| Compact precision screw jacks are specifically designed to provide highly precise lifting, lowering and pivoting of loads. These units feature a cubic housing (machined on all sides) made out of high quality grey cast iron, ensuring excellent durability and long service without any need for maintenance (under normal operating conditions). The motor and screw jack assemblies were designed for installation in any position, while the unique form of the worm gearing helps reduce inter-gear specific pressures, and further improves durability. The worm unit is made out of hardened and ground alloy steel of top quality. | |||||||||

Product Description
Cubic Compact Screw Jack 100kN-55x9-Trapezoidal Screw. The cubic-type screw jacks are lifting elements that have enjoyed great popularity among users for decades due to their shape and characteristics. The screw drives from our own production, paired with high-quality worm gearboxes, result in screw jacks with outstanding properties in terms of lifting power and smoothness. The cubic design enables the use of the screw jacks in all mounting positions. As an Translating version with continuous spindle or as an Rotating version with rotating spindle in combination with a running nut, the screw jacks can be assembled for the respective application.
Main Features
* Maximum static load capacities 100 kN (10 ton).
* Self-locking trapezoidal screw sizes Tr 55x9, precise positioning, and uniform speed.
* Three gear ratios: high ratio 1:7, medium ratio 1:14, slow ratio 1:28.
* Custom stroke length, maximum stroke 3500 mm in compression load, 4500 mm in tension load.
* Basic designs: Translating screw, Keyed screw, and Rotating screw.
* Upright or Inverted mounting. Available in tension or compression loads.
* Standard with 1-start thread screw, custom 2-starts threads screw which offers increased travel speed and require a brake or external locking device to hold position.
* Screw end fittings: top plate, clevis end, threaded end, plain end, fork head and rod end.
* Power source: manually by hand wheel, electrically by motor driven, or both together.
* Can be applied either individually use or combined into a exactly synchronized lifting system (multiple jack systems), linked by connecting shafts, bevel gearboxes, couplings, electric motors, gear reducers, limit switches and pillow blocks etc.
* Can be used as alternatives to hydraulic and pneumatic systems.

Application Case
These compact cubic worm gear screw jacks are used in many fields where it is necessary to lift considerable weights, such as automated production lines for sheet metal machinery, packaging, printing, textiles, plastics, food, renewable energy and more. For example: Atomisers and sprayers: adjustment and orientation of devices used for spraying. Harvesting machines: platform vertical positioning. Irrigation systems: control of the opening/closing of valves for the water flow. Mobile robots for breeding/zootechnics (for the distribution of forage): control of AGV steering and direction, vertical positioning of the platform for the material loading/unloading. Ambulance stretchers: lifting of the stretcher. Vehicles for people with a reduced mobility capacity: automation of the opening/closing of doors and platforms for the wheelchair pick-up/drop-off. Photovoltaic panels and solar concentrators: inclination and rotation to optimize the solar tracking process. Dams: automation of the opening/closing of bulkheads for the water flow regulation etc.
