Product Description
JACTON offers 20 ton High lead screw rotating screw jack for Penstocks Sluice Gates, steel screw jacks travelling nut screw jack with Worm Gear Screw Jacks. Knife gate valves, penstocks, dampers and valves for hydraulic works. Traveling Nut screw Jacks are another option. The lifting screw does not move up and down. It only rotates around its axis. The travelling nut moves along the screw. The lifting nut of screw jack is made of bronze to decrease friction. This type of jack is ideal for applications that cannot accommodate a screw protection tube or that require a flush mount.
Our worm gear screw jack is widely used for lifting and lowering sluice gate in modernization hydropower station or hydro-projects, which uses electric motor driven instead of human power starting with a simple manual operation. Motorized Single unit, Double units...Multiple units or tandem worm gear screw jacks arrangements with kinds of motors for gates. Selecting correct worm gear screw jack models following sluice gate sizes, gate weight, gate friction force, water pressure, water impact force, required travel speed etc. 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.
Screw jacks can be connected directly to an electric motor creating a compact linear drive. Standard 3 phase motors are most common. For lower powers DC motors can be used, or servo motors can achieve high performance.
A Inverted Rotating Screw Jack has a lift shaft that moves a nut as it turns. The lift shaft is fixed to the worm gear. This causes the load, which is attached to the travel nut, to move along the lift shaft. A Inverted Rotating Screw jacks has the lift shaft extending out the bottom of the jack.
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.
