Two-set linkage screw jack system can be "L", I and T configuration.  It usually consists bevel gearbox, screw jack, electric motor, gear reducer, hand wheel, pillow block bearing, jaw coupling, line shafting.

Four-set linkage screw jack system can be  I and T configuration, transmission efficiency can be 85% .

Worm gear screw jacks not only can be used by single unit, but also can be used by multiple units. Multiple screw jacks can make up to a screw jack system together with spiral bevel gearbox,connecting shafts, couplings and motor etc.

The Worm Gear Screw Jack are ideal solutions for applications where electricity or power generators is inconvenient or dangerous, light weight, low duty cycle, low target cost and short travel length. 

Screw Jack for Sluice Gate Worm gear screw jacks are used for rivers, canals, power station sluice gate lifting projects. The jack screw used is trapezoidal screw, because it has self-lock function. And trapezoidal screw jack is suitable for heavy load and slow speed. It can be manual or electric driven according to detailed need.

when hydraulic, pneumatic or chain systems are prohibitive choices. These jacking system arrangements or configurations can be built in many formats with the use of bevel gearboxes, motors, reduction gearboxes, drive shafts, couplings, plummer blocks and motion control devices. Four of the most popular system configurations are the ‘H’, ‘U’, ‘T’ and ‘I’ configured jacking systems. Note that multiple screw jacks can be linked together mechanically or electrically. The latter is useful if there is no space for linking drive shafts. A screw jack system is where more than one screw jack is operated in unison to achieve a linear movement. The screw jack system arrangement is also commonly referred to as a “screw jacking system”.

Traveling Nut Design ( Rotating ) This design incorporates a lifting screw keyed to the worm gear as a single unit, forcing the lifting screw to rotate in the gearbox, but not translate. A traveling nut, running onthe rotating screw generates linear motion for the attached load. This type of jack is ideal for applications that cannot accommodate a screw protection tube.

Up and down at the same time , and rotate in the same section . Arrangement recommends no more than 400MM in one minute. If the connecting shaft is used in arrangement with more than 1.5 meters, it is recommended to use a Trunnion. It is suitable for industrial applications in a variety of industries, with a variety of combinations and flexible operation.
