What is a bridge crane

Bridge crane is a lifting equipment that is horizontally suspended above workshops, warehouses, and material yards for material lifting. The following is a detailed introduction to bridge cranes by the manufacturer of Shandong bridge cranes:

1、 Basic Structure

A bridge crane is generally composed of a bridge (also known as a crane), a lifting mechanism, a trolley, a trolley moving mechanism, a control room, a trolley conductive device (auxiliary sliding wire), a crane main power conductive device (main sliding wire), and other parts. Among them, the bridge frame is the basic component of the bridge crane, consisting of the main beam and end beam, and is divided into two types: single main beam bridge frame and double beam bridge frame. The main beam is welded with tracks for the operation of the crane trolley. The control room is a crane control pod, also known as the cab, which is usually fixed at one end of the main beam, but there are also a few installed under the trolley to move with it.

2、 Working principle

The working principle of bridge crane mainly relies on the collaborative work of its various components. The lifting mechanism is used to vertically lift and lower objects, while the lifting trolley is used to carry a load for lateral movement; The bridge and the crane operating mechanism are used to move the lifting trolley and items longitudinally, in order to form a three-dimensional space for handling and loading and unloading goods within the span and specified height.

3、 Type and Characteristics

There are various types of bridge cranes, such as ordinary bridge cranes, simple beam bridge cranes (also known as beam cranes), suspended beam cranes, and explosion-proof bridge cranes. These different types of cranes have differences in lifting capacity, span, working speed, and application scenarios. For example, explosion-proof bridge cranes adopt explosion-proof measures in mechanical parts such as motor and electrical parts, as well as metal contact surfaces, to ensure the safety of use in explosion-proof environments.

4、 Application scenarios

Bridge crane is an important tool and equipment for achieving mechanization and automation of the production process in modern industrial production and lifting transportation. It is widely used in indoor and outdoor industrial and mining enterprises, steel and chemical industry, railway transportation, port terminals, logistics turnover and other departments and places. In the factory building, the bridge crane can fully utilize the space under the bridge to lift materials without being obstructed by ground equipment.

5、 Operation and maintenance

The operation of bridge cranes requires professional personnel and strict adherence to safety operating procedures. During the operation, attention should be paid to observing the operating status of the crane and the surrounding environment to ensure safety. At the same time, maintenance of bridge cranes is also very important, including daily maintenance, regular inspections, and troubleshooting. These measures can extend the service life of the crane and ensure its safe and reliable operation.
