We are manufacture and sale Hand Worm Gear Acme Screw Jacks Price Industrial Crank Dining Table Double Gear Mechanism, hand crank worm screw jack, crank table lift mechanism. hand crank screw lift mechanism drive 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.
With such a wide range of standard machine screw actuator configurations, we gives your design flexibility and economy. Examples of these standard options include upright or inverted screws with threaded or top plate screw end, as well as upright and inverted screws with top plate, keyed lifting screw, limit switches, IEC, NEMA C-face motor flanges and position indicators. Our machine screw actuators are available in standard models to meet almost any requirement. Capacities cover a wide range, from 1 to 100 tons. Operated manually or with air, hydraulic or electric motors, machine screw actuators can be used individually, in tandem or in multiple arrangements. Since most capacities have similar gear ratios, you can realize added economy by using different capacities in unison to raise unevenly distributed loads. Most higher ratio machine screw actuators are self-locking and will hold heavy loads indefinitely without creeping. However, if self-locking is absolutely necessary, a motor brake or other restraining device should be considered. They can be used to push, pull and apply pressure and position precisely.
A mechanical jack is used where precisely controlled linear movement and positioning are needed. We manufacture two main types of mechanical screw jacks, they are machine-screw jacks or ball-screw jacks. Axial machine screw, Rotary machine screw with travelling nut.
