Scale Based Load Limiting For Refuse Vehicles
First Claim
1. A refuse vehicle comprising:
- a bin supported by the refuse vehicle;
a lift mechanism, the lift mechanism attaching to a container containing refuse to be added to the bin via a lift operation;
a sensor for sensing a weight, the weight varying in accordance with the refuse contained in the bin;
a controller, the controller receiving a weight signal from the sensor;
a lift lockout, the lift lockout inhibiting operation of the lift mechanism if the weight sensed by the sensor exceeds a predetermined value.

Abstract
A weight based load limiting system for a refuse vehicle. The system includes a weight determination module that generates a signal that varies in accordance with a vehicle weight. If the vehicle weight approaches or exceeds a predetermined maximum weight, the signal inhibits a portion of the loading or packing operation to prevent overloading the vehicle. In various configurations, the inhibiting can be to prevent a lifting of a refuse container to prevent empting the container into the vehicle hopper. In other various configurations, the inhibiting occurs by maintaining engine power to less than the engine power typically output during a packing operation.
