2.5 Ton Machine Screw Jack

Brand: JACTON

Model: JTW-2.5T

Brief:
All metric 2.5 Ton Machine Screw Jacks have a trapezoidal thread form. For loads of 25% to 100% of screw jack capacity, torque requirements are approximately proportional to the load. Efficiency values for standard grease lubricated worm gear box and lifting screw. All screw jacks have grease lubricated gearbox and lead screw as standard. Machine screw jacks can be fitted with a safety nut. In the event of excessive wear on the nut thread the load will be transferred from the standard nut to the safety nut.

5 Ton Machine Screw Jack

Brand: JACTON

Model: JTW-5T

Brief:
5 Ton Machine Screw Jack Actuator Advantages: Positive, mechanical positioning, Uniform lifting speed, Multiple arrangements, Anti-backlash feature (optional). Precise Positioning -Can be controlled accurately for positioning within thousandths of an inch. Self Locking -Will normally hold loads in position without creeping when using the higher ratio units, as long as the actuator unit is not subject to vibration. Uniform Lifting Speed -Since many models have the same gear ratios, various capacities can be used in the same application to lift unevenly distributed loads with uniform speed.Quick, Sure Operation -Designed and built to be positive acting, for accurate response to motive power. Anti-Backlash Option -Reduces vertical backlash between the screw and the worm gear nut to a practical minimum for smooth, precise operation and minimum wear.

10 Ton Machine Screw Jack

Brand: JACTON

Model: JTW-10T

Brief:
The worm gear driven 10 Ton Machine Screw Jack incorporates an alloy steel worm which drives a high strength bronze worm gear (drive sleeve). The worm shaft is supported on anti-friction tapered roller bearings with external seals provided to prevent loss of lubrication. The drive sleeve is supported on anti-friction tapered roller or ball thrust bearings. Rotation of the drive sleeve causes the acme thread lifting screw to translate or rotate, depending upon jack configuration. The jack housing is made of ductile iron and proportioned to support the rated capacity of the unit.

15 Ton Machine Screw Jack

Brand: JACTON

Model: JTW-15T

Brief:
Approximately 50% of 15 Ton Machine Screw Jacks are self-locking either in the gearbox or the lifting screw, however to ensure there is no self lowering and to reduce drift due to the motor slowing, a brake is recommended. Standard motor frame size brakes will be suitable for most applications with only slight vibration and thermal fluctuation present. Motor selection as normal. Use the closest standard brake size that is greater or equal to the motor brake torque required.

50 Ton Machine Screw Jack

Brand: JACTON

Model: JTW-50T

Brief:
50 Ton Machine Screw Jack incorporates a machine cut lead screw in order to transfer rotational energy in to linear energy. The rotation of the worm screw acting on the lead screw via the worm wheel converts rotation in to linear motion. Available in a comprehensive range of materials and fittings with the option for special designs for specific application requirements. They are used in wide variety of automation applications including those in steel, automotive, communications, civil, defence, energy, glass and aerospace sectors.

100 Ton Machine Screw Jack

Brand: JACTON

Model: JTW-100T

Brief:
100 Ton Machine Screw Jack is used wherever fixed to controlled lifting, lowering, tilting, and slewing movements are required in an safe and reliable operation. Screw Jack are available in one of four standard end conditions. 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.
