<p>A levelling foot for a scaffold structure comprises a ground engaging tubular member (28) having an axially adjustable rod (36) contained therein which carries the weight of the scaffold structure thereon. The rod (36) includes a bracket and spigot (38, 40) at its lower end projecting through a slot (32) in the tubular member (28) and adjustment means in the form of a link chain or a coarse pitch screw. The weight of the scaffold structure is supported on the rod bracket and spigot (38, 40) so that the rod (36) is only under tensile loading whilst the tubular member (28) is under compressive loading.</p> |
