Description

Technical Field

[0001] The invention relates to the technical field of lifting platforms, and in particular to an adjustable aluminum alloy lifting platform and an adjustment method thereof. Background Art

[0002] The lifting platform, also known as a hydraulic lift or lift, is a multifunctional lifting and loading and unloading mechanical equipment. The lifting platform is mainly divided into two categories: fixed and mobile. The working principle of the lifting platform is mainly based on the hydraulic system, which consists of a hydraulic cylinder, a hydraulic pump, a control valve, a pipeline and an oil tank. The hydraulic pump converts mechanical force into hydraulic energy and delivers the hydraulic oil to the hydraulic cylinder. When the hydraulic oil enters the hydraulic cylinder, the piston in the hydraulic cylinder will be subjected to the pressure of the hydraulic oil and generate an upward or downward movement force. By controlling the operation of the hydraulic pump and the flow of the hydraulic oil, the lifting function of the lifting platform can be realized.
