Claims

[Scope of utility model registration request]

A fixed support member fixed to the rear or side part of the vehicle body, a rotating shaft rotatably supported by the fixed supporting member, a cylinder that drives the rotating shaft, and a cylinder fixed to both sides of the rotating shaft. A rotating member, a main arm whose one end is pivotally connected to the rotating member and which rotates together with the rotating member in the upward direction, and which together with the main arm forms a parallel link for lifting; a sub-arm which is pivotally attached to the fixed support member side, a vertical link to which the other end of the main arm is pivoted to its upper end and the other end of the sub-arm to its lower end, and the main arm is attached to the upper end of the vertical link. A main platform is pivotally connected to the main platform and maintains a horizontal state by contacting the vertical link, and a sub-platform is foldably connected to the main platform via a hinge. A lifting device characterized by:
