Description

Technical Field

[0001] The utility model relates to the field of lifting platforms, and more specifically, to a portable hydraulic lifting platform. Background Art

[0002] In the process of industrial production or construction projects, it is often involved to lift people or materials and goods to a certain height. Therefore, a hydraulic lifting platform is used to lift people or goods to a certain height. The hydraulic lifting platform greatly facilitates industrial production and construction work. The existing hydraulic lifting platform generally supports people and places goods through the platform plate. The platform plate area of ​​the existing lifting platform is fixed and the area of ​​the platform plate cannot be changed. Therefore, during use, when a large amount of goods needs to be lifted, the stepping space of the people will be occupied, thereby affecting the adaptability of the entire lifting platform and making it inconvenient to use the lifting platform. At the same time, the existing hydraulic lifting platform lacks a protective structure. When the hydraulic lifting platform rises to a certain height, when the lifting system of the lifting platform fails, the platform plate cannot be lowered and people cannot get off the lifting platform, which causes a safety hazard and makes it inconvenient for the entire lifting platform to protect the users.
