1. A hydraulic cylinder assembly, disassembly and maintenance system, comprising:
a cylindrical pipe having first and second ends and resting on an integrated foot and crane mount, the cylindrical pipe including:
a pair of parallel guide rails fixed along a top portion thereof; and
a pair of ball screws disposed in parallel between the pair of guide rails extending along a length of the cylindrical pipe, each ball screw including a sprocket attached to one end thereof at the first end of the cylindrical pipe;
an overhead crane assembly including at least one support beam extending from the integrated foot and crane mount and supporting an overhead crane at a position above and extending along the length of the cylindrical pipe, the overhead crane including at least two rolling hoists that roll along the overhead crane to hoist and move a hydraulic cylinder over the cylindrical pipe;
a torque head assembly including:
a pair of rail guides fixed to a bottom thereof to lock onto and slide along the pair of guide rails;
a ball screw push bar disposed between the pair of rail guides, the ball screw push bar including a pair of ball screw nuts each to threadingly receive a corresponding ball screw therethrough to move the torque head assembly along the guide rails when the ball screws are rotated;
a rotating reel having notches around a circumferential surface thereof and an axis of rotation in parallel with the cylindrical pipe and a torque head tooling connector plate connected thereto and configured to rotate along with the rotating reel and to receive a first tooling piece thereon to securely engage with a first end of a hydraulic cylinder to rotate the first end of the hydraulic cylinder;
a torque head hydraulic motor configured to rotate the rotating reel at a high speed and low torque; and
a high torque cylinder configured to extend and retract to rotate the rotating wheel at a lower speed and higher torque than the torque head hydraulic motor; and
a tail stock assembly including:
a tail stock tooling connector plate having a pair of slide plates to slide along the guide rails and configured to receive a second tooling piece thereon to securely engage with a second end of the hydraulic cylinder in a non-rotating manner while the torque head tool connector plate and first tooling piece rotate the first end of the hydraulic cylinder.
