The invention discloses a vehicle transporter servo lifting mechanism. The vehicle transporter servo lifting mechanism comprises a vehicle underframe of a stepped structure, a first stand column and a second stand column are welded to the two transverse sides of the high step position at the front end of the vehicle underframe respectively, a front sliding block supporting base and a second sliding block supporting base are installed on the first stand column and the second stand column respectively in a sliding mode, a front upper layer platform is arranged between the front sliding block supporting base and the second sliding block supporting base, and the two ends of the front upper layer platform are connected with the front sliding block supporting base and the second sliding block supporting base respectively. Loading actions are achieved on the premise of not using an oil cylinder in the front upper layer platform, effective locking, safety, reliability, low manufacturing cost and effective product light weight can be achieved, commercial vehicles can be loaded on the premise of not additionally arranging the oil cylinder or other power mechanisms, a pin shaft and a bracket are used for effective locking, loading is convenient, and product light weight is achieved while cost is reduced.
