Description

Technical Field

[0001] This utility model relates to the field of load-bearing tooling equipment technology, and in particular to a manual double-arm scissor lift truck. Background Technology

[0002] A lifting platform is a multi-functional lifting and loading / unloading device. Existing lifting platforms mainly include hydraulic, electric, and manual types. Hydraulic and electric lifting platforms have complex structures, rely on hydraulic systems or power supplies, and are difficult to handle promptly when problems such as oil leaks occur, leading to difficult maintenance and higher costs. Manual lifting platforms typically use a scissor-lift mechanism, achieving extension and retraction through changes in the angle of a linkage mechanism. However, current lifting platforms usually use a single outsole, which can easily become unstable during lifting if subjected to external impacts or if the center of gravity of the loaded equipment shifts. Furthermore, most manual lifting platforms require handwheels at the bottom of the platform, usually requiring the user to climb on and off the platform or other operators to assist in lifting, making operation relatively complicated. In addition, compared to mobile lifting vehicles, fixed lifting platforms are less portable and flexible in use and maintenance. Utility Model Content
