Abstract
The present invention provides a dolly (10) having a deck (12) including a plurality of rotatable members (14) secured thereto to support the deck (12) relative to a support surface (16) and enable the dolly (10) to move on the support surface (16). Each rotatable member (14) has a skirt element (24) located adjacent thereto. The or each skirt element (24) is movable relative to the deck (12) between a first position in which each rotatable member (14) is exposed beyond the adjacent skirt element (24) to a first extent and a second position in which each rotatable member (14) is exposed beyond the adjacent skirt element (24) to a second extent. The second extent is less than the first extent. Movement of the or each skirt element (24) between the first and second positions selectively engages a brake (50) to inhibit movement of the dolly (10) relative to the support surface (16).
