40 Ton Double Girder Overhead Crane with Winch Trolley

Double girder overhead cranes are also called double girder cranes and overhead cranes. The bridges run longitudinally along the tracks laid on the elevated bridges on both sides, and the trolleys run laterally along the tracks laid on the bridges, forming a rectangular working range. It can make full use of the space under the bridge to lift materials without being obstructed by ground equipment.

This kind of bridge crane is widely used in indoor and outdoor warehouses, factories, docks and open storage yards. It is mainly composed of bridge frame, cart running mechanism, trolley, and electrical equipment and so on. According to the frequency of use, it is divided into three working levels: A5-A8.

The crane can be equipped with grabbing devices such as hanging motor grabs and electromagnetic suction cups to meet the needs of lifting various types of materials.

3. Component:

40 ton Double Girder Overhead Crane with Winch Trolley is mainly composed of bridge frame, trolley, lifting mechanism, parts and cab room. The bridge frame adopts box-shaped main beam, which is automatically welded by submerged arc welding; the trolley conducts electricity using a new I-beam track cable conduction device; the hoisting mechanism can also be equipped with a safety device according to requirements. The cab room has a wide field of vision, and all the mechanisms can be operated in the operating room, making the work comfortable and flexible.

4. Applicable Environment:

40 ton Double Girder Overhead Crane with Winch Trolley equipped with hooks are suitable for lifting work in machining, assembly workshops, metal structure workshops, metallurgy and foundry workshops and various warehouses; Equipped with grab buckets, it is suitable for metallurgical, cement, chemical and other industrial sectors or open-air fixed-span handling of bulk materials.

Crane working class: A5 crane (For less frequent work, such as general machining and assembly workshops).

Crane working class: A6 crane (used for more frequent work, such as auxiliary lifting in metallurgical and foundry workshops).

5. The difference between electric hoist, winch and winch trolley

The working principle is basically the same.

Hoists are generally used for lifting small and small-tonnage objects. They are responsible for lifting and lowering heavy objects in the vertical direction. They are generally used with small-tonnage cranes. The crane models are: LDA, LH. They can be used together or alone. Just use I-beams. , Electric hoists generally lift heavy objects from above.

The winch is mainly used for hoisting objects and lifting heavy objects, and is commonly used in construction sites, docks and other places. It is generally used to lift heavy objects powered by fixed pulleys from below. It is generally used with elevators. It has a high load-bearing capacity and can withstand tens or even hundreds of tons of heavy objects, but it is usually large in size and inconvenient to carry.

The winch trolley refers to the mechanism that walks left and right on the crane. The trolley and the electric hoist work on the same principle, but are used for lifting large-tonnage objects. They are generally used with double-girder cranes and run on the upper rails of the two main beams. From above There are many crane models that can be used to lift objects: QD QE QZ, etc.
