Product Introduction

double girder trolley electric hoist

The Double Girder Trolley Electric Hoist is a high-capacity, industrial-grade lifting solution designed for integration with double girder overhead cranes. This robust system combines a powerful palan électrique mounted on a motorized trolley that travels along the crane’s twin bridge girders. It is engineered for heavy-duty applications requiring high lifting heights, precise load handling, and exceptional reliability in demanding environments such as steel plants, fabrication shops, entrepôts, and foundries. By optimizing the workspace and providing superior hook approach, it maximizes productivity and operational safety.

FAQ: Double Girder Trolley Electric Hoist

Q1: What is the main difference between a single girder and a double girder hoist system?

A: The key difference is structural. A single girder hoist runs under a single beam, which limits its capacity and hook height. A double girder hoist runs between two top-running girders, offering higher capacity, better hook approach, greater lifting height, and is built for more intensive, precise work.

Q2: Can the hoisting and travelling speeds be adjusted?

A: Yes. While dual-speed is standard, we highly recommend Variable Frequency Drives (VFD) for precise control. VFDs allow for soft starts/stops and infinitely variable speed adjustment, which is crucial for handling delicate loads or for precise positioning.

Q3: What safety features are included as standard?

A: Standard safety features typically include an upper/lower limit switch, an overload limit device, a dual braking system (electromagnetic + mechanical), and emergency stop buttons on the pendant. Additional safety options like anti-collision systems and rotational hook blocks are available.

Q4: How is the hoist maintained and serviced?

A: Maintenance is straightforward. Regular checks include visual inspection, verifying brake function, checking wire rope for wear, and ensuring limit switches operate correctly. We provide detailed maintenance manuals and offer service contracts for periodic professional inspection.

Q5: Can this hoist be customized for a specific application?

A: Absolutely. We offer a wide range of customization options, including special lifting heights, capacities, speeds, voltage, and specific duty cycles. We can also provide special hooks, galvanized finishes for corrosive environments, or explosion-proof versions.
