How does Dongqi turn electric crane system to automatic?
In recent years, with the wide use of computer, Dongqi has paid more attention to the computer. In the beginning, Dongqi starts to apply computer to assist design system, and later uses computer to make modular design of overhead crane. Under the strict scientific theoretical guidance, the computer can accomplish the overhead crane design about structure, mechanism, components with multi-level of standardization and modular units.

The progress of electric bridge cranes refers to a few modules those need modified. When design new crane, just choose different modular units and make new combination, which can improve the level of versatility and change the products of single small batch into module production of relative batch. In this way, a few modular units can also combine into cranes of various function and configuration to meet market need and increase competition. Therefore crane manufacturers can save much crane cost.

The progress of lifting speed and brake in accurate positioning is made through crane hook with low running speed. The brake system of electric overhead crane also applies microprocessor to control and monitor. Control system used in overhead crane can not only save human, enhance working efficiency, but also improve the working condition of operator. The anti-collision device of distance detection adopts radio signal type. Usually the overhead crane sends a warning signal first, then the crane system decreases the speed to 50%, finally the motor power is cut to control the crane.
Why does Dongqi rank top in the cranes industry?
Due to the application of new material and technology in steel industry, the steel quality has improved. When design the rigidity of main girder, higher allowable stress can be used, not needs very high safety factor in order to reduce the amount of crane material (it doesn’t means dangerous) and decreases the weight and price of crane system. Once the cranes’ weight reduce, it can adopt driving device with lower power to start so that reducing power and saving cost. Most processing equipment adopt high accurate and effective processing center and automatic machine with digital control. Dongqi uses new technology to improve quality & efficiency, save labor & cost.
