Abstract
The invention relates to a hanging type hill mountainous region orchard operating lift platform which comprises a motive power device, a supporting mechanism, a lifting mechanism, a swing mechanism and a hydraulic control system. The hanging type hill mountainous region orchard operating lift platform controls hydraulic component motion through the hydraulic control system to stably lift a work table to arbitrary working positions of a scheduled working range. The ascending and descending heights of the work table are adjusted through stretching and shrinking of a lifting cylinder. A lifting system is driven by a coupler to complete rotating angles of the work table through a gear rack swing hydraulic cylinder. Adjustment of the work table and the ground inclined angle is achieved through linkage of a leveling cylinder and a follow-up cylinder. The hanging type hill mountainous region orchard operating lift platform can be adapted to special operating environments of hills and mountainous regions.
