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.

Claims13

Dependent claims

A refuse vehicle, comprising:

a container coupled to a chassis of the refuse vehicle;
a lift coupled to the container, the lift comprising an arm assembly configured to engage a refuse receptacle;
and
a control system configured to:
initiate a dump motion of the lift to dump refuse from the receptacle into the container;
determine a weight corresponding to the refuse in the receptacle;
determine a weight corresponding to the container;
and
in response to determining that the weight corresponding to the refuse in the receptacle together with the weight corresponding to the container exceeds a threshold value:
inhibit the dump motion of the lift beyond a predetermined position;
and
enable reversal of the dump motion from the predetermined position.
