A telescopic lifting frame or spreader for enaging, lifting and transporting freight containers by means of van carriers, lift trucks, and the like, having a longitudinal coaxial telescopic beam structure extensible the distance of about twice its collapsed length and having freight container corner casting engaging hooks which engage from the sides of the container. Opposed spreader beams are telescopical coaxially in and out of each other and are supported from and telescoped in a fixed center beam. When associated with a van carrier machine frames are provided for connecting the spreader to the side frames of the carrier for guided elevation relative thereto, as well as for guiding, skewing and side shifting of the spreader in the bay of the carrier and means compensating for carrier side frame deflection. In addition, positive locking means engages beam structure at various selectable lengths thereof, and an interior beam extension structure is connected to the opposed beam ends in a manner to provide a minimum collapsed length of the lifting frame or spreader for the maximum available extended length thereof.
