Technical Field

[0001] This utility model belongs to the technical field of scissor lifts, specifically relating to a portable scissor lift. Background Technology

[0002] A scissor lift is a type of lifting machinery consisting of interlocking support rods that rises or falls under the action of hydraulic equipment, thus changing the height of people or objects. It also refers to equipment used for lifting and conveying in logistics systems such as factories and automated warehouses.

[0003] Currently, the power units of scissor lifts require the selection of 220V or 380V motors to meet the requirements of different areas. This inconsistency in configuration increases the error rate in selection. Moreover, this type of lift must be used in places with power supply and cannot be used outdoors without power supply, so its application is limited.
