An extensible outrigger construction comprises a tubular housing secured to a vehicle frame, having an outrigger beam telescoped into it. The outrigger beam comprises upper and lower horizontal plates with semicircular cut-outs at their ends to receive the cylinder of the jack; a pair of vertical flange plates have surfaces on a diametral plane of the cut-out. A cap includes upper and lower horizontal plates with semi-circular cut-outs, and vertical flange plates engaging the first mentioned flange plates, the holding cap being secured by bolts through the flange plates. The jack cylinder has an upwardly facing shoulder that engages the bottom surfaces of the lower beam plate and the lower plate of the holding cap. The cylinder of the jack has a chamfer which seats in a corresponding chamfer of the top plates.
