Abstract
A pneumatic excavator is configured to be pneumatically actuated using a safety mechanism, and includes a primary actuator; a secondary actuator fluidly coupled to the primary actuator; a flow valve fluidly coupled to the primary actuator; a shuttle valve fluidly coupled to the primary actuator, the secondary actuator and the flow valve; and a barrel coupled to an egress of the flow valve, the barrel defining an outlet of the pneumatic excavator. Actuating the primary and secondary actuators causes compressed air to be transmitted from the secondary actuator to the primary actuator and then to the flow valve to open the flow valve such that the compressed air exits through the outlet. Actuating one actuator and not the other causes the compressed air to be transmitted to the exit port of the shuttle valve and then to the flow valve to close the flow valve and prevent air flow therethrough.
