Multi-stage modular road paving equipment and method of manufacture and sales
A multi-stage modular road building equipment system where a first stage base tractor is coupled to an intermediate stage, such as a spreading screw, and a third stage screed road paving tool attachment or other attachment such as a widener.
1. A multi-stage road paving equipment system comprising:
a base tractor first stage for providing basic controls and motive forces and a first stage-to-stage coupling, disposed at a rear end of said base tractor;
an intermediate stage, configured to mate with the first stage-to-stage coupling and further configured with a second stage-to-stage coupling, said intermediate stage being disposed rearward of said rear end of said base tractor and centered with respect to a center line extending rearward from said rear end of said base tractor;
the intermediate stage is additionally configured to laterally transport hot mix asphalt away from said center line;
wherein the intermediate stage is rigidly coupled to the base tractor first stage via the first stage-to-stage coupler which is configured not to be readily decoupled and recoupled in the field; and
a first of a plurality of third stage road paving tool attachments configured to mate with the second stage-to-stage coupling, where each of the plurality of third stage tool attachment provides a differing function and where each of the plurality of third stage road paving tool attachments is not configured to be directly mated to the first stage-to-stage coupling.
2. The system of claim 1 wherein the intermediate stage comprises a spreading screw for hot mix asphalt; and
the first of a plurality of third stage road paving tool attachments comprises a screed attachment.
3. The system of claim 1 wherein the first of a plurality of third stage road paving tool attachments comprises a road widener.
4. The system of claim 1 wherein the intermediate stage is coupled to the base tractor first stage via the first stage-to-stage coupler which consists of one of welding, bolts and rivets.
5. The system of claim 4 wherein the second stage-to-stage coupler is configured to be readily decoupled and recoupled in the field, with a blind mateable connection.
6. The system of claim 5 wherein the first of a plurality of third stage road paving tool attachments comprises a screed attachment.
7. The system of claim 5 wherein the first of a plurality of third stage road paving tool attachments comprises a road widener attachment.
8. A multi-stage road paving equipment system comprising:
a base tractor configured for providing control and motive force;
a first stage-to-stage coupling mounted on the base tractor;
an intermediate stage, configured to mate with the first stage-to-stage coupling;
a second stage-to-stage coupling, mounted on said intermediate stage;
the intermediate stage is additionally configured to laterally transport hot mix asphalt;
a plurality of third stage road paving tool attachments configured to mate with the second stage-to-stage coupling, where each of the plurality of third stage tool attachment provides a differing function and where each of the plurality of third stage road paving tool attachments is not configured to be directly mated to the first stage-to-stage coupling;
wherein the intermediate stage is rigidly coupled to the base tractor via the first stage-to-stage coupler which is configured not to be readily decoupled and recoupled in the field, and which consists of one of welding, bolts, and rivets;
wherein the second stage-to-stage coupler is configured to be readily decoupled and recoupled in the field and is blind mateable; and
wherein the intermediate stage comprises a spreading screw for distributing hot mix asphalt.
9. The system of claim 8 wherein a first of the plurality of third stage road paving tool attachments comprises a screed attachment.
10. The system of claim 9 wherein a second of the plurality of third stage road paving tool attachments comprises a road widener.
