Industrial truck for picking up a laterally disposed load
First Claim
1. An industrial truck having a laterally extending contour and arranged for picking up a laterally disposed load, comprisinga chassis including two transversely extending chassis beams (6, 7) and a longitudinally extending beam (14), which connects the transversely extending chassis beams (6, 7),wheels (15 to 17), which are disposed under the chassis beams (6, 7) and at least one (17) is driven and steerable,a laterally extensible and retractable load carrier subassembly (8) comprising a forked load carrier including at least one load carrier arm (21, 22;
- 109),guiding means, which are provided on confronting sides of the chassis beams and adapted to guide the load-carrier subassembly on both sides in a lateral direction,an extending drive for laterally extending and retracting the load carrier subassembly beyond the laterally extending contour of the truck,stop means for limiting the extending and retracting of said load carrier subassembly,a lifting drive (37) for vertically moving the load carrier subassembly (8) relative to at least one said chassis beam,downwardly extensible load-supporting rollers (23, 24;
45,
46) adapted to be supported on the ground under the truck,which load-supporting rollers (23, 24;
45,
46) for supporting the load carrier arms (21,
22) are mounted on said load carrier arms (21,
22) and included in the load carrier subassembly,drive means for downwardly extending the load-supporting rollers (23, 24;
45,
46),guide tracks (18, 35,
36) on said chassis beams, and guide rollers (33,
34) for guiding said load carrier arms on said tracks and said guide rollers being upwardly displaceable from said guide tracks, said lifting drive (37) comprises a double-acting cylinder-piston device connected at one end to a fork crosspiece housing (11) which is included in said load carrier and carries said load carrier arms and at the other end to beam means extending through said housing and comprising a crossbar (30) and a transverse rod,said beam means carrying said guide rollers (33,
34) adapted to be supported on and to be lifted from said guide tracks (35,
36),slotted cam plates (40,
41) are carried by said beam means,pivoted arms for adjusting an adjusting linkage are guided in cam slots formed in said slotted cam plates and are connected to said drive for extending said load-supporting rollers (23,
24), andsaid fork crosspiece housing (11) is vertically movable relative to said beam means.

Abstract
An industrial truck for picking up a laterally disposed load from the ground or from racks comprises at least one chassis beam, which extends transversely to the longitudinal direction of the track, an extending and retracting drive for laterally moving a load carrier subassembly including load carrier arms. A lifting drive is provided for vertically moving the load carrier subassembly relative to at least chassis beam. The load carrier arms of the forked load carrier or corresponding roller-carrying arms, which are transversely movable, are provided with downwardly extensible load-supporting rollers, which are adapted to support the load during a transverse movement of the load carrier.
