A gantry 1 has a pair of supports 2 for supporting a beam 5. Each support 2 has a support frame 3 and a beam support, such as a cradle 4, which is mounted on the support frame 3 so as to be turnable, possibly using elongate slots (22, fig. 6). Each support frame 3 comprises a pair of side arms 8, a base 7 extending between the side arms 8, and a ground engaging stabiliser (28, fig. 7) extending from the base. The beam support or frame may have one of tubular members 9, 10, where the radially inner member 10 may turn, the members forming a central mast 6. The support frame may have side arms 8 being pivotally connected to the beam support and may be height adjustable. The support frame may also have wheels (30 fig.9) which may be configurable for ground engagement or not. A pair of bags with wheels may be provided to transport a dismantled gantry; each support weighing less than 80Kg.
