Double Clevis Screw Jack

Double Clevis Screw Jack incorporates a special clevis end bottom pipe and a standard clevis end on the lifting screw. Double-clevis jacks have less load capacity than the other common mounting configurations. This tends to weaken it as a column by creating eccentric loads on the screw. This eccentricity tends to increase with greater distance and higher loading. For this reason, double-clevis jacks are limited both in capacity and maximum length. Double-clevis mounting differs from trunnion mounting because the pivot is located farther from the jack body. The Column Loading charts do not apply for this mounting.


These double clevis jacks are used when it is necessary to move a load through an arc, such as tracking antennas, hinged doors or air dampers. Double clevis jacks used horizontally will have reduced column strength and life. For most horizontal applications, we recommends the use of an Electric Cylinder. Machine Screw and Ball Screw Jacks from 1 tons to 20 tons capacities can be supplied with double clevis mounts. One clevis is mounted on the end of the lift shaft and the other clevis is welded to a heavy duty stem cover, which is welded to the housing. Double clevis designs are available with optional accessories such as boots, motor mounts, right-angle reducers, motors, encoders and limit switches.
