Description:
We are manufacture and sale Hand Operated Screw Jack with Handle or Crank Hand Wheel Screw Lift Mechanism for Crank Table, hand wheel screw jack worm gear screw lifting mechanism. hand crank jacks actuators systems lift 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.

The generic term "screw jack" or jackscrew generally refers to a product that utilises a gearbox assembly and a transmission medium (lead screw, ball screw or roller screw) which, through the use of a motor or hand wheel, converts this rotary motion into linear motion.
Screw jacks are suited for lifting, lowering, pushing, pulling and pressing. They can be operated manually or by electric, hydraulic or pneumatic motor. Screw jacks provide a lifting force of up to 100tons/1000kN, a spindle length of up to 10 metres and achieve lifting speeds of up to 50 mm/s. (higher lifting speeds upon request).
Screw jacks transform the rotatory movement provided by an electric, hydraulic, pneumatic or manual motor into a linear motion: a vertical lifting, in pull or push, or an 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 to have perfectly balanced systems even with loads not perfectly distributed on the surface.
