0.5 Ton Acme Screw Jack

Brand: JACTON

Model: JT-0.5T

Brief:
How Screw Jacks Work? Main components of screw jacks are trapezoidal lifting screw, worm screw, worm gear and gear housing. Worm screw is rotated manually or by motor. Worm gear is rotated by worm screw. The lifting screw moves through the rotating worm gear. The linear motion speed of lifting screw depends on thread size and rotation ratio of worm gears.

1 Ton Acme Screw Jack

Brand: JACTON

Model: JT-1T

Brief:
Broad, strong Acme threads make these screw jacks better than ball screw jacks for heavy loads, intermittent positioning applications, and where vibration is present. Screw jacks come assembled, threaded, and ready for hookup. Connect a motor or hand-crank shaft to the screw jack shaft to lift, hold, position, and level loads. Travel distance per turn, also known as screw lead, is the distance a load moves with one revolution of the shaft.

2 Ton Acme Screw Jack

Brand: JACTON

Model: JT-2T

Brief:
Worm gear screw jacks are very good in multiple jack systems, because the torsional deflection of connecting shafts and couplings has little effect on positioning. Under heavy load, worm gear screw jacks are not designed for high use or heavy duty cycle applications. They also suffer from low travel rates or speed and low efficiency. However, the lack of efficiency inherent in worm gearing produces the self-locking benefit associated with worm gear screw jacks.

5 Ton Acme Screw Jack

Brand: JACTON

Model: JT-5T

Brief:
Motor and screw jack assemblies can be installed in any position. The worm gearing has a specially modified form which results in low inter-gear specific pressures and an extended working life. The worm is manufactured from high quality alloy steel, hardened and ground. Normally the spindle pitch and gear ratio are matched. Single start precision trapezoidal screws are normally self locking. However safety regulations must be observed.

10 Ton Acme Screw Jack

Brand: JACTON

Model: JT-10T

Brief:
A trapezoidal screw or ball screw is combined with a worm gear in the construction of these linear jack actuators. Connecting these to a drive motor is all that is required in order for them to properly function. Machine, ball and high-lead ball screw types are all available for purchase. These machines use time-proven gear reducer technology as well as advanced screw technology.
