200 kN Worm Gear Screw Jack-Trapezoidal Screw Type

Brand: JACTON

Model: JTM200

Brief:
Axially moving trapezoidal screw. Rotating trapezoidal screw with travelling nut. To determine the correct size of screw jack it is necessary to know the load and required lifting speed. A significant proportion of the applied power is used in overcoming the friction between the trapezoidal screw and nut. These losses are converted into heat, and therefore either the speed, load or duty factor must be limited in order to avoid overheating of the screw jack. For this reason ball screw jacks can be used – either at higher speeds or for higher duty factors. For screw jack arrangements in which several screw jacks, differential gears, couplings etc. are combined, regard must be paid to losses in the various elements and to alignment errors.
