Motorized Screw Jack Hoisting Sluice Gates

Motorized screw jack hoisting sluice gates, knife gate valves, penstocks, slide gates, dampers and valves. A penstock is used for controlling the flow or level of a liquid and consists of a sliding door controlled by a mechanically operated spindle that moves over an aperture in a frame which in turn is secured onto a structure. Penstocks have several applications in arresting and controlling the liquid flow. They are used on Waterways, Power plants, Industrial effluent plants, Drainage and Flood control as well as being used in large numbers on water, wastewater and sewage treatment plants. Penstocks, unlike valves, are normally fitted into or onto the civil structure framework either in channels or over an aperture in a wall. The channels and apertures are sized to accept a range of flow situations and the penstocks are required to suit. This requirement alone dictates that they are a bespoke product.

Screw jacks are suited for lifting, lowering, pushing, pulling and pressing. They can be operated manually or by electric, hydraulic or pneumatic motor. Stainless Steel Machine Screw Jacks are ideal for use in demanding environments where corrosion resistance is required. All external components are manufactured from 300 series Stainless Steel materials. These jacks use a stainless steel worm with a high strength bronze drive sleeve. 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.

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.

Screw jack gearbox lift hoist for irrigation sluice gates in Rivers, Canals, Power Station Projects, which uses electric motor driven instead of human power starting with a simple manual operation screw jack. Motorized Single unit, pair units...multiple units or tandem screw jack gearboxes arrangements with kinds of motors for gates. Selecting correct screw jack gearbox models following sluice gate sizes, gate weight, gate friction force, water pressure, water impact force, required travel speed etc. The common points include inverted type screw jack gearbox, translating screw design, clevis end, protective tube etc.

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.
