Screw jacks
EFFICIENT LOAD MOVEMENT | 250kg – 100t
ZIMM screw jacks | Key benefits for every use
ZIMM screw jacks are used for the precise lifting and positioning of components or loads. Versions with rotating R-screw and translating S-screw are available. The range includes the ZE-Series, ZE-H Series and GSZ-Series. Depending on the area of use and application, sizes with lifting forces from 2.5 kN to 1000 kN are available.

With their performance, accuracy and economy, screw jacks outperform hydraulic solutions in more and more applications. ZIMM screw jacks also shine with a number of features that they already have in the basic equipment ex works.
General technical information
Spindle with trapezoidal or ball thread
High performance gearing
Standardised flanges and matching parts
Corrosion protection ex works
Integrated sliding swivel bearings
Sealed gear
Lubrication without downtimes
Ready for all installation positions
Electromechanics vs. Hydraulics
In a direct technology comparison, electromechanical screw jacks are increasingly replacing classic hydraulic solutions in modern industrial plants. The following comparison shows the clear advantages of ZIMM screw jacks in the areas of cost-effectiveness, precision, and operational reliability:
| Criterion | ZIMM Electromechanics | Hydraulics |
| Energy Efficiency | High – energy only on demand | Continuously running pump |
| Positioning Accuracy | Micron-precise, repeatable | Leakage affects precision |
| Maintenance Effort | Minimal, no fluid management | High – oil, filters, seals |
| Environmental Compatibility | No leakage damage, leak-free | Risk of oil contamination |
| Installation Effort | Compact, easy integration | Complex piping & seals |
| Operational Reliability | No fire hazard from oil | Fire hazard in case of leaks |
| Synchronization | Multiple axes precisely synchronizable | Complex, vulnerable to pressure drops |
| Operating Noise | Quiet, no hydraulic pump | Loud due to pump aggregates |
| Controllability / Digitalization | Simple PLC integration, Industry 4.0 | More complex, analog character |
| Cleanliness / Hygiene | Ideal for cleanrooms & food industry | Oil residues are problematic |
Functionality | Rotating and translating spindle
R-Screw | rotating
The spindle is fixed to the worm wheel and rotates with it. The nut therefore moves up and down.
S-Screw | translating
The worm wheel has an internal thread and transforms rotary motion into linear movements as long as the spindle is prevented from rotating.
Possible combinations | ZIMM modular system
The ZIMM modular system complements screw jacks with suitable accessories for rotating R-screws and translating S-screws. Depending on the version and application, the selection includes mechanical fixing, joint, protection, safety and monitoring elements.
Areas of use and applications
ZIMM screw jacks are used for the precise lifting, lowering, positioning, and adjusting of components or loads. They are suitable for applications where reproducible linear motion, robust mechanics, and controlled integration into machines or systems are required.
