top running crane, single girder or double girder?
What Is Top Running Crane?
Top running crane, as its name implies, is a kind of crane fixed on the top of the roof, which looks like a crane without feet. It is usually running on the track, which is different from truck crane. The crane can be divided into two types - top running single girder crane and top running double girder crane. Top running crane is widely used in various industrial fields, and plays an important role. In some degree, the top running crane promotes the mechanization and automation process. Without top running crane, some project will not be so convenient to achieve.Top Running Crane Advantages
The capacity of top running single girder crane is used in light weight product, 1-15 ton is allowed. It is more economical than a double girder model, because of its lower production cost and lower price. Most common double girder crane capacity are 15-75 ton. Different cranes have their own advantage. The top running single girder crane is more light weight and economical. On the contrary, the top running double girder crane could be used for lifting heavier goods. Heavier capacity lifting is available for custom requirement. The top running double girder crane could provide better headroom for clearance requirement. It is the most important tools and equipment for contribution to achieve the mechanized and automation during the modern manufacturing production and crane transportation.
Characteristics of Different Type of Top Running Crane
Top Running Single Girder Crane Features
Unlike top running double girder crane, the top running single girder crane owns only one girder, so it is smaller and more convenient than double girder crane. The top running single girder crane is widely used for lifting products on various occasions. But it is forbidden in the flammable, explosive, and corrosive media environments. Usually, there are two types of single girder crane - manual model single girder crane and electric model single girder crane.About the main bridge girder of single girder crane, most of the bridge main girder adopts the I-shaped steel or steel plate composite section. The chain block and electric block usually used as crane carriage. The top running double girder crane is combined with three parts - machinery, electric and metal structure.
Top Running Single Girder Crane Application
Compared with the top running double girder crane, the top running single girder crane is lighter, because of its compact dimension, building low headroom ,light weight and small wheal pressures. So it is widely used in warehouse, workshop and stock ground for various production requirements in different fields , such as machinery manufacture plant, metallurgical workshop, electronic, petro chemicals, petroleum, port, railway, civil aviation, electric power station, paper making and building materials and so on. Being different from top running single girder crane. The top running double girder crane is widely used indoor and outdoor industrial mining enterprises, steel and chemical, railway, port and logistics.
