Abstract
A lightweight, compact, portable pull-testing device is disclosed which is especially adapted for testing the load capabilities of installed, relatively small earth anchors such as those utilized with hold-down equipment for mobile homes or the like. The device includes a tripod-mounted, vertically adjustable, hydraulically actuated piston and cylinder assembly securable to the upper protruding end of an earth anchor shaft, with generally upright tripod support legs positioned closely adjacent the protruding shaft end to permit use of the device by a single operator in crowded areas such as beneath a mobile home where space is at a premium. Novel creep indicator apparatus is also disclosed for the accurate measurement of anchor creepage independent of any settling of the device itself into the earth which may occur during pull testing.
