Aircraft lifting system with hydraulic locking mechanism

Abstract

The invention relates to a system of lifting and lowering aircraft equipment with a hydraulic lifting mechanism including: a lifting and lowering mechanism (10) with a first pair of rotating joints (11) to allow the lifting and lowering mechanism to rotate on the transport vehicle; a hydraulic cylinder (20) to lift and lower the lifting and lowering mechanism (10) rotating around the first pair of rotating joints (11); a movable mounting plate (30) that slides along the length of the lifting and lowering mechanism (10) through a guide rail mechanism (31); a screw cylinder (40) to drive the movable mounting plate (30) to slide up / down on the lifting and lowering mechanism (10); Hydraulic locking mechanism (60) to lock the lifting frame (10) when the lifting frame is in the retracted state.
