WHEELED CONCRETE SUPPLY HOSE MOVING DEVICE
A wheeled concrete hose moving or concrete placing device (10) that is movable over a support surface and that is operable to move a concrete supply hose at the support surface or place concrete at the support surface, said wheeled device comprising: a wheeled support (12), said wheeled support including a frame portion and wheels rotatably mounted at said frame portion; wherein said wheels of said wheeled support comprise a first set of wheels at one end of the wheeled support and a second set of wheels at the other end of the wheeled support; wherein said wheels are pivotable about respective vertical axes to steer said wheeled support over the support surface;wherein said wheels of said first set of wheels are pivoted together about the respective vertical axes and wherein said wheels of said second set of wheels are pivoted together about the respective vertical axes; wherein said wheels are selectively pivoted about the vertical axes to provide one of (i) a two wheel steering mode, (ii) a four wheel steering mode and (iii) a crab steering mode; and wherein, during steering of said wheeled support, said wheeled device limits pivoting of said wheels about their respective axes so that said wheels of said first set of wheels cannot pivot so as to be oriented perpendicular to said wheels of said second set of wheels.
