Inclined Screw Hoist Factory

The screw-type inclined hoist is the abbreviated term for the inclined screw hoist, primarily used for the opening and closing control of flat gates, featuring the following characteristics:
Structure and Working Principle
It employs a threaded rod transmission system, driven manually or electrically via bevel gears or worm wheels to achieve the lifting and lowering of the screw rod, which is directly or indirectly connected to the gate leaf. Its structure is compact, installation is straightforward, making it particularly suitable for small and medium-sized hydraulic engineering projects. ‌
Functional Features
‌Forced Gate Closing and Self-Locking Function‌: The screw rod serves as both the transmission component and the load-bearing component. Mechanical self-locking is achieved through thread friction, ensuring the gate remains reliably in place at any position, unaffected by water pressure. ‌
Anti-Theft Design‌: Equipped with anti-theft devices and specialized tools to prevent non-professional operation. ‌
Ease of Operation‌: Supports manual hand-cranking or electric drive, with hand-cranking pressure less than 15 kgf and rapid directional speed change. ‌
Applicable Scenarios
Mainly used for controlling flat gates in projects such as reservoirs, irrigation districts, rivers, and hydroelectric power stations, compatible with small and medium-tonnage gates like 3T and 5T. ‌
Maintenance Requirements
Regular lubrication of the screw rod and replacement of worn components (such as load-bearing nuts) are necessary, with low daily maintenance costs.
