The New Type Double-Trolley Electric Hoist Bridge Crane is an advanced overhead lifting solution developed by Henan Mine, designed for industrial applications requiring heavy lifting capacity, operational flexibility, and high precision. Unlike conventional single-trolley cranes, this model features two independent trolleys operating on a robust double-girder bridge structure. Each trolley is equipped with a compact, high-performance electric hoist (European-style crab hoist), enabling the crane to handle two separate loads simultaneously or work in perfect synchronization to lift extra-long, oversized, or unbalanced workpieces such as steel pipes, concrete beams, large transformers, and ship sections.

The new type of double-trolley electric hoist bridge crane uses a new type of electric hoist as the lifting mechanism, with dual lifting speeds and variable frequency speed regulation during operation. Two independent trolleys share the same track and can operate independently or in coordination. They can not only independently transport materials of different specifications but also precisely lift and balance long materials through synchronous control

Adopting a lightweight, modular, and parametric design, this new type crane incorporates advanced variable frequency drive (VVFD) technology, integrated three-in-one transmission, and a suite of intelligent features—including anti-sway, inching, and zero-speed hover—ensuring smooth operation, energy efficiency, and superior safety. It is widely used in heavy machinery workshops, steel plants, shipyards, wind turbine assembly facilities, warehouses, and power plant maintenance bays.

It is applicable to places such as mechanical processing workshops, steel structure factories, pipe warehouses, assembly workshops, etc., and is mainly used for lifting and transporting long-sized goods such as steel pipes, profiles, and prefabricated components, as well as goods at multiple points and in multiple batches.

Application Scenarios – New Type Double-Trolley Electric Hoist Bridge Crane The New Type Double-Trolley Electric Hoist Bridge Crane is widely used across heavy industries where extra-long, heavy, or unbalanced loads require flexible and precise lifting solutions.

1. Steel & Pipe Manufacturing Yards – Lifting and transporting long steel pipes (up to 50 meters), large structural steel beams, thick steel plates, and heavy rebar bundles. Two trolleys working together grip both ends of a long pipe for stable, balanced transport without bending or damage, while independent operation allows one trolley to load raw coils as the other unloads finished products.

2. Precast Concrete & Construction Material Plants – Handling extra-long concrete beams, bridge segments, concrete pipe piles, utility poles, and precast wall panels. Synchronized operation ensures safe lifting of long, brittle concrete components from multiple support points, preventing cracking or stress damage.
3. Heavy Machinery Workshops & Assembly Lines – Positioning large components such as turbine shafts, generator rotors, wind turbine blades, transformer cores, large press frames, and mining equipment. Independent trolley operation allows one trolley to position components for assembly while the other fetches the next part, increasing throughput.

4. Shipyards & Marine Construction – Moving large ship sections (bow, stern, midship blocks), propeller shafts, rudders, engine housings, and heavy deck machinery into position. The double-trolley configuration provides balanced lifting for asymmetrical or irregularly shaped marine components, essential for dry dock assembly.

5. Railway & Locomotive Maintenance Facilities – Lifting long rail tracks, complete locomotive chassis, railcar bodies, heavy wheel sets, and traction motors for repair and replacement. One trolley can service one end of a railcar while the other trolley services the opposite end, reducing maintenance turnaround time.
