Railgear assembly with a single-action activation & locking mechanism

A method, comprising:

• providing fluid to a manifold in response to a user input;generating a pressure with the fluid within the manifold;
• transitioning, by the pressure, a locking assembly from a first locked position to an unlocked position when the pressure is less than a determined threshold wherein the locking assembly is configured to prevent a railgear assembly from transitioning between a road configuration and a rail configuration in the first locked position, and wherein the locking assembly is configured to allow the railgear assembly to transition between the road configuration and the rail configuration in the unlocked position;
• transitioning, by the pressure, the railgear assembly between the road configuration and the rail configuration when the pressure is greater than or equal to the determined threshold;
• and transitioning the locking assembly of a railgear from the unlocked position to a second locked position in response to the railgear assembly having transitioned between the road configuration and the rail configuration.

A fluid powered assembly, comprising:

• a fluid powered actuator configured to transition a railgear assembly between a road configuration and a rail configuration;
• a locking assembly configured to transition between a first locked position and an unlocked position, wherein the locking assembly is configured to prevent the railgear assembly from transitioning between the road configuration and the rail configuration in the first locked position, and wherein the locking assembly is configured to allow the railgear assembly to transition between the road configuration and the rail configuration in the unlocked position;
• and
• a manifold configured to receive fluid from a pump in response to a user input, wherein the fluid is configured to generate a pressure within the manifold, wherein the manifold comprises a valve configured to transition from an open position to a closed position when the pressure meets or exceeds a determined threshold, wherein the manifold is configured to provide the fluid to the locking assembly when the valve is in the open position, causing the locking assembly to transition from the first locked position to the unlocked position, and wherein the manifold is configured to provide the fluid to the fluid powered actuator when the valve is in the closed position, causing the fluid powered actuator to transition the railgear assembly between the road configuration and the rail configuration.
