motorized screw jack hoisting sluice gates, worm gear screw jack gearboxes for raising and lowering canal gates.

Small area water regulation makes a valuable contribution to the prevention of damage, whether it is caused by excess water or a lack of water. Sluice gate jacks are the ideal solution for this. They are used on streams and rivers, in sluices and power stations to regulate the water level and turbine capacity and to drain and flush reservoirs. In open water near towns, sluice gate jacks are used in emergency water extraction equipment for fire fighting. The range of systems available today is wide and varied to meet specific application requirements.

Many modernization programs for the operation of canals that deliver water to the agricultural community involve the mechanization of canal gates. Sluice Gate Jacks provide a method of raising and lowering canal gates using electric motors / geared motors / worm gear reducers instead of human power starting with a simple manual sluice gate jack or motorized screw jack hoisting sluice gates, worm gear screw jack gearboxes for raising and lowering canal gates

Common to most of motorized screw jack hoisting sluice gates are the following elements:
1.Single unit motorized screw jack attached directly to the sluice gates or one electric motors / geared motors / worm gear reducers driven multiple units or tandem double input shaft screw jacks attached directly to the sluice gate.
2.Worm and worm gear set, worm gear and lifting screw set that rotates to raise and lower the sluice gate.
3.Gear reduction mechanisms used to control the lifting speed of the sluice gate and to provide a mechanical advantage to overcome the forces involved in lifting the sluice gate.
4.Limit switches to stop the electric motors / geared motors / worm gear reducers once the sluice gate has reached the upper or lower limit of travel.
5.Inverted translating screw jack with clevis end which is attached directly to the sluice gate. Because of sluice gate both side guiding supports, the lifting screw travels up and down with sluice gates.
6.Screw jack with acme screw, which has self-locking, precision positioning features, no need any brake mechanisms or other locking systems.
Russia Water Barrier Projects
Customers technical details: According to the account of our engineers the weight of water barrier is to be 1 ton with the pressure. The width of our water barrier is 1500 mm, the length-3000 mm, The parameter of our motor is 7,5 kw with ,1450 rpm, and the reductor with 28 rpm, So we need a screw with a length-3000 mm and with the diameter -55-60 mm /12 pieaces.
Solutions:
1 Ton Weight Water Barrier With The Pressure Is Hoisted By Double 20 Ton Worm Gear Screw Jacks 3000 MM Screw Length In Russia. Using 20 ton worm gear screw jack with lifting screw diameter 64mm, pitch 8mm, screw travel length 3000 mm. Following customers motor and the reductor, final output 28 rpm. 20T jack use high speed ratio with 1 mm travels per revolution of input shaft.
