Overhead Crane is widely used in factories, warehouses, harbors, etc. This article will give you an in-depth understanding of the overhead crane's definition, structural composition, design points, functional features, and the difference with Gantry Crane. If you don't know how to choose the right Overhead Crane or want to know its price range and application areas, then this article will be your ideal guide.
Overhead Crane is a lifting equipment for lifting materials over workshops, warehouses and yards. Because of its two ends are located in the concrete column or metal support, the shape is like a bridge, so it is called a overhead Travelling crane. Overhead Crane bridge along the track laid on both sides of the elevated longitudinal run, you can make full use of the space under the bridge lifting materials, not and the ground of the conflict between the equipment. It is also the most widely used, the largest number of a lifting machine.
Overhead Travelling crane is mainly used for material handling and have a variety of functions to efficiently accomplish the loading, unloading, handling, and stacking of goods.
The bridge crane consists of main girder, end girder, trolley running mechanism, Overhead Travel Mechanism, hoisting mechanism, rail, cab, walking platform and other parts. The functional characteristics of each part are as follows:
Weihua, as a professional bridge crane manufacturer and customizer, has multiple different types of bridge cranes. If you still don't know which type of overhead crane can enhance the productivity of your factory. Then the following article will bring you a comprehensive understanding of the different types of bridge cranes and their application scenarios.
Double girder overhead crane：The double girder overhead crane configuration consists of two bridges, two end cars and one or two trolley hoist assemblies. The trolley hoist travels on tracks mounted on top of the bridges. Typically double girder overhead travelling cranes are suitable for use with lifting capacities from 5 to 200 tons.
Single girder bridge crane：A single girder bridge crane configuration consists of a single bridge, two end trolleys and a trolley hoist. Typically, single girder overhead travelling cranes are suitable for lifting capacities of1-32tons.
European Double Girder Bridge Crane：European double bridge crane is an important material handling equipment. It is also known as a double girder eot crane. It is widely used in industrial and mining enterprises, steel and chemical industries, etc. Users prefer to choose it for its simple structure, good stability, smooth operation, and large lifting capacity.
QB Explosion-proof Bridge Crane：Double beam explosion-proof bridge crane is one lifting equipment specially designed for use in environments with flammable, explosive gas or dust. The overall performance of the crane complies with the provisions of the standard JB/T5897-2006 "Explosion-proof bridge cranes". The explosion-proof marks are ExdIBT4 and ExdICT4, respectively.
QZ Grab Bucket bridge Crane：QZ Grab Bucket Overhead Crane is a highly efficient lifting equipment specialized in gripping bulk materials. It occupies an important position in the field of material handling. With its unique design and functions, it meets the needs of bulk material loading and unloading in many industrial scenarios.

Travelling overhead crane bridge along the track laid on both sides of the elevated longitudinal run, you can make full use of the space under the bridge lifting materials, not and the ground of the conflict between the equipment. for material handling in limited spaces. In contrast, gantry cranes consist of an A-type or rigid outrigger-supported beam structure and typically run on ground tracks or wheels. Mainly used for material lifting in large construction sites, handling of wind power project components, and use in machinery manufacturing plants, etc.
