Abstract

A bifurcatable mobile rock crusher and method of transporting the same comprising providing a first segment which is separately towable on the highway and providing a second segment which is separately towable on the highway, where each segment is configured to be combined into one unit and towed as a unit on the highway.

First claim

We claim:

1. A system for sequentially transporting a rock crusher on a plurality of highways where each highway has differing regulations with respect to the transportation of trailers thereon, comprising:
a bifurcatable unified structure which, when in a unified configuration to perform aggregate material processing, is larger than is permissible to be legally towed on a first highway in a first state, and which unified structure is without a capability of substantial intermediate angular articulation between an aggregate processing apparatus and a material feed structure;
said aggregate processing apparatus being configured with a first plurality of wheels and a first tow end so as to be legally towable on said first highway, the aggregate processing apparatus being configured with an inlet opening for aggregate to be handled and a discharge opening for discharging processed aggregate;
said material feed structure with a second plurality of wheels and a second tow end, so as to be legally towable on said first highway;
a first truck configured to tow said aggregate processing apparatus on said first highway, from said first tow end in a first direction extending from said first plurality of wheels to said first tow end;
a second truck configured to tow said material feed structure on said first highway, from said second tow end in a second direction extending from said second plurality of wheels to said second tow end; and
where said unified structure, when in said unified configuration, can be operated for processing aggregate material without separating said aggregate processing apparatus and said material feed structure, and while maintaining said first direction and said second direction in a common direction.

2. The system of claim 1 wherein said aggregate processing apparatus further comprises a crusher pneumatic system thereon for providing a flexible support suspension with axle loading compensation.

3. The system of claim 2 wherein said material feed structure further comprises a material feed structure pneumatic system thereon which is configured for independent operation and control with respect to said crusher pneumatic system, and is further configured to be alternatively controlled by a unified controller, which is configured to simultaneously control portions of said crusher pneumatic system and said material feed structure pneumatic system when said aggregate processing apparatus and said material feed structure are mated into said unified structure.

4. The system of claim 3 wherein said aggregate processing apparatus is a road building material handling apparatus and further comprising a retractable stand coupled to one of the road building material handling apparatus and the material feed structure to provide support when not mated so as to form the unified structure.

5. The system of claim 1 wherein said unified structure consists of an identical number of towed wheels as in a sum of said first plurality of wheels and said second plurality of wheels.

6. The system of claim 5 wherein said unified structure consists of an identical number of axels as in a sum of first axels coupled to said first plurality of wheels and second axels coupled to said second plurality of wheels.

7. The system of claim 1 wherein said unified structure further comprises an air line link between a first otherwise independent air suspension system on the aggregate processing apparatus and a second otherwise independent air suspension system on the material feed structure so that a common air pressure is applied to all air suspension bags of the unified structure.

8. The system of claim 1 wherein said aggregate processing apparatus further comprises a crusher pneumatic system thereon for providing a flexible support suspension with axle loading compensation.

9. The system of claim 8 wherein said material feed structure further comprises a material feed structure pneumatic system thereon which is configured for independent operation and control with respect to said crusher pneumatic system, and is further configured to be alternatively controlled by a unified controller which is configured to simultaneously control portions of said crusher pneumatic system and said material feed structure pneumatic system when said aggregate processing apparatus and said material feed structure are mated into said unified structure.

10. The system of claim 9 wherein said aggregate processing apparatus is a road building material handling apparatus which further comprises a retractable stand.

11. A system for sequentially transporting a rock crusher on a plurality of highways where each highway has differing regulations with respect to the transportation of trailers thereon, comprising:
a bifurcatable unified structure, which when in a unified configuration to perform aggregate material processing, is larger than is permissible to be legally towed on a first highway in a first state and which unified structure is without a capability of substantial intermediate angular articulation between an aggregate processing apparatus and a material feed structure;
said aggregate processing apparatus being configured with a first plurality of wheels and a first tow end, so as to be legally towable on said first highway, the aggregate processing apparatus being configured with an inlet opening for aggregate to be handled and a discharge opening for discharging processed aggregate;
said material feed structure with a second plurality of wheels and a second tow end, so as to be legally towable on said first highway;
a first truck configured to tow said aggregate processing apparatus on said first highway, from said first tow end in a first direction extending from said first plurality of wheels to said first tow end;
a second truck configured to tow said material feed structure on said first highway, from said second tow end in a second direction extending from said second plurality of wheels to said second tow end;
where said unified structure, when in said unified configuration, can be operated for processing aggregate material without separating said aggregate processing apparatus and said material feed structure, and while maintaining said first direction and said second direction in a common direction;
wherein said aggregate processing apparatus further comprises a crusher pneumatic system thereon for providing a flexible support suspension with axle loading compensation;
wherein said material feed structure further comprises a material feed structure pneumatic system thereon which is configured for independent operation and control with respect to said crusher pneumatic system, and is further configured to be alternatively controlled by a unified controller, which is configured to simultaneously control portions of said crusher pneumatic system and said material feed structure pneumatic system when said aggregate processing apparatus and said material feed structure are mated into said unified structure;
wherein said aggregate processing apparatus is a road building material handling apparatus and further comprising a retractable stand coupled to one of the road building material handling apparatus and the material feed structure to provide support when not mated so as to form the unified structure;
wherein said unified structure consists of an identical number of towed wheels as in a sum of said first plurality of wheels and said second plurality of wheels;
wherein said unified structure consists of an identical number of axels as in a sum of first axels coupled to said first plurality of wheels and second axels coupled to said second plurality of wheels;
wherein said unified structure further comprises an air line li
