Manufacture and Sale Manual Machine Screw Jack Industrial Crank Table Base Crank Desk Industrial Adjustable Jack Crank Table, manual screw jack lift mechanism. hand crank gear jack desk lifting mechanism includes two 2.5 ton screw mechanisms for crank table base, four 2.5 ton screw mechanisms for crank table base, and two 5 ton screw mechanisms for crank table base. All our screw mechanisms have self-locking function, don't require any lock mechanism, they will hold and stop any position without turning hand crank.
* Crank Screw Lift Mechanism 2.5-Ton Kit with Two Lifting Points (Small-Size, or Normal Table Base) is consist of two pieces 2.5-ton screw mechanisms that support and adjust height, two pieces 200mm diameter handwheel (cast iron), two pieces couplings and one piece connecting rod.
* Crank Screw Lift Mechanism 2.5-Ton Kit with Four Lifting Points (Big, or Super-Big Table Base) is consist of four pieces 2.5-ton screw mechanisms that support and adjust height, two pieces 300mm diameter handwheel (cast iron), four pieces transmission gears, four pieces couplings and two piece connecting rods.
* Crank Screw Lift Mechanism 5-Ton Kit with Two Lifting Points (Normal, or Big Table Base) is consist of two pieces 5-ton screw mechanisms that support and adjust height, two pieces 300mm diameter handwheel (cast iron materials), two pieces couplings and one piece connecting rod.
Important Note: Avoid slow lifting speed, we provide double lead screw mechanism, which is two times faster than normal single lead screw mechanism. Important Note: Connecting rod length 36", 43", 48", 52", 60". Can be customized. Important Note: Height adjustment 8", 10", 12", 14", 16", 18", 20". Can be customized. Important Note: Handwheel diameter 6", 8", 10", 12", 16". Important Note: Paint color: no paint, black, blue, grey. Important Note: Available in electric motorized screw lift mechanism with single phase motor, dc motor or electric hand driller.
Operation can be either manual or motorized. Screw Jack can be used as single units, in dual or multiple arrangements. Motion uniformity is warranted also when operating multiple Jacks of different sizes with uneven load distribution. worm gear screw jack or worm screw jack is a mechanical motion control device used for lifting heavy weight objects, push or pull an object. The key components of screw jacks are trapezoidal lifting screw, worm screw, worm gear and gear housing. Worm screw is rotated manually (manual screw jack) or by a motor (electric screw jack).
Screw jacks transfer the rotatory movement provided by an electric, hydraulic, pneumatic motor, or handwheel into a linear motion: a vertical lift, in pull or push, or horizontal positioning. They can be used individually or in configurations made up of several screw jacks coupled together through couplings, transmission shafts and bevel gearboxes. Screw jacks allow perfectly balanced systems even with loads not perfectly distributed on the surface. All available with motors if required.
