The main role of the bridge crane is to mobilize the lifting equipment, also known as "overhead crane". He is a bridge crane, through the hoisting mechanism can be in the horizontal and vertical two mutually vertical space for movement, he is widely used in the industrial and mining industries, characterized by high reliability, and the bearing capacity is very large, relatively simple manufacturing. His main components include running bridge, lifting trolley driver's cab and electrical equipment and other structures, his appearance looks like a flat bridge, his lifting mechanism is used to transport goods in the vertical direction, and his lifting trolley is used to move horizontally, coupled with the rotation, so that he can be in the space of the head of the handling and loading and unloading of goods.

Working characteristics of overhead cranes

The working characteristics of the overhead travelling crane are intermittent and cyclic, and the purpose of transporting goods is achieved by moving the goods in space with hooks or other lifting devices. Here we talk about the working characteristics of the crane from the safety point of view.

1, because the structure of the crane is large and complex, in the work of several different directions at the same time, which makes it difficult to operate.

2, because we lift a variety of items, the weight is also a great change, so we need to design different hooks and lifting devices.

3, the structure of the crane is generally very bulky, he needs tracks and wheels, the working space is relatively large, so once the accident occurred, the scope of his influence is also quite large.

4, the working environment of the bridge crane petrochemical enterprises, ports, mining, construction sites, etc., because of a variety of different environments, we need to adapt to a variety of different harsh environments in the design.

5, the bridge crane in the work we need more than one person to cooperate, the operating room in the head of the driving staff, as well as the lower side of the cargo handling personnel, which makes everyone need to cooperate with each other, coordinate the work, the site staff to have the ability to deal with emergencies, to avoid major accidents.

The development direction of bridge cranes

With the development of industry, bridge cranes are also developing, becoming more and more high-speed, large-scale and intelligent. High-speed refers to the hoisting speed has been increased to 12m/min, the big car running speed to 80m/min. large-scale refers to the world's largest crane whose weight has reached 550t. and intelligent refers to the installation of advanced machine electronic control configuration, so that he is able to frequency speed control, detection means have become more advanced, able to automatic tracking and supervision, so that the maintenance and overhaul become Quite convenient.

Bridge cranes, making the current work process, mechanization, automation, greatly reducing the labor intensity of workers, and improve productivity, bridge cranes can be considered one of the most widely used rail running cranes, his lifting weight can reach several hundred tons. With the development and improvement of technology, the crane's various functions are more and more powerful, the structure is more and more simple, the performance is more and more reliable, the lifting weight is also more and more large. Bridge cranes are generally divided into three kinds of cranes: ordinary type, simple beam bridge type and metallurgical special cranes. This makes the bridge crane in the steel and chemical industry, port terminals, industrial and mining enterprises and other places are widely used, has become an important equipment indispensable to our production.

Through the above introduction, can make you have a rough understanding of the bridge crane.
