Swivel wheel locking system and method thereof

A wheel locking system for selectively locking the movement of a swivel wheel, said system comprising:

• a wheel assembly comprising:
• a body portion comprising an engagement flange, wherein the engagement flange includes a flange wall and a flange aperture formed within the flange wall, and
• a wheel portion;
• a hydraulic actuator comprising a hydraulic cylinder, wherein the hydraulic cylinder configured to be fluidly connected to a wheel locking assembly valve, wherein the wheel locking assembly valve includes a at least one supply line and at least one return line, wherein hydraulic fluid from the at least one supply line is fluidly connected to a first point on the hydraulic cylinder and the at least one return line is fluidly coupled to a second point on the hydraulic cylinder;
• and
• a locking arm assembly coupled to an end of the hydraulic actuator, wherein the locking arm assembly comprises:
• a first locking arm having a first end and a second end, wherein the first locking arm is configured to be moved from a first position to a second position;
• a locking pin having a first end and a second end, wherein the locking pin comprises an exterior wall, an interior cavity at the first end, a locking pin channel formed between the first end and the second end of the locking pin, wherein the channel forms a passage from the exterior wall into the interior cavity of the locking pin, and an engagement member at the second end, wherein a first portion of the first locking arm resides within the interior cavity, wherein the locking pin is configured to slide along a linear path on the first locking arm;
• a biasing means positioned within the interior cavity between the first end of the first locking arm and an interior wall of the interior cavity, wherein the biasing means is configured to allow the locking pin to move along the linear path between an uncompressed position to a compressed position and maintain a pressure against the flange wall when the hydraulic actuator moves the first locking arm from a first position to a second position,
• wherein the wheel assembly is configured to rotate around an axis and the engagement member maintains contact with the flange wall until the wheel rotates into a position wherein the flange aperture is engaged by the engagement member.
