<p>The specification describes a double dolly for use with a conveyor for moving an object by engagement with the object. The double dolly comprises a first roller which rotates about a first axle, a second support roller which rotates about a second axle, and a frame for securing the rollers and axles to a conveyor. The first roller which engages the object, is freely rotatable prior to contact with the object. The support roller is in contact with the surface over which the object is being moved for transferring load exerted on the dolly by the object to that surface while permitting movement of the dolly.</p> |
