Double-girder Overhead Travelling crane with cabin Control

Of all types of bridge cranes, double-girder cranes are characterized by the greatest variety of design solutions used in their production. Double-girder bridge cranes are used in various industries and are used for work with heavy loads. In modern crane construction, bridge cranes are made of two box-section span beams, fastened with end beams also of box section. The span and end beams are welded from sheet steel by automatic welding. Diaphragms are installed inside to give them rigidity and stability. Such a design allows the crane to operate in heavy modes A3-A7, and also has a small bridge height, which in some rooms can play a significant role. Unlike a single-girder bridge crane, double-girder cranes have a crane trolley equipped with a drive for movement along the main beams. Depending on the needs, the crane trolley can be equipped with a main and auxiliary lift. A stationary hoist or a winch of the deployed type (electric motor, gearbox, brake, drum) is installed on the trolley of double-girder cranes. The Tambov Plant of Load-Lifting Machines manufactures double-girder bridge cranes with standard 4.5; 7.5; 10.5; 16.5; 18 22.5; 24; 28.5; 32 meters or any other length depending on the specific distance between the rails of the crane track. The lifting height of the load as a whole depends only on the height of the room and, accordingly, the height of the installation of the crane tracks inside the room in which the bridge crane is installed.
