The cost of transportation, installation, commissioning and maintenance of bridge cranes will usually account for a part of the total cost, but the specific proportion will be affected by many factors, including the type of crane, size, design requirements, installation location and operating environment, etc.

In a specific project, the following factors may affect the proportion of overhead crane transportation, installation, commissioning and maintenance costs:

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.
