European Double Girder Overhead Crane parts of the overhaul focus

European double beam crane in use before or after a period of time, the need for regular maintenance, the purpose is to eliminate all adverse factors, to avoid failure.The maintenance of European double beam crane is aimed at all aspects, every part can not be ignored.

Let's take a look at the European double beam crane parts maintenance focus!

1. Inspection of crane appearance

On the European double beam crane appearance detection, in addition to a comprehensive cleaning appearance, do not dust, no yellow robe, but also to check whether there are cracks, welding defects.For the European single and double beam crane in the cart, the need to do is to check and tighten the transmission shaft seat, gear box, coupling and shaft, the key is loose;And adjust the brake wheel clearance to make it uniform, sensitive and reliable.
