Abstract
Apparatus which renders a self-elevating drilling platform self-mobile on land and a method of moving the drilling platform employing the apparatus. The self-elevating platform includes a body, forward and rear legs, and means for adjusting the legs by moving the legs with respect to the body and moving the body with respect to the legs. The apparatus includes a launch pad which will be pivotally mounted to the platform beneath the body. In operation, the legs of platform are adjusted so that, alternatively, the launch pad swings forward beneath the body when the pad is elevated off the ground and the body pivots forward around the pad when the pad is on the ground.
