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.

Single-girder cranes usually refer to single-girder bridge cranes. The main girders of electric overhead traveling crane bridges mostly use I-shaped steel or a combined section of steel and steel plates. Lifting trolleys are often assembled with chain hoists, electric hoists or hoists as lifting mechanism components.

Bridge cranes can be divided into single-girder and double-girder bridge cranes according to their categories.

General bridge crane General-purpose bridge cranes are bridge cranes that work in general environments, and their pick-up devices are hooks or grabs or lifting electromagnets (electromagnetic chucks), or two or three of them are used at the same time

Insulated Bridge Cranes Insulated bridge cranes refer to cranes that work in the environment of smelting workshops of non-ferrous metals such as electrolytic aluminum, magnesium, lead, zinc, and copper.
