ABSTRACT:
A temporary, self-leveling support device is provided having a screwjack body with a threaded hole formed centrally therein for engaging a threaded bolt. The bolt has a load bearing plate affixed thereon. The bolt can be rotated within the screwjack body to raise or lower the load bearing surface. The screwjack body has two opposed support legs pivotally attached thereto which extend down to form an A-frame support. The support legs have pivtotally mounted feet which can pivot to engage uneven surfaces thereby allowing the device to be self loading. The legs are secured to each other by an adjustable tie bar cross member which can be adjusted to increase or decrease the distance between the support legs and thereby adjust the overall height and base dimensions of the device.
