Automatic door sequencing for discharging refuse from multi-compartment packer

A refuse truck body having a main compartment and at least one side compartment includes shields to close a rear opening of the compartments. A respective pushing device is provided for discharging refuse from each compartment. In a closed position, the shield is latched to the truck body by a locking device that selectively locks and unlocks each shield against its opening. A sequencing system is operatively connected between a lock for the packing unit and the actuator for closing and latching the shields, which prevents unlocking and raising the packing unit before the shields are closed and latched to the truck body. A sequencing system is operatively connected between the pushing device for a compartment and the actuator for closing and latching the shields, which prevents operation of the pushing device to discharge refuse from the compartment unless the shield for that compartment is unlatched.
