Aircraft PRM Medical Lift auxiliary beams always become frame structures. It is composed of an auxiliary beam frame, a front support frame and four telescopic hydraulic supports. The lifting frame is composed of two high-strength rigid components hinged together to form a scissor-type fork frame structure. Its upper and lower parts are respectively hinged to the carriage and the auxiliary beam. Through the extension and retraction of the hydraulic cylinder, the lifting frame can be raised and lowered. There are two independently operable working platforms at the front and back to facilitate passengers with mobility issues to board and disembark the plane. The front platform can be extended and retracted forward and backward, making it convenient to approach the boarding door. The rear platform can be folded, retracted and raised vertically, making it convenient for passengers with mobility issues to get on and off the vehicle. The front platform is equipped with a guardrail, and the guardrail of the telescopic platform can also be retracted. Anti-collision protection measures are installed on the outside. The Aircraft PRM Medical Lift is modified based on the Qingling Type II vehicle chassis (Qingling 700P) truck.
There is a set of working status indicator lights in the cab to show the working condition. The cab is equipped with a set of operation panels for the retraction and extension of the support feet and the lifting and lowering of the body. The interior of the body is equipped with a set of operation panels for lifting the body, extending the platform and moving it left and right.
On the left side of the body, there is a side door for the convenience of staff and accompanying personnel to get on and off the body, and safety handrails for going up and down the steps are also installed.
Four hydraulic H-shaped upright support feet are installed around the entire vehicle.
The control system combines manual oil circuit control with electrical circuit control.
