50/25 Ton Double Girder Cree

Le 50/25 Ton Double Girder Overhead Crane is a heavy-duty industrial electric overhead traveling (Eot) crane engineered for high-capacity, dual-load lifting operations. Designed with a main lifting capacity of 50 tons and an auxiliary lifting capacity of 25 tonnes, this double girder crane perfectly balances heavy-load handling and flexible light-duty operation. It adopts a robust box-type double girder structure, compliant with international industrial crane standards, and features stable operation, high working efficiency, wide adaptability, et longue durée de vie. This crane is widely applied in heavy manufacturing workshops, aciéries, usines de transformation de machines, entrepôts, and industrial yards for material handling, installation d'équipement, and heavy cargo transfer tasks.

Classified as A5-A6 working duty, the equipment is suitable for continuous, high-frequency industrial operation, capable of tackling both long-term heavy-load lifting and precise small-tonnage handling, effectively meeting diverse production and logistics demands of modern industrial enterprises.

Conception structurelle de base

1. Optimized Double Girder Structure

The crane adopts a high-rigidity double box girder welded structure, processed via integral welding, stress relief annealing, et technologies d'usinage de précision. This structural design uniformly disperses heavy load pressure, effectively avoiding structural deformation and shaking during high-capacity lifting. Compared with single girder cranes, the double girder configuration greatly improves overall stability, load-bearing performance, et la sécurité opérationnelle, supporting larger spanning distances and higher lifting heights. The streamlined girder design also reduces wind resistance and self-weight energy consumption, realizing lightweight and high-strength structural integration.

2. Dual Lifting Mechanism

Equipped with independent main and auxiliary hoisting systems, the 50-ton main hoist undertakes heavy-duty cargo lifting, while the 25-ton auxiliary hoist is responsible for auxiliary lifting, fine positioning, and light-load rapid handling. The dual-hoist collaborative design solves the problem of single-functional limitation of traditional cranes, enabling switching between heavy-load stable operation and light-load efficient operation freely. The two lifting systems operate independently without mutual interference, which greatly improves the flexibility and comprehensiveness of on-site lifting work.

3. Reliable Traveling System

The crane’s end carriage and traveling mechanism adopt high-precision assembly and thickened anti-wear traveling wheels, matched with frequency conversion driving motors. The traveling operation is smooth, with no impact or deviation, and the wheel-track fit is precise to reduce track wear and operational noise. The whole traveling system features strong bearing capacity, faible taux d'échec, et longue durée de vie, adapting to long-distance and frequent reciprocating operation in large-span workshops.
