1. A lift assembly on a ground surface, comprising:
(a) a lifting structure configured to actuate relative to the ground surface between a lowered position and a raised position;
(b) a lifting arm coupled with the lifting structure, where the lifting arm is configured to actuate with the lifting structure between the lowered position and the raised position;
(c) a yoke structure fixed to the lifting structure, wherein the yoke structure comprises:
(i) a rear side,
(ii) a vehicle-facing side, wherein the lifting arm extends away from the vehicle-facing side of the yoke structure, and
(iii) a tongue comprising a first surface and a second surface that cooperatively define at least a portion of an opening, wherein the first surface has a first surface area, and wherein the second surface has a second surface area that is less than the first surface area;
(d) a pin configured to couple the lifting arm with the yoke structure such that the lifting arm is configured to rotate relative to the yoke structure about a longitudinal axis of the pin, the pin comprising a complementary portion dimensioned to fit in the opening of the tongue; and
(e) an integrated anti-rotational assembly formed by the first surface of the tongue, the second surface of the tongue, and the complementary portion of the pin in the opening of the tongue, wherein the integrated anti-rotational assembly is configured to inhibit rotation of the pin relative to the yoke structure about the longitudinal axis of the pin,
wherein the first surface of the tongue defining a first part of the opening is located adjacent to the rear side of the yoke structure,
Wherein the second surface of the tongue defining a second part of the opening is located adjacent to the vehicle-facing side of the yoke structure.
