Product Description

JACTON offers Manual worm gear screw jack for lifting of canal gate, Electrical Sluice Gate Screw Hoist Systems, positioning water flow gates linear actuator. Knife Gate Valves, Penstocks, Dampers, Check valves, Slurry Valves Valves for Mining Service, Paper Industry, Dams and Hydrological Projects.

Many programs for the operation of canals that deliver water to the agricultural community involve the mechanization of canal gates. Gate jacks provide a method of raising and lowering canal gates using electric motors driven instead of human power operated. motorized screw jack for sluice gate, is popular on the world water power projects. These worm gear screw jacks usually have top plate or clevis end. And they can be driven by gear motor or hand wheel. The common models are 1t, 2.5t, 5t, 10t, 15t, 20t, 25t, 35t and 50t. The screw length 0.6m, 1m, 1.5m, 2m, 2.5m, 3m, 3.5m, 4m, 4.5m, 5m, 5.5m and 6m. We can make the jack screw length following your needs.

How Screw Jacks Work?
Main components of screw jacks are trapezoidal lifting screw, worm screw, worm gear and gear housing. Worm screw is rotated manually or by motor. Worm gear is rotated by worm screw. The lifting screw moves through the rotating worm gear. The linear motion speed of lifting screw depends on thread size and rotation ratio of worm gears.

Sluice Gate Screw Jacks Features:
1. Inverted type, screw translating type, clevis end or top plate, with a protective tube.
2. Standard lift screw is a self locking ACME screw with C45 steel material. Optional stainless steel screw. 
3. Worm gear screw jacks can be used as either single drive units or multi lifting systems as per the weight and sizes of the gate.
4. Screw jacks can be manually operated, or motorized.

A Screw Jack also known as a Worm Screw Jack, is a device used to convert rotational motion into a "push-pull" linear motion. It utilises the property of a screw thread providing a mechanical advantage which means that it can be used to amplify force. The rotary movement can be supplied manually or thanks to the help of hydraulic or pneumatic motors. Or thanks to electric motors, like the induction motor!
The entirely newly developed series of stainless worm gear screw jacks has been designed specifically for the tough requirements of e.g. modern paper machines. This new series is based on a standardized construction kit, which may be combined individually. Due to high-grade stainless steel and innovative technology there should not be any obstacle anymore to a mechanical lifting solution in the field of steel hydraulics construction, food industry as well the explosion-proof area.
Optional screw end adapters are available for screw jacks. Choose a top plate or clevis end to meet your application requirements. Top Plate Screw End Adapters offer a perpendicular mounting surface to easily connect to your structure. Standard mounting holes assure a secure bolted connection. Clevis Screw End Adapter allows for a pinned, pivoting application.
