A locking mechanism (100) for heavy equipment having a first structure moveable relative to a second structure, the locking mechanism having an actuator mechanism (125), coupled to one of the first structure and the second structure, operable between a deployed position and a retracted position, a biasing member, a carriage member (110) operable between a restricted position, in response to the actuator (125) being in the retracted position, and an extended position. The biasing member (120) is configured to bias the carriage member toward the extended position in response to the actuator mechanism being in a deployed position and the carriage member is configured to prevent relative movement between the first structure and the second structure in the extended position.
