Overhead crane is the most frequently used lifting equipment for general material handling. According to different lifting requirements, overhead crane can be classified into different types with different features.
Types of Overhead cranes based on application features
Overhead crane with hook
For general use, it refers to the overhead crane applied in normal environment, with normal temperature, normal humidity, with no dangerous gas, or mediums, etc. Overhead crane for general use is the most widely used lifting equipment, with the lifting capacity ranging from 1 ton to 800 ton +, which is widely used in workshops, factories, warehouses, workstations, etc.
Overhead crane with hook, Double trolley overhead crane
Double-trolley overhead crane
The double trolley overhead crane is a type of crane equipped with two trolleys, which can lift loads simultaneously or separately. The double trolleys overhead crane is used widely used to lift long loads or loads with two long distance lifting points. With the lifting capacity of 5 to 400 tons, the double trolley overhead crane is used widely to handle heavy loads, in places such as storage, workshop, stock yard, or other factories and mines, etc.
Insulation overhead crane
Insulation overhead crane is also called isolation overhead crane which is a special designed overhead crane with insulation, used in charged environment, such as, electricity power plants, and factories, where has electrolyse non-ferrous metals, such as, aluminum and magnesium, etc.
Insulation overhead crane, Explositon-proof overhead crane
Explosion proof overhead crane
Explosion proof overhead crane is an overhead crane installed with anti-explosion electric hoist, and anti-explosion devices over all motors and electrical devices. Explosion proof bridge crane is applied to sites, where is not higher than the II B or II C-class, and the sites with explosive air mixture formed with inflammable gas (or steam) and air whose factory ignition.
Metallurgic overhead crane
Metallurgic overhead crane is a type of overhead crane used in the metallurgical plants, with many different sub-types according to the functions of the overhead cranes, taking ladle overhead crane for example. Ladle overhead crane is used specially for transporting and handling hot metal in the process of smelting liquid metal, etc.
