A ladder is a device that is installed at the rear of a flatbed trailer to enable the vehicle or equipment to be transported up to the transport platform or down to the 

ground. The application of the hydraulic ladder realizes the automation of the ladder retracting and solves the trouble caused by the driver to close the ladder.

The ladder can be divided into two types: non-foldable and foldable, and has various combinations (width adjustable, manual hydraulic assisted operation, 

hydraulic support, etc.), which is a new hydraulic product. At present, it has been applied in the fields of construction machinery transportation and armored vehicle 

transportation.
