Structural characteristics and usage environment of gantry crane

The yard gantry crane manufacturers has a simple structure and is easy to operate, and its bridge is firmly supported on the ground by brackets on both sides. It is like a dragon entrenched on the clouds, so the gantry crane is also called a gantry crane. The working places of gantry cranes are usually open-air environments such as seaside docks, railways or other large heavy industry factories. The temperature changes in the open-air environment are relatively drastic. For example, in some sites with relatively harsh environments, dust and harmful gases are significantly worse, and in During the work process, negative factors such as vibration and impact are detrimental to it. What is more serious is that when the capacity of the power supply transformer becomes smaller and the cross-section of the power supply cable shrinks, it often causes an instantaneous voltage shortage. .

Generally speaking, general-purpose industrial yard gantry crane price are relatively common and highly practical. They consist of a gantry, a trolley operating mechanism, a lifting trolley and electrical parts. The custom yard gantry crane company has only one side supported on the ground. The structure of the gantry includes the upper bridge, outriggers, lower beams and other parts. Nowadays, the operating range of cranes has been expanded to a large range. The main beam can be modified into a cantilever, or a lifting trolley can be used to promote and apply the gantry crane’s operating range to a certain extent.

According to different structural characteristics, yard gantry crane suppliers can be divided into hook gantry cranes, grab gantry cranes, electromagnetic gantry cranes, and dual- or three-purpose gantry cranes. Among them, the hook gantry crane is suitable for larger places, such as stations, docks, large enterprise factories, freight yards and warehouses; the grab gantry crane is suitable for some scattered and large-scale transportation; dual-purpose or Three-purpose gantry crane is used in places where materials change frequently.
