  • Lifting/Lowering Underframe and Load-bearing Device Having Same
    Publication number: 20230346619
    Abstract: A lifting/lowering underframe and a load-bearing device having same. The lifting/lowering underframe comprises a lifting/lowering mechanism (2) which comprises a first lifting/lowering frame (21), a second lifting/lowering frame (22) and a driving member (23). The two ends of the driving member (23) are connected to the first lifting/lowering frame (21) and the second lifting/lowering frame (22) respectively; the driving member (23) is an electric push rod, and the driving member (23) kept between the first lifting/lowering frame (21) and the second lifting/lowering frame (22) can electrically drive the first lifting/lowering frame (21) and the second lifting/lowering frame (22) to move relative to each other. The lifting/lowering mechanism (2) is easy to maintain, has low noise and can work normally in high/low temperature and anticorrosion/explosion-proof harsh environments.
