A hand-operated winch hoist is a gate control device that combines manual operation with mechanical transmission, primarily used in fields such as water conservancy, hydropower, and municipal construction.
A hand-operated winch hoist is a mechanical device that controls the opening and closing of gates through manual operation, integrating the features of hand-operated hoists and winch-type hoists. It is mainly used for gate control in water conservancy, municipal projects, and environments without electricity. ?
Below are its core features and applications:
Core Structure
It adopts a design that combines a manually driven screw rod with a mechanical transmission system, including components such as a support frame, gear set, pressure bearing, nut, screw rod, and hand crank. By manually turning the handle to rotate the screw rod, a worm gear mechanism is used to achieve directional speed change and flexible operation, enabling the gate to be raised or lowered. ?
Functional Features
?Manual Operation?: Does not require electrical power, making it suitable for environments without electricity supply. ?
Self-Locking Function?: The gate can be locked at any position, ensuring operational safety. ?
Anti-Theft Design?: Equipped with an anti-theft lock device to prevent unauthorized operation. ?
Multi-Type Compatibility?: Supports customization for specifications ranging from 3 tons to 60 tons, adaptable to gates of different sizes.
Lightweight and Flexible?: Easy to crank, fast directional speed change, and simple maintenance.?
Installation Requirements
The foundation plane must be kept level (deviation ≤ 3mm), the screw rod axis must be perpendicular to the horizontal plane of the gate platform beam, and aligned with the centerline of the gate (deviation ≤ 3mm). ?
Applicable Scenarios
Commonly used in areas without electricity supply, such as mountainous regions and plains, often paired with cast iron gates. Suitable for water conservancy and hydropower projects, agricultural water facilities, and similar scenarios. ?
Widely used in water conservancy and hydropower projects, municipal construction, agricultural water conservancy, and water supply and drainage systems without electricity supply, supporting gate operation for loads ranging from 3 tons to 100 tons.
