High-Capacity Heavy-Duty Crab Trolley Unit for Double Girder Overhead Cranes
1. Product Overview
Built for continuous, high-duty material handling, the Weiyuan DHR Heavy-Duty Double-Girder Crab Wire Rope Hoist serves as the primary lifting crab for double-girder bridge cranes. Featuring a robust 4-wheel box frame trolley, dual-drive travel motors, and heavy-duty European drive components, it ensures smooth travel, exceptional structural rigidity, and reliable performance across demanding industrial production environments.
2. Key Advantages & Technical Highlights
- Balanced Load Distribution: Rigid 4-wheel crab frame layout eliminates wheel binding and ensures uniform weight distribution across bridge rails.
- Enhanced Structural Durability: Heavy-gauge steel trolley frame with FEA-optimized welding withstands high dynamic dynamic loads and heavy duty cycles.
- Smart Monitoring & Protection: Includes an electronic overload cut-off, thermal motor protection, dual limit switches, and optional real-time load display.
- Precision Wear-Resistant Rope Guide: Polyamide/steel composite rope guide prevents wire rope tangling and ensures smooth spooling during side-pulling limits.
