PRODUCTS & CASES

The CD/MD series electric wire rope hoist is an upgraded industrial lifting device optimized to solve common defects of traditional hoists, including hook over-travel, wire rope disorder, rope guide damage, gearbox oil leakage and frequent electrical failures. Adopting upgraded structural design and optimized accessory matching, this series hoist greatly improves overall stability, safety and operational reliability, delivering more consistent and trouble-free lifting performance for long-term industrial service.

Core Structural Upgrades & Technical Improvements
           1. Reliable Counterweight Limit Protection
           Equipped with a high-stability counterweight limiting device featuring simple structure and high sensitivity. It effectively avoids hook over-travel risks caused by limit switch failure or mechanical abnormality, providing dual safety protection for vertical lifting travel.

           2. Anti-Disorder Rope Guide System
           The upgraded specialized rope guide ensures neat, smooth and ordered wire rope winding during lifting and lowering cycles. Even when the hook is under no tension, the rope can still discharge smoothly without stacking or entanglement, completely solving the traditional rope disorder problem and improving overall operation safety.

           3. Integrated Split Rope Guide Nut
           The rope guide nut adopts an integral split structure with automatic tension adjustment function. It features strong wear resistance, high structural toughness and long service life, reducing frequent replacement and lowering later maintenance costs.

           4. Failure Rate Optimization
           Targeted structural optimization greatly eliminates common faults such as rope guide cracking, gearbox oil leakage and circuit malfunctions. The whole machine runs more stably with fewer breakdowns, significantly improving continuous working efficiency and reducing downtime losses.

• Higher Safety: Multi-layer limit protection system effectively prevents over-hoisting and mechanical accidents.
• Neat Rope Operation: Anti-disorder rope structure ensures smooth wire rope arrangement without entanglement or jamming.
• Low Maintenance: Wear-resistant components and optimized structure reduce daily inspection and replacement frequency.
• Stable Performance: Adaptable to frequent and continuous light & medium-duty industrial lifting scenarios.
