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.
