Aspects of the disclosure relate to trailers having an extendable boom on which sections of pipe or the like can be supported for transport and lift at a job site, such as an oil rig. The boom has a rearward portion and a forward portion. The forward portion is configured to fold under the rearward portion in a folded arrangement and can pivot away from the rearward portion into an extended, unfolded arrangement. In this way, an effective working length of the boom can be extended/shortened while the boom is in full operation and without having to separately transport and maintain an extension for the boom.
