Nejběžnější jeřáb používaný v dílně - elektrický mostový jeřáb je nejběžnějším typem jeřábu používaným v dílně. Jsou to lehké a malé jeřáby, vybavené kladkostroji CD a MD. Rozsah nosnosti je obecně mezi 1-16t a rozpětí je mezi 6-25 metry. Pro větší nosnost a rozpětí je nejlepší zvolit elektrický dvounosníkový jeřáb. Prostředí použití je řízeno v rozsahu -30-+40℃.

The trolley operating mechanism of the overhead traveling bridge crane is the transport mechanism of the entire crane, including the motor, controller, coupling, transmission shaft, reducer, angular bearing box and trolley wheels, etc.

1. During lifting operations, it is necessary to have a comprehensive understanding of the working environment, travel routes, buildings, and object weights at the work site. 2. Operators should sound the signal before carrying out lifting, turning, luffing, walking, hook lifting and other actions, and strictly implement the commander's signal. Special operators must have a special operation safety operation certificate.

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.
