PURPOSE: A hydraulic tuning apparatus of a lift for vehicles is provided to enable a precise tuning operation by removing accumulated pressure. CONSTITUTION: A hydraulic tuning apparatus of a lift for vehicles comprises a first main cylinder(10), a second main cylinder(20), a first auxiliary cylinder(30), a second auxiliary cylinder(40), a main supply line(H0), a first tuning line(H1), a second tuning line(H2), a first auxiliary line(H3), a second auxiliary line(H4), a first valve(V1), and a second valve(V2). The first main cylinder is provided on a side of a lift, and the second main cylinder is provided on the other side of the lift. The first auxiliary cylinder is serially connected through the first tuning line to an outlet port(10a) of the first main cylinder. The second auxiliary cylinder is serially connected through the second tuning line to an outlet port(20a) of the second main cylinder. The main supply line connects the first main cylinder and the second main cylinder to the hydraulic pump. The first tuning line connects the outlet port of the first main cylinder to an inlet port(30a) of the first auxiliary cylinder. The second tuning line connects the outlet port of the second main cylinder to an inlet port(40a) of the second auxiliary cylinder. |
