We provide overhead bridge crane in reliable quality and various types and specifications. Firstly, this is some basic information about the overhead bridge crane. It is available in both single girder builds and double girder builds. On the one hand, the single girder overhead bridge crane can be operated with one girder supporting a trolley and hoist. On the other hand, the double girder bridge crane depends on two bridge girders. Compared with single girder overhead bridge crane, double girder bridge crane can provide better headroom than a single girder crane.
Single girder bridge crane parameters:
- Load capacity: 1-25t
- Span: 7.5-31.5m
- Lifting height: 6-30m
- Lifting speed: 0.3-8m/min
- Hoist running speed: 20m/min
- Crane running speed: 20m/min
- Work duty: A3, A4
Double girder bridge crane parameters;
- Load capacity: 5-450t
- Span: 10.5-31.5m
- Lifting height: 6-24m
- Lifting speed: 2.1-11.5m/min
- Trolley running speed: 27-40m/min
- Crane running speed: 42-75m/min
- Work duty: A3-A7
Overhead bridge crane is a kind of lifting equipment for lifting material in the cross rack in the workshop, warehouse, and yard, etc. They are similar with bridges in the appearance because both ends are located in the tall cement columns or metal supports. The frame of the overhead crane can run along the track on both sides of the overhead frame which can make full use of the space under the bridge frame to lift the goods and not be hindered by the equipment in the ground. It is said that the overhead crane is the most widely used in the lifting appliances and it also has the largest number of lifting appliances.

The Components of Overhead Bridge Crane
Generally speaking, the overhead bridge crane components consist of several parts: bridges (also known as carts), lifting mechanism, trolleys, carts moving mechanism, control room, trolley conductive devices (auxiliary slide lines), main power conductive devices (main slip line) and other components.
Bridges: bridge frame is the basic component of overhead bridge crane. It is composed of the main girder, end beam, and walking platform. The main girder spans over the span which is composed of a box, frame, web, and circular pipe. The ends of the main girder are connected with the end beams, and there is a walking platform outside the two girders with safety rails. On the side of the cab, there is a truck transfer mechanism. On the other side, there is a device for supplying power to car electrical equipment which can be called the auxiliary sliding line. A guide rail is laid above the main beam for the trolley to move. The entire bridge crane moves along the workshop length direction under the dragging of the cart driving mechanism.

Lifting mechanism: the lifting mechanism is made up of a lifting motor, reducer, a drum, and a bake. The hoisting motor is connected with the coupling, the brake wheel, and the reducer. The output shaft of the reducer is connected with the winding drum of the winding wire rope. The other end of the wire is loaded with a hook. When the drum is rotating, the hook will rise with the winding of the wire rope on the reel. You also should know that the lifting cranes more than 15 ton, two sets of lifting mechanisms should be prepared which named the main hook and the auxiliary hook.
Trolley: The trolley is placed on the guide rail of the bridge and it can move along the width direction of the workshop. Generally speaking, the trolley is mainly welded by steel plates, which is composed of a small frame and its moving mechanism and lifting mechanism.
Control room: the control room is designed aiming to make more convenience to the operator. The control room is located on one side of the crane where the operator can see the whole situations insight without the obstacles.
Trolley moving mechanism, trolley conductive device and main power conductive devices are also the main components in the whole overhead bridge crane. These devices are equipped in the crane to ensure and improve the working conditions of the crane.
