Abstract
A method of collecting refuse including the steps of moving a first semi-trailer having a frame carrying a refuse collection body to a transfer site and coupling it to a fifth wheel of a vehicle. Refuse is deposited into the refuse collection body by engaging a refuse container with a loading mechanism carried by one of the first semi-trailer and vehicle. The first semi-trailer is then uncoupled from the vehicle at the transfer site and a second semi-trailer is coupled to the vehicle for further refuse collection. The second semi-trailer is returned to the transfer site and uncoupled. The first and second semi-trailers are then transported to a disposal site by coupling the vehicle to the first semi-trailer and attaching the second semi-trailer to a dolly. The dolly is coupled to the first semi-trailer.
