Electric motorized driven screw jack are used for rivers, canals, power station sluice gate lifting projects in Australia and Vietnam, which uses electric motor driven instead of human power starting with a simple manual operation screw jacks.

Different Types of Screw Jack For Motorized Jacks1. Worm gear maching screw jack with load 1/4 ton - 100 tons, customized larger capacity 250 tons.2. Worm gear ball screw jack with load 1 ton - 35 tons.3. Bevel gear screw jack with load 2.5 ton - 50 tons.Different Versions of Screw Jack For Motorized Jacks
1. Translating Screw Version: The rotation of the worm gear acts directly on the lift screw and the lift screw translates linearly. Unless the end of the lift screw is fixed (dependent on customer requirements), the lift screw will tend to rotate due to friction between the screw threads.2. Anti-rotation with Keyed Screw Version: As above but the lift screw is keyed such that it cannot rotate. This is important if the lift screw end is not to be fixed to the load. Both the keyed and un-keyed translating screws are commonly used in applications where more than one screw jack is attached to a common load.3. Rotating Screw Version: The lift screw is fixed to the worm gear so rotation of the worm gear causes rotation of the lift screw thus translating the nut along the lift screw when the nut is attached to the load.Advantages of Screw Jack For Motorized Jacks1. Simple and inexpensive solution in comparison with hydraulic and pneumatic systems.2. A defined load can be moved to an exact position at a preset speed.3. Several Screw jacks can be synchronised lifting systems by means of connection shafts and an electronic controller, for example in stage construction.3. Can be positioned very precisely.4. They can exert the same forces in both the pushing and pulling direction.5. An economically very interesting solution compared to pneumatic and hydraulic systems.6. Many technically ideal and economically interesting solutions can be realised with our modular construction kit concept.7. Screw jacks are valued by design engineers as standard machine elements.Applications of Screw Jack For Motorized JacksScrew Jack is the ideal product to push, pull, lift, lower and position object loads. They are essential components in automated machinery because of high reliability and synchronization. Additionally, screw jack is increasingly finding uses as alternatives to conventionally pneumatic and hydraulic systems.1. Platform lifting applications2. Opening and closing of penstocks3.
