Classic industrial style Hand crank screw positioning table. Manufacture and Sale Mechanical Screw Jack Adjustable Desk Table Height Adjustment Hardware Crank Shaft Coffee Table, crank height adjustment mechanism, manual screw jack lift. Hand crank screw positioning 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.
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.
One of the most familiar kinds of jackscrews are the traditional manually powered, hand-turned types, which operate by applying force against a handle which makes the screw rise from a base unit, lifting or lowering a load. Other common means of driving jackscrews are either ac or dc motors. Lifting and actuation systems, screw jacks is a modular mechanical system, for a complete and versatile solution, which transforms rotary movements into push/pull linear movements. * Trapezoidal screw in AISI 304, stainless steel, * Case in anodized aluminium, shafts and gears treated with wear-resistant surface hardening * Trapezoidal screw with non-standard lenghts in mm * Maintenance-free: lubricated with long-life by grease * Can be used individually or combined using flexible shafts, couplings and gearboxes * Manual or motorized motion * Possibility to apply a display unit * For applications with displays, motors, multiple screw jacks and combinations with flexible or rigid shafts and gearboxes. There are many possibilities of application: 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.
