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.
Claims13
A control mechanism for a refuse vehicle comprising:
- a first control valve that operates a first implement associated with the refuse vehicle;
- a second control valve that operates a second implement associated with the refuse vehicle;
- a switch device that generates a valve select signal and a mode signal;
- a controller selectively controls the first control valve and the second control valve based on the valve select signal and the mode signal;
- wherein the switch device is actuated by the controller;
- and
- the switch device generates a first valve control signal and a first mode signal when the switch device is in a first position.
A method for operating a refuse vehicle comprising:
- a first control valve for operating a first implement associated with the refuse vehicle;
- a second control valve for operating a second implement associated with the refuse vehicle;
- generating a valve select signal and a mode signal;
- selectively instructing the first control valve to lift, lower, move forward, or tilt the first implement 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 second implement based on the valve select signal and the mode signal.
