New Chinese style electric hoist
Heavy-Duty Intelligent Modular Lifting Crab for Double Girder Bridge Cranes
1. Product Overview
The Weiyuan New Chinese-Style Double-Girder Crab Hoist Trolley integrates an advanced modular box-frame layout with dual independent travel drives. Designed as the primary hoisting mechanism for medium-to-heavy double-girder overhead cranes, it features a low center of gravity, precision-ground gear transmission, and an intelligent condition monitoring system to deliver safe, smooth, and high-precision lifting performance.
2. Key Advantages & Technical Highlights
- Modular Box-Frame Construction: High-rigidity trolley frame with precision wheel bogies eliminates rail gnawing and ensures even wheel load distribution.
- Dual-Drive Inverter Travel: Independent drive motors on both sides provide smooth, synchronized trolley motion without wheel slippage or torque twisting.
- Intelligent Load & Cycle Diagnostics: Integrated black-box data recorder monitors total operating hours, load spectrum, and remaining safe working period (SWP).
- High-Durability Spheroidal Graphite Drum: Precision-machined rope grooves extend wire rope life and prevent premature rope wear.
