Screw jacks come in many forms. The basic principle of converting rotary motion into vertical or horizontal movement is always present, yet they can be as simple as a hand wheel driven single unit up to linked multiple motorized units lifting many tonnes whilst keeping the load stable and level.
The nut that travels up and down a screwed rod can be a relatively simple brass machined piece or a precise ball screw running on a machined shaft for high speed and 100% duty (continuous use), and motors are available in single or three phase AC, or DC for the smaller capacity screw jacks.
With lifting capability up to 20 tonnes per unit and lengths up to 10 metres per screw, please speak to us with your application needs for the best options most suited to you.
