Product Description
Cubic Compact Screw Jack 50kN-40x7-Trapezoidal Screw. Cubic Screw Jacks are used wherever controlled lifting, lowering and slewing is required. They can be installed singly, in pairs or as part of a multiple jack system.
Translating (Basic) Version: (rising spindle) the spindle provides the linear motion. In this design the spindle moves axially through the jack nut. Rotation of the spindle must be prevented; usually by fixing the end of the spindle to the item being moved.
Rotating (Travelling nut) Version: the spindle is axially fixed and linear motion is transmitted to the running nut by rotation of the spindle. The nut must be secured against rotation by fixing to the item or mechanism being moved.
Main Features
* Maximum static load capacities 50 kN (5 ton).
* Self-locking trapezoidal screw sizes Tr 40x7, 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 3000 mm in compression load, 4000 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.
