Abstract
A slat replacement machine having an elongated rectangular frame supported at each end by a tracked drive unit which provides zero turn capability to the machine. A pair of outrigger assemblies is provided at the forward end of the frame and a pair of outrigger assemblies is provided at the rearward side of the frame. The outrigger assemblies may be pivotally moved from a stowed position adjacent the frame to an outwardly extending position. A telescopic boom is pivotally mounted on the upper end of a rotatable pedestal which extends upwardly from the center of the frame. Various components of the machine such as hydraulic cylinders and hydraulic motors are radio controlled.
Claims19
A machine for removing and installing concrete slats in a livestock building, comprising:
- an elongated, horizontally disposed frame having first and second ends and first and second sides;
- a first selectively reversible drive unit at said first end of said frame;
- a second selectively reversible drive unit at said second end of said frame;
- said first and second reversible drive units supporting said frame above a supporting surface;
- an upstanding pedestal rotatably mounted on said frame, about a vertical axis, between said first and second ends thereof;
- a boom arm assembly, having inner and outer ends, pivotally secured to said pedestal, about a horizontal axis;
- said outer end of said boom arm assembly adapted to support a slat therefrom;
- and a power source on said frame for powering at least some of said drive units, said pedestal and said boom arm assembly;
- a first elongated outrigger assembly having inner and outer ends;
- said inner end of said first outrigger assembly being pivotally secured, about a vertical axis, to said first side of said frame adjacent said first end of said frame;
- a second elongated outrigger assembly having inner and outer ends;
- said inner end of said second outrigger assembly being pivotally secured, about a vertical axis, to said first side of said frame adjacent said second end of said frame;
- a third elongated outrigger assembly having inner and outer ends;
- said inner end of said third outrigger assembly being pivotally secured, about a vertical axis, to said second side of said frame adjacent said first end of said frame;
- a fourth elongated outrigger assembly having inner and outer ends;
- said inner end of said fourth outrigger assembly being pivotally secured, about a vertical axis, to said second side of said frame adjacent said second end of said frame;
- each of said first, second, third and fourth outrigger assemblies being selectively pivotally movable with respect to said frame between operative and stowed positions;
- said first and second outrigger assemblies, when in their said stowed positions, being positioned closely adjacent said first side of said frame;
- said third and fourth outrigger assemblies, when in their said stowed positions, being positioned closely adjacent said second side of said frame;
- said outrigger assemblies, when in their said stowed positions, being substantially parallel to the longitudinal axis of said frame.
The machine of 1 wherein said boom arm assembly has a hoisting eye mounted thereon to enable the machine to be hoisted by another apparatus.
