Product Description

The screw jack makes it possible to transform the rotary motion provided by an electric, pneumatic, or hydraulic motor or even a handwheel, into linear motion that allows push or pull vertical lifting and horizontal positioning. They can be used to lift, pull, move, or align any type of load with perfect synchronism, which is difficult to achieve with other types of actuators.They can be applied either with vertical mountings facingup or down, or with horizontal mountings.
The screw jack is a device for lifting heavy loads by applying comparatively small at its handle. If the free shaft end of the motor is used as shaft for a slip-on emergency hand wheel, a device will be required that interrupts the power supply before the crank engages. 
Screw jacks come assembled, threaded, and ready for hookup. Connect a motor or hand-crank shaft to the screw jack shaft to lift, hold, position, and level loads.

All JACTON screw jacks with handwheels 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. Available in load capacity 1/4 ton, 1/2 ton, 1 ton, 2 ton, 2.5 ton, 3 ton, 5 ton, 10 ton, 15 ton and 20 ton, heavy load larger than 20 ton capacity, handwheel manual operation is not recommended. There are two types hand wheels, one is cast iron handwheels, another aluminum handwheels. The cast iron handwheels sizes 100mm, 125mm, 160mm, 200mm, 250mm, 300mm, 400mm and 500mm. The aluminum handwheels sizes 100mm, 125mm, 160mm, 200mm.

The most common jack is the worm gear screw jack, also referred to as machined screw jacks because the acme, or trapezoidal, lead screw is machined. In addition to the low cost and self-locking characteristics, another advantage of worm gear screw jacks, and all screw jacks, is the mechanical advantage achieved through the internal gear ratio resulting in the ability to lift, lower, push or pull a significant load with a relatively small amount of torque on the input/output shaft. Worm gear screw jacks are very good in multiple jack systems, because the torsional deflection of connecting shafts and couplings has little effect on positioning. Under heavy load, worm gear screw jacks are not designed for high use or heavy duty cycle applications. They also suffer from low travel rates or speed and low efficiency. However, the lack of efficiency inherent in worm gearing produces the self-locking benefit associated with worm gear screw jacks.
