Abstract

A loading test test-and-control system and method of vehicle lifter lifting unit, the system is used to test a lifting unit, comprising a base, the base is provided thereon with a support bracket capable of installing the lifting unit to be tested; the support bracket is provided with a loading unit for applying a loading force to the lifting unit to be tested; the loading unit is electrically connected with a control unit which can control the pressure applied by the loading unit according to a set value. The method uses the system. Before the assembly of the vehicle lifter is completed, the system may carry out a loading test for the lifting unit and verify the function and static strength of the lifting unit, facilitating the test and saving cost.
