A load carrying dolly for supporting and transporting items such as trash receptacles comprises a thin generally planar base formed with a peripheral series of holes with guiding posts extending upward through the holes above the upper surface of the base to centrally locate the receptacle and prevent lateral displacement. A second series of holes is provided near the margin of the base and peripheral to the first series of holes to receive the sockets of post-type casters, with the upper ends of the sockets extending above the base. To prevent separation of the caster posts from the sockets as a result of rough handling, securing means are connected to the upper ends of the posts and are considerably larger than the inside diameter of the sockets so that the posts are prevented from being inadvertently displaced. The securing means can have a portion which restricts the flaring of the end of the sockets to prevent separation of the caster posts.
