A hinge pin is suited for use in a hinge for a rotatable arm of a vehicle lift. The hinge pin has a groove formed within its side surface. The groove is configured to permit engagement of the pin with a restraining member configured to prevent rotation of the arm. The engagement of the pin with the restraining member limits longitudinal movement of the pin.

What is claimed is: 1. An automobile lift comprising: (a) a carriage having an arm mount, wherein the arm mount comprises a first arm mount flange extending from the carriage and a second arm mount flange extending from the carriage, wherein each of the first and second arm mount flanges has an aperture formed therethrough; (b) a rotatable arm having first and second spaced apart flanges for mounting the arm to the arm mount, wherein each of the first and second rotatable arm flanges has an aperture formed therethrough; (c) a hinge pin having a side surface, the hinge pin being configured to provide an axis of rotation for the rotatable arm, the rotatable arm being held to the arm mount by the hinge pin, the hinge pin having a groove formed in the side surface, wherein the hinge pin extends through the apertures of the first and second arm mount flanges and through the apertures of the first and second rotatable arm flanges; (d) a restraining member attached to said first rotatable arm flange, the restraining member being configured to engage the hinge pin adjacent the groove, wherein engagement of the hinge pin and the restraining member limits longitudinal movement of the hinge pin; and (e) a locking member, the locking member being configured to be selectively engaged with the restraining member, wherein rotation of the rotatable arm is prohibited when the locking member is engaged with the restraining member. 2. The automobile lift of claim 1, wherein the groove is fully annular. 3. The automobile lift of claim 1, wherein the hinge pin is configured to rotate with the rotatable arm. 4. The automobile lift of claim 1, wherein the hinge pin is prevented from rotating with the rotatable arm. 5. The automobile lift of claim 1, wherein the restraining member and the locking member each further comprise a set of splines, wherein said restraining member and said locking member are configured to engage with each other at respective said set of splines. 6. The automobile lift of claim 1, wherein the restraining member and locking member are in lateral engagement. 7. The automobile lift of claim 1, wherein the restraining member is secured directly to the first arm mount flange. 8. The automobile lift of claim 1, wherein the restraining member is attached to the first arm mount flange with one or more fasteners. 9. The automobile lift of claim 1, wherein the restraining member is fixedly secured to the hinge pin. 10. The automobile lift of claim 1, wherein the first arm mount flange and the second arm mount flange are fixed relative each other. 11. The automobile lift of claim 1, wherein a portion of the restraining member is substantially convex and a portion of the locking member is substantially concave. 12. The automobile lift of claim 11, wherein the convex portion of the restraining member is configured to engage with the concave portion of the locking member. 13. The automobile lift of claim 12, wherein each of the restraining member and the locking member comprise a plurality of complimentary splines. 14. The automobile lift of claim 1, wherein the locking member is associated with a locking pin, wherein selective displacement of the locking pin disengages the locking member from the restraining member to permit the rotatable arm to rotate. 15. The automobile lift of claim 14, wherein the locking pin is axially reciprocable to selectively cause disengagement of the locking member and the restraining member. 16. An automobile lift comprising: (a) a carriage having an arm mount, wherein the arm mount comprises a first arm mount flange extending from the carriage and a second arm mount flange extending from the carriage; (b) a rotatable arm having first and second spaced apart flanges for mounting the arm to the first and second arm mount flanges; (c) a hinge pin having a side surface, the hinge pin being configured to provide an axis of rotation for the rotatable arm, the hinge pin having a groove formed in the side surface, wherein the hinge pin secures the first and second rotatable arm flanges relative to the first and second arm mount flanges while permitting rotation of the rotatable arm relative to the arm mount; (d) a restraining member attached to said first rotatable arm flange, the restraining member being configured to engage the hinge pin adjacent the groove, wherein engagement of the hinge pin and the restraining member limits longitudinal movement of the hinge pin; and (e) a locking member, the locking member being configured to be selectively engaged with the restraining member, wherein rotation of the rotatable arm is prohibited when the locking member is engaged with the restraining member. 17. The automobile lift of claim 16, wherein the restraining member is secured to the first rotatable arm flange with one or more fasteners. 18. The automobile lift of claim 16, wherein the locking member is disposed on a locking pin, wherein the locking member is selectively engageable with the restraining member through longitudinal movement of the locking pin. 19. The automobile lift of claim 16, wherein the restraining member and the locking member each further comprise a set of splines, wherein the locking member is selectively engageable with the restraining member through engaging the splines of the locking member with the splines of the restraining member.
