Apparatus for moving concrete pump hoses
DCFirst Claim
1. A mobile apparatus for supporting a concrete hose from a concrete pump comprising:
- a frame supported for movement over a surface by a front pair of wheels and a rear pair of wheels;
a steering mechanism associated with each said front and rear pairs of wheels, each wheel being pivotally supported for movement about a generally vertical axis, said steering mechanism being operable to pivot each said wheel in said pair of wheels about the corresponding said generally vertical axis through an arcuate angle of at least 90 degrees so that each said wheel is positionable in a longitudinally extending orientation and in a transversely extending orientation, said front pair of wheels being pivotally positionable independently of said rear pair of wheels; and
an attachment apparatus for selectively supporting said concrete hose, said attachment apparatus including a front horn member and a rear horn member positionable to support said concrete hose when placed into engagement therewith.

Abstract
A mobile apparatus moves a concrete pump hose over a base surface and has a wheeled frame in which the wheels are pivotable about a generally vertical pivot axis between a longitudinal orientation and a transverse orientation. Each of the front pair of wheels and the rear pair of wheels are coupled to a steering mechanism to permit independent pivotal movement of the respective pairs of wheels to provide four wheel steer of the frame. The hose is supported by front and rear horn members above the base surface and below the frame. An intermediate grappling apparatus engages the hose to affect elevation thereof onto the horn members. The horn members are split between a fixed portion and a pivotally movable portion that pivots away from the fixed portion to permit the hose to be elevated above the horn members. A boom apparatus can substitute for the grappling apparatus.

8. A mobile apparatus for supporting a concrete pump hose comprising:
-
a frame adapted for movement over a base surface and including a front pair of ground engaging members and a rear pair of ground engaging members supporting said frame for movement over the base surface, said frame being elevated above said base surface by said ground engaging members; and a front horn member and a rear horn member mounted on said frame to support said concrete pump hose beneath said frame between said ground engaging members; and a grappling apparatus mounted on said frame in a central position between said front and rear horn members to secure and elevate said concrete pump hose from said base surface onto said front and rear horn members. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. In a mobile apparatus for supporting a concrete pump hose having a frame adapted for movement over a base surface by a front pair of wheels and a rear pair of wheels, said frame being steerable over said base surface to position said concrete pump hose as desired, the improvement comprising:
-
a rear horn member located between said rear pair of wheels, said rear horn member being operable to support said concrete pump hose in an elevated position above said base surface and below said frame so as to carry said concrete pump hose beneath said frame between the respective wheels of at least one of said pairs of wheels, said rear horn member including a fixed portion and a movable portion operable to move away from said fixed portion to permit an elevation of said concrete pump hose above said horn member so as to be supported thereon; and a boom apparatus supported on said frame and including a boom member extending above said frame and being pivotally movable about a generally vertical pivot axis to direct concrete therethrough to a location remote from said frame, said boom apparatus further including a conduit having a vertical portion aligned with said vertical pivot axis to allow a flow of concrete from said concrete pump hose beneath said frame to said boom member extending above said frame. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
