Analysis Of The Types Of Cranes

According to the structure of cranes, cranes are mainly divided into two types: bridge cranes and jib cranes. Bridge-type cranes can operate on rectangular sites and above, and are mostly used for loading and unloading items in workshops, warehouses, open-air yards, etc.

Girder cranes: Girder cranes mainly include single-girder bridge cranes and double-girder bridge cranes. The main girder of the bridge frame of single-girder bridge cranes mostly adopts I-shaped steel or the combined section of steel type and steel plate. Lifting trolleys are often assembled with chain hoists, electric hoists or hoists as lifting mechanism components.

According to the bridge support type and suspension type. The former bridge runs along the crane track on the car beam; the latter runs along the crane track suspended under the factory frame. Single-girder bridge cranes are divided into two types: manual and electric. Manual single-girder bridge cranes have low working speed and small lifting capacity, but their own quality is small, which is convenient for organizing production and low cost. the occasion.

The manual single-girder bridge crane adopts the manual monorail trolley as the running trolley, the manual hoist as the hoisting mechanism, and the bridge frame is composed of the main girder and the end girder. The main beam is generally made of a single I-beam, and the end beam is welded with section steel or press-bent formed steel plate.
