| 100 Ton Machine Screw Jack is used wherever fixed to controlled lifting, lowering, tilting, and slewing movements are required in an safe and reliable operation. Screw Jack are available in one of four standard end conditions. Worm gear screw jacks are very good in multiple jack systems, because the torsional deflection of connecting shafts and couplings has little effect on positioning. Under heavy load, worm gear screw jacks are not designed for high use or heavy duty cycle applications. They also suffer from low travel rates or speed and low efficiency. However, the lack of efficiency inherent in worm gearing produces the self-locking benefit associated with worm gear screw jacks. | |||||||||

JACTON
Product Description
Classic Machine Screw Jack 100 Ton-160x24-Trapezoidal Screw. The most common jack is the worm gear screw jack, also referred to as machined screw jacks because the acme, or trapezoidal, lead screw is machined. In addition to the low cost and self-locking characteristics, another advantage of worm gear screw jacks, and all screw jacks, is the mechanical advantage achieved through the internal gear ratio resulting in the ability to lift, lower, push or pull a significant load with a relatively small amount of torque on the worm shaft.
Main Features
* Maximum static load capacities 100 ton.
* Self-locking trapezoidal screw sizes Tr 160x24.
* Two gear ratios: high ratio 12:1, slow ratio 36:1 for high and slow linear speeds.
* Custom stroke length, maximum stroke 9000 mm in compression load, 12000 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: manual operation with hand wheel and crank handle, electrically by motor drive, 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.
* Custom double clevis screw jack, trunnion mount screw jack, and anti-backlash screw jack.
* Can be used as alternatives to hydraulic and pneumatic systems.

Application Case
Worm gear machine screw jacks are prefabricated parts used in engine construction and plant engineering. They are used in presses, elevating platforms, jack-up platforms, theater stages, working platforms, hoisting tackles, roll adjustments, feeding attachments, tipping devices, work benches, and loading platforms. They are also used as driving mechanism for shutters, slides, landing stages, lock-gates, in airport technology etc. Expediently design, precisely manufactured according to the latest standards highly efficient and long-lasting, spindle gears type jacton worm gear screw jacks are holding an irreplaceable position in the market and have become a fundamental building block for the constructing engineer of today.
