01
Main Girder
With strong box type and standard camber, there have reinforcement plate inside the main girder. Material of high quality carbon steel Q235B and Q345B.
02
End carriage
Use rectangular tube manufacturing module, butter motor drive, with roller bearings and lubrication.
 
03
Trolley
It is with heavy capacity and high working class. It is developed specifically for lifting that requires accurate and smooth movement.
04
Wheel
Equipped with high quality forged or casting wheel, which will have be heat treated to ensure wheels’ performance.
 
05
Lifting device
The beam body is made of high-quality low-carbon alloy steel, high strength, high temperature resistance;
The hook body is spliced by steel plate, and the rivet is pressed by the forged hammer, stronger and safer than the traditional welding rivet; while the hook body can be free to rotate
06
Operation ways 
Pendant control, remote control and/or cabin control.
 
07
Cabin
The cabin has open model and closed model. It can be installed on left or right side according to the practical situation. And the direction of entering has two ways: sideway entrance and end surface entrance to satisfy the users' choice in different conditions.
