1. Advanced Technology, High Quality, Good Price 2.easy to load or unload cargo 3.van box  The wing opening system adopt the unique oscillating cylinder designing, the wing door can open 270°degree, have a small rotative semidiameter, The door cling to the top truck by the type of fold when the doors are opening. Have a low request for the space of the enviroment, and it easily to across the narrow road, which have a high applicability. High safty, so you don't worry about drop suddenly of the door. The structure is compact and portable, so the assembling space is small. This wing opening system fit to use the high class box truck and securicar which have high request of the security. The wing opening system according to car battery as the power, and the system is independent, Sumply assemble, so there is no influence when the truck have the demages. The system use the balanced valve, which make the wing opening door is more steady when the door is decending. What’s more, the Wing opening door can lock up any position, so it is safer and more reliable. synchronizing mechanism is connected by mechanical axis, So it is more reliable than the synchronizing hydraulic. The equipment adopts import power unit, so the performance is more stabilize and reliable. We add the oil clinder locking structure, which avoid the wing door to opening unexpected. So the transportation is safer. The electrical system adopts fixed controlling panel, the locking action and opening/closing action can be controled seperately. The buttons are locked by each other, which avoid the to operate in error.
