A straddle carrier, between the side bodies of which a space is formed for the loads to be transported, particularly characterized in that its body consists of two opposed upper side bodies, which have been mutually connected by a transversal beam at their middle, and the driver's cab being placed upon this beam. By this arrangement, unobstructed forward and rearward visibility from the driver's seat is gained, in contrast with the design of prior art incorporating one transversal beam at the front and another in the rear. Further, optional characteristics specify that the transversal beam is of a box-type design and serves in the manner of a torsion spring to adapt the carrier to uneven driving surfaces; that the straddle carrier's power means (at least one engine) are placed below the upper side bodies, supported by separate lower side bodies; and that the upper surfaces of the upper side bodies are sloping for even more expanded visibility.
A straddle carrier comprising two spaced upper side bodies, the space between said bodies being used for the loads to be transported, a single transverse beam interconnecting said bodies and extending between opposed middle side portions of said bodies, a driver's cab carried by said beam, wheels and means connecting said wheels with said side bodies, said transverse beam being a box-type beam dimensioned to operate as a torsion spring, whereby simultaneous contact of all wheels with an uneven driving surface is achieved.
