Abstract

A control mechanism for a refuse vehicle includes a first control valve that operates a first hydraulically controlled mechanism and a second control valve that operates a second hydraulically controlled mechanism. The control mechanism also includes a plurality of switches and a pneumatic control mechanism. The plurality of switches generates a valve select signal and a mode signal. The pneumatic control mechanism selectively controls the first control valve and the second control valve based on the valve select signal and the mode signal. An operator of the refuse vehicle actuates the plurality of switches while the operator is operating the pneumatic control mechanism.

First claim

What is claimed is:

1. A control mechanism for a refuse vehicle comprising:
a first control valve that operates a first lift controlled mechanism associated with the refuse vehicle;
a second control valve that operates a second lift controlled mechanism associated with the refuse vehicle;
a plurality of switches that generates a valve select signal and a mode signal;
a control mechanism that selectively controls the first control valve and the second control valve based on the valve select signal and the mode signal;
wherein the plurality of switches are actuated by the control mechanism; and
the plurality of switches generates a first valve control signal and a first mode signal when the plurality of switches are in a first position.

2. The control mechanism of claim 1 , wherein the control mechanism selectively controls the first control valve in a manual mode based on the first valve select signal and the first mode signal.

3. The control mechanism of claim 1 , wherein the plurality of switches generates a second valve control signal and a second mode signal when the plurality of switches are in a second position.

4. The control mechanism of claim 3 , wherein the control mechanism selectively controls the first control valve in an automatic mode based on the second valve select signal and the second mode signal.

5. The control mechanism of claim 1 , wherein the plurality of switches generates a third valve control signal and a third mode signal when the plurality of switches are in a third position.

6. The control mechanism of claim 5 , wherein the control mechanism selectively controls the second control valve in a manual mode based on the third valve select signal and the third mode signal.

7. The control mechanism of claim 1 wherein the plurality of switches are coupled to the control mechanism.

8. A method for operating a refuse vehicle comprising:
a first control valve for operating a lift arm assembly and a fork mechanism;
a second control valve for operating at least one loader arm coupled to a carry can loader;
generating a valve select signal and a mode signal;
selectively instructing the first control valve to lift, lower, move forward, or tilt the lift arm assembly or the fork mechanism based on the valve select signal and the mode signal; and
selectively instructing the second control valve to extend, retract, raise, lower, grab, or release the at least one loader arm based on the valve select signal and the mode signal.

9. The method of claim 8 further comprising generating a first valve control signal and a first mode signal and selectively controlling the first control valve in a manual mode based on the first valve select signal and the first mode signal.

10. The method of claim 8 further comprising generating a second valve control signal and a second mode signal.

11. The method of claim 10 further comprising selectively controlling the first control valve in an automatic mode based on the second valve select signal and the second mode signal.

12. The method of claim 8 further comprising generating a third valve control signal and a third mode signal.

13. The method of claim 8 further comprising selectively controlling the second control valve in a manual mode based on the third valve select signal and the third mode signal.
