30 Tonnellata di gru a ponte a doppia trave

30 ton double girder overhead crane is a heavy-duty industrial material handling equipment designed for high-frequency, large-load lifting operations in modern factories, officine, magazzini, and steel processing plants. Compared with single girder overhead cranes, the double girder structure delivers superior stability, higher lifting height, durata di servizio più lunga, and stronger load-bearing capacity, making it the preferred lifting solution for 30-ton heavy-load industrial scenarios. Engineered to comply with international industrial safety standards, this overhead crane combines robust mechanical structure, intelligent control system, and comprehensive safety protection devices to ensure efficient, stabile, and safe long-term operation.

Core Product Overview

The 30-ton double girder overhead crane (also known as 30-ton double beam bridge crane) consists of a box-type bridge frame, carrello da viaggio, electric hoist/winch mechanism, longitudinal traveling system, and complete electrical control system. The dual parallel box girders adopt high-strength Q355B steel welding technology, which effectively reduces structural deformation and enhances overall rigidity, even during long-span and full-load working conditions. This crane can realize three-dimensional movement: longitudinal traveling along workshop rails, transverse traveling of the trolley on the main girder, and vertical lifting of goods, covering a full range of material handling needs for heavy industrial production.

Available in standard working classes A5, A6 and A7, it adapts to different working intensities — A5 for general intermittent industrial handling, A6 for medium-frequency heavy-duty operation, and A7 for high-intensity continuous working scenarios such as steel mills and heavy machinery manufacturing.

Eccezionali vantaggi del prodotto

1. Ultra-Stable Double Girder Structure

The optimized double box girder structure greatly improves the overall stability and load uniformity of the crane. It effectively avoids shaking and deflection during 30-ton heavy-load lifting and long-distance traveling, ensuring accurate positioning of goods. Different from single girder cranes with limited load and height, this double girder design supports higher lifting heights and larger working spans, fully meeting high-standard heavy industrial production demands.

2. Durevole & Design a bassa manutenzione

The main girder adopts integral welding and stress relief treatment, with strong compression resistance and deformation resistance. All core components such as motors, riduttori, and brakes use international brand accessories, with stable performance and long service life. The standardized modular structure simplifies daily maintenance and replacement of spare parts, greatly reducing long-term operation and maintenance costs for enterprises.

3. Flessibile & Operazione precisa

Equipped with an intelligent frequency conversion control system, the crane realizes stepless speed regulation, avoiding sudden start and stop that cause cargo shaking. Multiple operation modes are optional to adapt to different working environments: remote control for convenient ground operation, pendant control for precise short-distance operation, and cabin control for long-time high-intensity work. It can match various accessories such as electromagnetic chucks, grab buckets, and spreaders to realize multi-scenario material handling.

4. Sistema completo di protezione della sicurezza

Safety is the core design of the 30 carroponte bitrave da tonnellata. It is equipped with a full set of safety protection devices: overload limiter to prevent overloading operation, upper and lower limit switches to avoid hook collision, emergency stop button for sudden danger, brake failure protection, phase sequence and loss-of-phase protection, and rainproof and dustproof devices for outdoor/harsh workshop environments. All safety configurations comply with ISO and FEM industrial standards to maximize the safety of equipment, goods, and operators.
