Dual-Trolley Overhead Crane Solution for Automotive Welding Workshop

10t+5t dual-trolley overhead crane solution for a leading automotive OEM body welding workshop, enabling fast die-change for welding lines.

Project Background The automotive OEM's body welding workshop required frequent lifting of large welding dies (max. 8t per piece). Traditional single-hook cranes suffered from low die-change efficiency and poor positioning accuracy. Solution - 10t+5t dual-trolley overhead crane: main hook lifts dies, auxiliary hook assists positioning; synchronous operation improves efficiency by 40% - Variable frequency drive + anti-sway control system, positioning accuracy ±5mm - Hoisting mechanism with hardened gear reducer + disc brake for smooth, long-life braking - Compliant with FEM 1Am duty class, suitable for high-frequency operation (JC40%) Results - Die-change time reduced from 45 min to 28 min; production capacity increased by ~18% - Zero unplanned downtime over 18 months of operation - Solution replicated to 3 other production bases of the same client
