Underhung overhead crane with complete runways are mainly used for the transportation of materials in indoor machinery manufacturing and processing workshops, assembly workshops, warehouses, material yards, for lifting fixed maintenance equipment such as power plants, and other occasions. They can also be used in metallurgy and casting workshops as auxiliary lifting equipment. Besides, it is not suitable for flammable, explosive, combustible gas, dust and corrosive gas environments. However, it is not suitable for nuclear radiation environment and toxic gas environment.

Overhead crane lifting equipment come in two common styles: single girder and double girder cranes. Single girder bridge cranes feature simplicity, lightweight construction, and cost-effectiveness, making them suitable for small and medium-sized lifting operations.

In industry and construction, lifting equipment plays an important role, including cranes and gantry cranes. Although both are mechanical devices used to carry and lift heavy loads, there are some distinct differences in design and purpose between cranes and gantry cranes.

Single girder crane is a common lifting equipment widely used in industry and construction. When choosing lifting equipment, it is crucial to know its maximum load capacity.
