Description

A multifunctional gantry crane

technical field

The utility model belongs to the field of crane engineering machinery, in particular to a multifunctional gantry crane.

Background technique

The gantry crane is a variant of the bridge crane. In the port, it is mainly used for loading and unloading operations of outdoor cargo yards, stockyard cargo, and bulk cargo. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can directly walk on the track on the ground. The two ends of the main beam can have outrigger cantilever beams. The gantry crane has the characteristics of high site utilization rate, large operation range, wide adaptability, and strong versatility. It is widely used in port freight yards. The most widely used is the rail-type gantry crane. This kind of crane is mostly used. Type and truss structure, the most widely used. It can carry various pieces and bulk materials, with a lifting capacity of less than 100 tons and a span of 4 to 39 meters. Ordinary gantry cranes with grabs have a higher level of work. Ordinary gantry cranes mainly refer to hook, grab, electromagnetic, hoist gantry cranes, and also include semi-gantry cranes. But now the rail-mounted gantry crane has a single form of conveying movement, and its functionality and practicability are not strong, which hinders the development of construction machinery to a certain extent. Therefore, a multi-functional gantry crane is urgently needed to eliminate these disadvantages.
