Of all the leveling devices, Wedge Jacks provide the most rigid support after adjustment. All jacks have mating parts with spherical seats that allow automatic adjustment for up to 7° of transverse compensation for uneven floors. The wedges move readily in response to turning the adjustment bolts.
Jacks are furnished without pads for leveling only or with 1/2″ 13mm thick oil resistant pads underneath to provide friction and vibration isolation. Economical two piece jacks have no provision for bolting. Equipment moves front to back during adjustment. Three piece jacks have a through hole for bolting and equipment moves only up and down during adjustment.
