  • Patent number: 10766696
    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 emptying 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.
    Type: Grant
