Screw-type hand-operated hoist

The screw-type hand-operated hoist is a hydraulic device that drives the screw to open or close the gate through a hand-cranking mechanism, featuring simple operation and a compact structure. ‌
Structural Composition
It mainly consists of a screw, nut, transmission mechanism, frame, and hand-cranking device. The screw and nut work together to convert rotational motion into linear motion, driving the gate to lift or lower. ‌
Working Principle
Rotating the hand-cranking device drives the screw to turn, causing the nut to move linearly along the screw. Through the transmission mechanism, the gate is driven to open or close. It supports manual operation and can also be driven by an electric motor. ‌
Applicable Scenarios
‌Small-scale hydraulic projects‌: Such as irrigation channels and drainage pumping stations, used to regulate water flow and control water levels. ‌
Powerless scenarios‌: Equipped with solar power supply and monitoring modules for remote control. ‌
Technical Parameters
‌Load capacity‌: 0.3-100 tons
‌Travel error‌: Single-turn travel error ≤0.5mm
‌Positioning accuracy‌: Standard equipped with travel limiters, positioning accuracy ±1cm ‌
