Industrial Screw Jacks for Lifting and Positioning

Screw jacks are gearbox assemblies combined with transmission components that, through the use of a motor, can be used to convert rotary motion into linear motion. Lude Transmission supplies industrial screw jacks for lifting, lowering, positioning and load adjustment in industrial machinery and automation systems. Our product range includes trapezoidal screw jacks, ball screw jacks, cubic screw jacks, electric screw jacks, manual models and stainless steel designs for different operating conditions.

Depending on the application, screw jacks can be used to lock, unlock, push, pull, tension, tilt, lift, lower, slide, roll, or pivot loads ranging from a few kilogram up to 120 tons.

Features

• No "standard" travel lengths (built to specification).
• Ductile iron housings proportioned to support the rated capacity of the unit.
• Use individually or in multiple screw jack arrangements.
• Alloy steel worm drive with high strength bronze worm gear
• Anti-friction tapered roller bearings with external seals to prevent loss of lubrication.
• The drive sleeve is supported on anti-friction tapered roller or ball thrust bearings.

Options

• Protective boots available

• Customized mechanical jacks can be made to your specifications

FAQ

1. What is an industrial screw jack used for?

An industrial screw jack converts rotary input into linear movement for lifting, lowering, positioning or adjusting loads. The suitable configuration depends on the load, stroke, speed and operating conditions.

2. What is the difference between a ball screw jack and a trapezoidal screw jack?

Ball screw jacks generally offer higher mechanical efficiency and are suitable for applications requiring faster movement. Trapezoidal screw jacks may be suitable for applications prioritizing load holding and simpler configurations. Selection depends on the specific design and operating conditions.

3. Can screw jacks be used in a synchronized lifting system?

Yes. Multiple screw jacks can be connected through a suitable mechanical drive system or coordinated control system. The design must account for load distribution, alignment, travel synchronization and safety requirements.
