A door latch activator system for a trailer or truck body coupled to a door latch, the system comprising:
- a plunger installed in a path of the door latch;
- a spring coupled to the plunger;
- a pneumatic valve configured to control flow of pressurized air;
- and
- a switch configurable into one of an open or closed position by the plunger, the switch configured to control flow of the pressurized air through the pneumatic valve depending on the position of the switch,
- wherein the plunger is moved toward the switch by a circular motion of the door latch to engage the switch and to activate the pneumatic valve to allow the pressurized air to flow through the pneumatic valve,
- wherein the plunger is moved away from the switch by the spring to deactivate the pneumatic valve to interrupt the pressurized air flowing through the pneumatic valve,
- wherein the flow of the pressurized air through the pneumatic valve is used to control synchronizing and managing units of the trailer or truck body.
