したことを特徴とする車輌整備リフター。 The left and right lifters are arranged side by side at a predetermined interval, and each lifter is constructed using an X-shaped parallel telescoping mechanism, and a lifting platform is attached to the upper end. In the lifter, the raising and lowering movement of the lifting platform is performed by the expansion and contraction action of the piston rod of a driving hydraulic cylinder attached to an appropriate location, and an adjusting hydraulic cylinder is provided between the hydraulic oil sending unit and the driving hydraulic cylinder. The adjusting hydraulic cylinder has a partition wall in the middle, and pistons are arranged in the left and right cylinder chambers across the partition wall, and these two pistons are connected by a piston rod, and one side is further partitioned by these pistons. Connect the pipes led out from the hydraulic unit to the cylinder chamber, and connect the pipes extending from the cylinder chamber on the other side partitioned by the piston to the drive hydraulic cylinders attached to the left and right lifters. Characteristic vehicle maintenance lifter.
