Lifting machinery is a type of equipment that can move up, down, and horizontally to help lift materials, and is widely used in various factories. Due to the narrow space of the factory building and the fact that the crossbeam and other structures of the factory building can serve as the foot frame of the crane, practical factory cranes are generally bridge cranes, gantry cranes, and electric hoists, which are all very suitable for lifting operations in the factory building.

The bridge crane is a lifting machinery that can be horizontally mounted above the workshop, capable of carrying loads in horizontal, longitudinal, and horizontal directions for material lifting. Bridge cranes are also known as overhead cranes because their two ends are placed on cement columns or metal beams in the factory building, and the entire machine is in mid air.

Install longitudinal rails at both ends of the bridge crane bridge to allow the crane to move longitudinally, making better use of the space below the bridge for lifting heavy objects and avoiding obstacles on the ground. Bridge cranes are currently the most widely used and numerous lifting equipment in the market.

The gantry crane is an improvement on the bridge crane and can be used for loading and unloading goods in material yards and other places outside the factory building. The metal structure of this crane is similar to a door frame in appearance, with two legs at each end of the main beam, which can carry out load movement on the ground track. The two ends of the main beam also have the function of extending cantilever beams. Due to the advantages of high site utilization, large operating radius, and good universality, gantry cranes are widely used in some ports and factories.

This is the simplest lifting equipment that can be used alone or in combination with gantry and bridge cranes. It has the advantages of small size, light weight, and ease of use, and is commonly used in industrial and mining enterprises, factories, material yards, and other places.
