Double Clevis Features

When freedom of movement in two axes is required, a double clevis jack may be specified. A double-clevis jack incorporates a special clevis end bottom pipe and a standard clevis end on the lifting screw. Machine screw and ball screw jacks from 1 ton to 50-ton load capacities can be supplied with double clevis mounts. Applications like angle tilt adjustments, moving a load through an arc, tracking antennas, hinged doors or air dampers etc is more common.

Below are some application examples. Please consult [email protected] for more information and help.

Please NOTE:

  • It is used only direct compression or tension loads, thereby eliminating side load conditions.
  • Double clevis jacks are always made from upright jacks.
  • Double-clevis jacks are limited both in capacity and maximum length.  Since this structure tends to weaken it as a column by creating eccentric loads on the screw. This eccentricity is more likely to increase with greater distance and higher loading.
