The invention provides a lifting device and an operation vehicle. The lifting device comprises a fixed frame, a first sliding frame, a second sliding frame, a telescopic driving part and a lifting assembly. The first sliding frame is arranged at any end of the fixed frame and is in sliding connection with the fixed frame. The second sliding frame is arranged at the other end, relative to any end,of the fixed frame and is in sliding connection with the fixed frame. The telescopic driving part is used for driving the first sliding frame and the second sliding frame to slide along the fixed frame so that at least part of the first sliding frame and at least part of the second sliding frame can stretch or contract relative to the fixed frame. According to the lifting device and the operationvehicle, the first sliding frame and the second sliding frame are arranged, the operation range of the lifting device is enlarged, the occupied space is reduced, and the flexibility of the lifting device is improved.
本发明提供了一种升降装置和作业车。升降装置包括固定框架、第一滑动框架、第二滑动框架、伸缩驱动部件和升降组件。第一滑动框架设于固定框架的任一端,并与固定框架滑动连接。第二滑动框架设于固定框架相对于任一端的另一端,并与固定框架滑动连接。伸缩驱动部件用于驱动第一滑动框架和第二滑动框架分别沿固定框架滑动,以使第一滑动框架的至少部分和第二滑动框架的至少部分相对于固定框架伸展或收缩。本发明通过设置第一滑动框架和第二滑动框架,增大了升降装置的作业范围,并且缩小了占用空间,提高升降装置的灵活性。
