Manufacture and Sale Manual Crank Screw Jack Gear Lift Mechanism Industrial Hand Crank Desk Mechanism, Hand wheel screw jack, Hand Operated Screw Jack, hand crank lift mechanism. hand crank precision lifting table 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 screw jacks can be employed singularly or in groups properly connected with shafts, joints, and/or bevel gearboxes. They can be driven by different motors: electrical, with either alternating or direct current, as well as hydraulic or pneumatic motors. Also they can be driven manually or with any other type of transmission. In addition to the models shown on the following pages, we can produce custom designed screw jacks to meet all the requirements. They can be driven by different motors: electrical, with either alternating or direct current, as well as hydraulic or pneumatic motors. Also they can be driven manually or with any other kinds of transmission. Our ball screw jacks are designed and manufactured using innovative technology so to supply a product which identifies itself with the state of the art in the transmission devices.
Trapezoidal Screw Jack Original modular design, biomimetic surface with owned intellectual property right. Low friction, long life cycle, high efficiency. Diverse drives, motor or other power drive, also can be driven by hand. Various output type. Mounting mode: foot mounted, base support mounted, legs and base support mounted. Structure mode: plain mode, with anti rotation device, with structure traveling nut. Main applied for Hoist and transport, Building and construction, Forest and paper, Metal processing, Agriculture and food.
