Manufacture and Sale Manual Worm Screw Jack Actuator Crank Table Mechanism Hand Crank Table Lift Mechanism, Manual Screw Jacks | Adjustable And Light Weight. Hand crank self locking lift table jacking 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.
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 are utilized in various applications where there is a need for accurate lifting, lowering, pulling or pushing. Manually or electrically-operated versions are also available, with capacities up to 1000 kn and a spindle length of 10 meters. These devices are designed with a built-in structure, in order to make any required combinations and variations. These can be constructed in various special materials to allow their use under mechanical conditions. SCREW JACK SERIES * Worm gear screw jack * Loads up to 100 tons * Ratio 5:1 to 40:1 * Driven manually or by motor * Aluminum bronze worm gear * Self-locking safety feature * Heavy duty cast iron housing * Versatile configurations and mounting * Low noise * One year limited warranty Mechanical jacks are absolutely irreversible, meaning they can support their loads with no need to employ brakes or other locking systems. The screw jacks can be deployed individually, or in groups connected properly with shafts, joints, and/or bevel gear boxes. They can be driven by electrical motors, with either alternating or direct current, as well as hydraulic or pneumatic motors. They can be driven manually, or with any other type of transmission. All screw jacks are available in a basic version and a travelling nut version, and can be supplied with either an upright or inverted spindle.
