchronous drive structure, ensuring consistent output for both wire ropes from the power source. This effectively avoids common issues found in traditional dual-motor solutions, such as uneven tension, synchronization errors, and complex maintenance.

This equipment is widely applicable to scenarios demanding high stability and synchronization, such as military and special vehicle outfitting, industrial automation recovery systems, and engineering equipment integration. It supports multi-parameter customization and is suitable for long-term stable operation as a system-level device.

II. Engineering Application Experience

In actual engineering projects, double-rope operation systems often face the following pain points:

• Dual-motor drive synchronization is difficult: Long-term operation easily leads to tension deviation.
• Rope management issues: Rope piling and tangling often occur during recovery, leading to high maintenance frequency.
• Complex control system: Multiple failure points reduce engineering reliability.

In relevant engineering projects, this Double Drum Industrial Winch has been used for dual-cable synchronous recovery and traction systems. Through the single-motor reduction synchronous drive method, it maintains consistency in double-rope operation even under long rope lengths and continuous working conditions. This significantly reduces system adjustment and maintenance costs caused by desynchronization and enhances overall equipment reliability.

III. Core Design and Technical Advantages

1. Single Motor Synchronous Drive Structure A single gear motor drives both drums simultaneously, achieving synchronization at the mechanical structural level. This avoids inconsistent tension caused by motor response differences or electronic control deviations, making it more suitable for industrial applications requiring synchronization precision and long-term stability.

2. Grooved Drum + Rope Arranger (Double Spooling Design) The drum surface features a grooved structure combined with a rope arranging wheel (guide) design. This ensures the wire rope is arranged orderly layer by layer during retraction and release, effectively reducing tangled ropes and piling, extending the service life of the wire rope, and lowering daily maintenance pressure.

3. Mechanical Limit Protection The equipment is equipped with mechanical upper and lower limit devices. These can be flexibly adjusted according to actual stroke requirements to effectively control the winch's working range, preventing over-winding or over-travel, and enhancing system operational safety.

4. Compact Structure, Easy System Integration The overall layout is rational and compact, occupying minimal space. It is easy to install inside various industrial equipment or systems, making it suitable for project-based equipment integration and non-standard custom applications.
