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 method of transporting a mobile aggregate plant comprising the steps of:
providing a first towing tractor attached to an end of a rock crusher section when said rock crusher section is coupled to a material feed section; charging a feeder air supply reservoir and a crusher section air supply reservoir from an air source on the first towing tractor; disconnecting an air supply line; a common airbag supply line and an electrical line between the material feed section and the rock crusher section; turning a rear axle brake valve to an “on” position; towing the rock crusher section forward, so as to cause a sliding out from under the material feed section, and terminating further relative translational motion; starting a material feeder section pump and unfold a material feeder trailer jack to a position; extending the material feeder trailer jack to lift the material feed section; disconnecting a brake air control line; towing the rock crusher section away from the material feed section; backing a second tow tractor under the material feed section; using the material feeder trailer jack to adjust a height characteristic of the material feed section to allow for an engagement between the second tow tractor and the material feed section; continuing backing the second tow tractor into the material feed section until a lock engages; retracting and folding the material feeder trailer jack and turning off the material feeder section pump; attaching the air supply line to the second tow tractor; and turning the rear axle brake valve to an “off” position.

2 . The method of claim 1 wherein said rock crusher section is rigidly coupled to the material feed section.

3 . The method of claim 2 wherein the air supply line is an independent height adjustable air supply line.

4 . The method of claim 3 wherein said an electrical line is a plurality of electrical lines.

5 . The method of claim 4 wherein said rear axle brake valve is a manual rear axle brake valve.

6 . The method of claim 5 wherein said step of towing the rock crusher section forward, so as to cause a sliding out from under the material feed section is done until contact with a slide stop is made which thereby prevents further relative translational motion.

7 . The method of claim 6 where said pump is a hydraulic pump.

8 . The method of claim 7 wherein said hydraulic pump is a gas-powered hydraulic pump.

9 . The method of claim 8 where the step of extending the material feeder trailer jack to lift the material feed section is done to lift the material feed section above the slide stop.

10 . The method of claim 9 wherein said lock is a king pin lock.

11 . The method of claim 10 wherein said king pin lock is a plurality of king pin locks.

12 . A method of transporting a rock crushing plant comprising the steps of:
providing a first towing tractor attached to a front end of rock crusher section when it is rigidly coupled to material feed section 110 ; charging both feeder air supply reservoir and crusher section air supply reservoir from an air source on the first towing tractor; disconnect both independent height adjustable air supply line and common airbag supply line and electrical lines between material feed section and rock crusher section; turn manual rear axle brake valve to an “on” position; tow rock crusher section forward, thereby sliding out from under material feed section until contact with a slide stop is made, thereby preventing further relative translational motion; start material feeder section gas-powered hydraulic pump and unfold material feeder trailer jack 210 to a vertical position; extend material feeder trailer jack 210 to lift material feed section 110 above the slide stop; disconnect brake air control lines; tow rock crusher section away from material feed section; back a second tow tractor under material feed section; use material feeder trailer jack to adjust height of material feed section to allow for engagement between second tow tractor and material feed section; continue backing second tow tractor into material feed section until king pin locks engage; hydraulically retract and fold material feeder trailer jack 210 and turn off material feeder section gas-powered hydraulic pump; attach independent height adjustable air supply line to second tow tractor; and turn manual rear axle brake valve to an “off” position.

13 . A method of transporting a mobile aggregate plant comprising the steps of:
providing a first towing tractor attached to an end of a first aggregate material processing section when said first aggregate material processing section is coupled to a second aggregate material processing section; charging a second section air supply reservoir and a first section air supply reservoir from an air source on the first towing tractor; disconnecting an air supply line; a common airbag supply line and an electrical line between the second aggregate material processing section and the first aggregate material processing section; turning a first axle brake valve to a position; towing the first aggregate material processing section forward, so as to cause a sliding out from under the second aggregate material processing section, and terminating further relative translational motion; starting a second section pump and unfolding a second section trailer jack to a position; extending the second section trailer jack to lift the second aggregate material processing section; disconnecting a brake air control line; towing the first aggregate material processing section away from the material feed section; backing a second tow tractor under the second aggregate material processing section; using the second section trailer jack to adjust a height characteristic of the second aggregate material processing section to allow for an engagement between the second tow tractor and the second aggregate material processing section; continuing backing the second tow tractor into the second aggregate material processing section until a lock engages; retracting and folding the second section trailer jack and turning off the second section pump; attaching the air supply line to the second tow tractor; and turning the first axle brake valve to a second position.

14 . The method of claim 13 wherein the first aggregate material processing section is a rock crushing section.

15 . The method of claim 13 wherein said second aggregate material processing section is a material feed section.

15 . The method of claim 13 wherein first axle brake valve is a rear axle brake valve.

16 . The method of claim 15 wherein said rear axle brake valve is a manual real axle brake valve.

17 . The method of claim 13 wherein said second section pump is a hydraulic pump.

18 . The method of claim 17 wherein said hydraulic pump is a gas-powered hydraulic pump.

19 . The method of claim 13 wherein said lock is a king pin lock.

20 . The method of claim 19 wherein said king pin lock is a plurality of king pin locks.
