Screw Jacks are the ideal product to push, pull, lift, lower and position loads of anything from a couple of kg to hundreds of tones. The need has long existed for an improved portable jack …
In this modified design, the power screw is rotated through its gear when electrical power flows through it. The main advantages of the modified design over the existing design are that the modified designed motorised jack will save time, be faster and easier to operate and requires less human energy and additional work to operate. There by effectively curb the problems associated with

design of the power screw may be such that (a) Either the screw or the nut is held at rest and the other member rotates as it moves axially. A typical example of this is a screw clamp. (b) Either the screw or the nut rotates but does not move axially. A typical example for this is a press. Other applications of power screws are jack screws, lead screws of a lathe, screws for vices, presses etc
For higher duties ball screw jacks or roller screw jacks are available – the roller screw jack is suited to very high loads. Construction of these units is available in standard materials or corrosion resistant eg complete stainless steel jacks. The E-Series screw jacks design is fully customisable by our engineering team to meet your exact application requirements.
