Automatic door sequencing for discharging refuse from multi-compartment packer

A method of operating a multi-compartment rear load refuse packer including truck body defining a main compartment and at least one side compartment, with each compartment having a rear opening extending from a roof edge to a floor edge at a rear of the truck body, a packing unit pivotally connected to the truck body, a respective pushing device for discharging refuse from the compartment, and a congruent elongated shield for the opening of each side compartment, wherein the method comprises:

• with the packing unit in a packing position, configuring the shield in a fixed position whereby an operator deposits refuse in the packing unit and the packing unit packs the deposited refuse under the shield and into the compartment;
• with the packing unit in an unloading position pivoted away from the compartments and the shields moved, via a power source, to an open position relative to the compartments, a pushing device within the body discharges compacted refuse out of the compartments;
• in dependence on a sequencing logic system connected between the pushing device and the packing unit, actuating operation of the pushing device only if the packing unit is in the unloading position.
