Abstract

In accordance with example embodiments, a system may include a first feeder configured to transport asphalt, a second feeder configured to receive the asphalt from the first feeder, and a controller configured to control a speed of the first feeder and the second feeder in response to an input from an operator.

Claims

1. A system comprising:

a first feeder configured to transport asphalt;

a second feeder configured to receive the asphalt from the first feeder; and

a controller configured to control a speed of the first feeder and the second feeder in response to at least one of an input from an operator and a sensor.

2. The system of claim 1, wherein

the first feeder includes a first motor and the second feeder includes a second motor and the controller is configured to control the first and second motors.

3. The system of claim 2, wherein the first motor is a hydraulic motor and the second motor is a hydraulic motor.

4. The system of claim 3, wherein the first motor is controlled by first hydrostatic pump and the second motor is controlled by a second hydrostatic pump and the controller controls the first and second hydrostatic pumps to control the first and second hydraulic motors.

5. The system of claim 1, wherein the controller is configured to substantially simultaneously increase and decrease speeds of the first and second feeders based on the input from the operator.

6. The system of claim 1, further comprising:

a third feeder configured to receive the asphalt from the second feeder, wherein the controller is further configured to control a speed of the third feeder in response to the input from the operator.

7. The system of claim 1, further comprising:

a third feeder configured to provide the asphalt to the second feeder, wherein the third feeder is controlled independently of the first and second feeders.

8. The system of claim 1, further comprising:

a first load sensor configured to measure a first load associated with the first feeder; and

a second load sensor configured to measure a second load associated with the second feeder, wherein the controller is further configured to control a speed of the first and second feeders based on at least one of the first and second loads.

9. The system of claim 8, wherein the first feeder includes a first motor and the second feeder includes a second motor and the first load is a first pressure and the second load is a second pressure.

10. The system of claim 9, wherein the first and second motors are hydraulic motors.

11. A method comprising:

moving asphalt with a first feeder;

moving the asphalt with a second feeder, the second feeder receiving the asphalt from the first feeder; and

controlling speeds of the first feeder and the second feeder by inputting an input to a controller.

12. The method of claim 11, wherein

the first feeder includes a first motor and the second feeder includes a second motor and controlling speeds of the first and second feeders includes controlling speeds of the first and second motors.

13. The method of claim 12, wherein the first motor is a hydraulic motor and the second motor is a hydraulic motor.

14. The method of claim 13, wherein the first motor is controlled by first hydrostatic pump and the second motor is controlled by a second hydrostatic pump and controlling speeds of the first and second motors includes controlling speeds of the first and second hydrostatic pumps.

15. The method of claim 11, wherein controlling speeds of the first and second feeders includes one of substantially simultaneously increasing and decreasing speeds of the first and second feeders.

16. The method of claim 11, further comprising:

moving the asphalt with a third feeder, wherein the controller is further configured to control a speed of the third feeder in response to the input from the operator.

17. The system of claim 11, further comprising:

moving the asphalt via a third feeder to the second feeder, wherein the third feeder is controlled independently of the first and second feeders.

18. The method of claim 11, further comprising:

controlling speeds of the first and second feeders based on at least one of a first load sensed by a sensor configured to measure a load associated with the first feeder and a second load sensor configured to measure a load associated with the second feeder.

19. The method of claim 11, wherein the first feeder includes a first motor and the second feeder includes a second motor and the first load is a first pressure and the second load is a second pressure.

20. The system of claim 19, wherein the first and second motors are hydraulic motors.
