Manufacture and Sale Small Crank Jacks Adjustable Jack Screw with Manual Crank Lift Manual Adjustable Screw Actuators, Mechanical Crank Table Base, Hure Crank Table Base. hand crank screw lift system 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.
Screw Jack Systems center around an electromechanical drive system, handling load capacities from just a few pounds to 100 tons and moving these loads, no matter what the size with precise positioning and accuracy.
They can be used individually or in configurations composed of multiple jacks connected together by means of bevel gearboxes, drive shafts and couplings allowing the creation of perfectly balanced lifting systems and drives even with unevenly distributed loads. They can be used to lift, pull, move, or align any type of load with perfect synchronism, which is difficult to achieve with other types of actuators.They can be applied either with vertical mountings facingup or down, or with horizontal mountings. When creating a multi-jack system, pay attention to the system's rotation direction. We recommend consulting our standard assembly diagrams. (In the case of 3-way bevel gearboxes, the direction of rotation can be changed simply by rotating the gearbox. In multi-jack systems, parallelism must be guaranteed between one jack and the next. Parallelism errors can compromise correct operation of the system, causing overheating, premature wear or failure. During commissioning of the jack or system, a series of checks must be carried out following the instructions in the use and maintenance manual.
