Side-crank Screw Lifting Machine Factory

The side-crank screw hoist is a manually operated flat gate hoisting device, driven by human-powered cranking. It features anti-theft water functionality and a self-locking mechanism, making it suitable for small to medium-sized hydraulic engineering projects.
Structural Features
Composed of a housing, support frame, screw rod, hand crank, and other components, it achieves gate opening and closing through manual cranking. Its core component is the threaded rod structure, which converts rotational motion into linear motion to drive the gate's lifting and lowering.
Applicable Scenarios
Primarily used in areas without power supply, such as water conservancy and hydropower, municipal construction, and agricultural water conservancy. It meets gate control requirements in special environments like plains and mountainous regions.
Installation Requirements
During installation, the foundation plane must be level at 180°, with the screw axis perpendicular to the horizontal plane of the gate platform beam. The deviation of the longitudinal and transverse centerlines should not exceed ±3mm.
Performance Parameters
Capacity Range: 0.3T–100T (varies significantly by model)
Operation Method: Manual side-crank type (human-powered operation)
Anti-Theft Design: Equipped with an anti-theft nozzle and specialized tools to prevent water leakage
