First Claim
Patent Images
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;
an intermediate stage, configured to mate with the first stage-to-stage coupling and further configured with a second stage-to-stage coupling;
the intermediate stage is additionally configured to transport hot mix asphalt beyond merely providing a second stage-to-stage coupling;
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.

12. A method of fulfilling customer orders for a variety of road paving equipment comprising the steps of:
-
manufacturing and storing in inventory a base road paving tractor which is configured to provide controls and motive forces;
the tractor configured with a first stage-to-stage coupler;
manufacturing and storing in inventory an intermediate stage member which is configured to mate with the first stage-to-stage coupler where the intermediate stage is configured to provide functionality beyond merely coupling between the base road paving tractor and a tool attachment;
manufacturing and storing in inventory a plurality of differently functioning road paving tool attachments, each of which is configured for coupling via a second stage-to-stage coupler to the intermediate stage member;
receiving a request for a first predetermined model of road building equipment;
assembling a unit of the first predetermined model of road building equipment using, from an inventory, the first stage base tractor, the intermediate stage member and a first of the plurality of differently functioning road paving tool attachments, where attachment between the first stage base tractor and the intermediate stage member is configured so as not to be readily detachable and re-attachable in the field; and
replenishing an inventory with items which were used to assemble the unit of the first predetermined model of road building equipment;
receiving a request for a second predetermined model of road building equipment which performs a different function than the first predetermined model of road building equipment;
assembling a unit of the second predetermined model of road building equipment using, from an inventory, the first stage base tractor, the intermediate stage member and a second of the plurality of differently functioning road paving tool attachments, where attachment between the first stage base tractor and the intermediate stage member is configured so as not to be readily detachable and re-attachable in the field; and
replenishing an inventory with items which were used to assemble the unit of the second predetermined model of road building equipment.
