Abstract
A telescopic beam comprises a plurality of telescopically-interconnected members which define rails along which a load-carrying tub can move. Means are provided for locking the telescopic members together. The beam is provided with a pair of tensioning cables which bridge several of the telescopic members. The cables are guided by means of spacers attached to the telescopic members.
