Crane in operation, to withstand a variety of loads (such as static load, dynamic load, alternating load, shock load, vibration load, etc.), the bearing parts and structural components will produce the corresponding stress and deformation, if more than a certain limit, will lose function or even destruction, thus causing danger. 1、Introduction of cranes load Crane in the course of operations, the complexity of the load bearing is not only reflected in the diversity of load types, and with the different working conditions of the crane operation and the performance of variable characteristics. Load is the crane and its component parts of the normal working force analysis of the original basis, but also parts of the scrapping or the cause of the accident to determine the basis of analysis, load to determine the accuracy of the results of the calculations will have a direct impact on the safety of the conclusions…

The cranes rust causes and painting corrosion prevention, outdoor gantry crane rust, gantry crane rust, chemical workshop crane rust corrosion, crane corrosion, crane anti-corrosion, painting, spray paint did not deal with the situation is the crane rust Z easy to happen. Here we detail crane rust rust are those reasons and how to prevent crane corrosion rust. Outdoor gantry crane rust corrosion, gantry crane rust is due to long-term exposure of cranes in the air, protective measures are not complete, or chemical industry workshop cranes, due to prolonged exposure of cranes to the surrounding corrosive gases or corrosive liquids for chemical reactions and the process of loss. Especially when the air is contaminated with various chemical aggressive media, corrosion will be more serious, even if the crane has been painted to protect the crane, due to the use of the wind, sun, hot and cold changes in the climate, rain…
