JACTON
Product Description
Stainless Steel Screw Jack 20 Ton-65x12-Self-locking Trapezoidal Screw. Stainless steel screw jacks are specifically designed for positioning and lifting applications that are located in wet, corrosive and harsh environments. Metallurgical properties of stainless steel allow it to remain ductile even at very low temperatures. These mechanical jacks are available in 1 ton through 35 ton capacities. Upright or inverted jacks operate at full capacity in tension or compression.
Main Features
* Maximum static load capacities 20 ton.
* Self-locking trapezoidal screw sizes Tr 65x12.
* Two gear ratios: high ratio 8:1, slow ratio 24:1 for high and slow linear speeds.
* Custom stroke length, maximum stroke 4000 mm in compression load, 5000 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 operated by hand wheel crank , electrically by motor (ac or dc) 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.
* Can be used as alternatives to hydraulic and pneumatic systems.

Application Case
The entirely stainless steel worm gear screw jacks has been designed specifically for the tough requirements of e.g. modern paper machines. This new series is based on a standardized construction kit, which may be combined individually. Due to high-grade stainless steel and innovative technology there should not be any obstacle anymore to a mechanical lifting solution in the field of steel hydraulics construction, food industry as well the explosion-proof area. Wherever it is necessary to lift important loads, adjust heights or format changes in automatic machines for plastics, metals, food, textile, printing, packaging, labeling, filling, assembly lines, lifting/adjustment platforms, elevation/lifting mechanisms.
