A stand providing a horizontal support surface upon a sloping peak includes a central support having a top surface and bottom surface with opposing end portions, and adjustably extendible legs attached in spaced relation to the bottom surface of the central support and end supports. The central support and end supports are connected by a hinge having a range of motion limiting upward movement of the end supports to a horizontal position with the central support. Each of the central and end supports have spaced adjustably extendible legs attached to the bottom surface whereby the central support and the respective end supports can be aligned to provide a horizontal support surface on a sloping peak by adjustment of said extendible legs, regardless of the angles of declination from the peak.

An articulated adjusting foot including a base plate having a receiving space on the side of the plate remote of the floor and which has the geometry of a partial ball, preferably with dimensions slightly exceeding a hemisphere, further having a threaded rod which has at its one end a partial ball that can be inserted into the receiving space. The partial ball of the threaded rod can be fittingly received in the receiving space. The threaded rod is a conventional screw bolt with hexagon head. The ball, which can be inserted into the receiving space, is formed of two parts, e.g., halves (half-shells), which can be inserted one into the other and which enclose the hexagon head in a torsionally rigid manner. The geometry of the partial balls of the threaded rod exceeds that of the receiving space axially in direction of the threaded shaft.

A support pad including a body and a washer for supporting a leg is provided. The body includes a bottom and an opposed top defining a top external surface. The body has a central portion defining a spherically shaped pocket formed in the top of the body. The central portion receives a spherically shaped end of the leg and defines a central axis of the body. The body also has a dome shaped intermediate portion extending radially outward from the central portion. The body further has an outer portion extending radially outward from the central portion. The bottom includes a support pad support surface. The dome shaped intermediate portion has a uniform wall thickness. The washer is positioned adjacent the top external surface of the body and has an inner surface defining a central opening in the washer.

A support for supporting a structure on a surface, comprising at least one support element, each support element comprising a piston, a cylinder in which the piston is moveable, and a brake for maintaining the piston in a position that is stable relative to the cylinder, wherein the piston and the cylinder are arranged so that a loading associated with the structure effects an adjustment of the support element, and wherein an increase in hydraulic pressure within the cylinder, effected by the loading associated with the structure, activates the brake.
