Therefore, since the force exerted by the hydraulic cylinder is configured to act mostly in the upward direction of the pantograph link, there is an effect that it can be raised with a smaller driving force at the time of initial rise. The motor capacity of the drive motor for driving the motor can be made smaller than that of the conventional motor, so that the cost required for the construction can be reduced, and the breakage of the clevis pin or link pin connecting the hydraulic cylinder and the pantograph link can be prevented At the same time, it can be installed without making a buried base on the ground.

However, such a lifting device is shaken because the pantograph link is not balanced during ascending and descending, which raises the risk of a safety accident.

In addition, the Korean Intellectual Property Office (KIPO) Publication No. 10-2008-0061221 discloses a "vehicle-fixed-cost lift ", and includes a lower elevating mechanism for elevating and lowering a platform provided at an upper portion of a pit provided concave on the floor surface, Wherein the elevating means comprises an elevating means provided at the elevating and lowering mechanism of the elevating and lowering means for elevating and lowering a vehicle supporter provided at an upper end thereof and which is capable of closing the pit opening surface with the vehicle supporter by a descending operation of the elevating means, A cover portion that covers the upper surface of the platform except for the operating portion of the elevating mechanism is provided on the platform for the fixed-rate lift, and when the elevating means is moved up, And the cover portion closes the pit opening surface.

Therefore, the lower end portion of the elevating mechanism is not exposed by the cover portion, and the opening surface of the pit can be made as flat as possible even at the upper limit position of the vehicle pedestal, so that the worker is hardly disturbed and workability is improved.

However, such a vehicle-lifting lift also has a problem in that the risk of a safety accident becomes high because the X link is not balanced and the vehicle is shaken.
