technical field

The utility model relates to the technical field of heavy machinery, more specifically, it relates to a beam device for driving.

Background technique

Cranes, cranes, and cranes are common names for cranes, and driving is basically the same as what we call cranes now. The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. It is named for its bridge-like shape because its two ends are located on tall cement columns or metal supports.

At present, the patent document with the notification number CN202785376U discloses an energy-saving and consumption-reducing crane, including two main girders, crane carts and crane trolleys at both ends, the horizontal width of the upper cover plate of the main girder is 950 ± mm, and the web of the main girder The height is 1150±2mm; the two main girder top covers are equipped with tracks, the tracks are in an eccentric position on the main girder top cover, and the distance between the center of the track and the flange on the inner web of the main girder is 110-170mm. This energy-saving and consumption-reducing crane enhances the horizontal rigidity of the whole machine itself, reduces its own weight by 25%, saves steel resources, and thus reduces the power of the motor. Workers observe the position of the crane trolley and judge it based on their work experience. Especially in places with heavy dust and low visibility, it is very dangerous to rely on the human naked eye to assist experience judgment. The main beam has potential safety hazards.
