The main beam is made of U steel rolled by steel plate, and welded with flange beams to form a box design. The end beams are made by the same technique and material as the main beam. In case of heavier load or larger span, the end beams and main beam will be made of welding U shape groove. The main and end beams are connected by intensive bolts for convenient transportation and assembling.

Travel Unit
This crane is driven in two separate ways. The cone shape braking motor or solid rotary motor (with magnetic brake) is the driving part. While the transmission part is “ open-close” gear, and the close gears are LDA or LDH gear box.
Electric Devices
The motors are cone-shape cages ZDY, or YSE solid rotary ones. These two types have different electric control system. The hoist and the crane are protected by safety devices, such as lifting limit switch, terminal limit switch, over load limit, wrong phase and over current protection etc.
