Abstract
A walking platform construction comprises a barge or work platform and a plurality of legs movable in a vertical direction and securable with respect to the barge or platform. The barge or platform has a plurality of independently movable auxiliary frames each comprising one or two legs movable and securable in vertical direction with respect to the auxiliary frame. Each auxiliary frame is disposed in a rectangular recess of the barge or platform and movable within the recess in the longitudinal direction of the recess as well as in a transverse direction. In the case in which the auxiliary frame is a long rectangular frame having two legs, each end of the frame has means to move this end in a transverse direction to the frame's longitudinal axis.
Claims4
A walking platform construction comprising a barge or work platform and a number of legs movable in a vertical direction and securable with respect to the barge or platform, a plurality of auxiliary frames disposed in a plurality of elongated rectangular recesses in the barge or work platform that are parallel to each other, first power means for shifting each auxiliary frame relative to the barge or platform in a horizontal direction parallel to the longitudinal axis of the recess relative to and independently of the other said auxiliary frames, second power means for shifting each auxiliary frame relative to the barge or platform in a horizontal direction at 90.degree. to said axis relative to and independently of the other said auxiliary frames, there being substantial clearance between each said auxiliary frame and the barge or platform in both said horizontal directions thereby to enable said shifting, each said auxiliary frame having at least one leg and means to move said at least one leg vertically relative to the associated said auxiliary frame.
