1. A lifting device comprising:
a lift mast;
a lift arm pivotally coupled to the lift mast, the lift arm having a first end and a second end opposite the first end;
a lift actuator having a first end and a second end, the first end of the lift actuator pivotally coupled to the lift mast;
a linkage member having a first end and a second end, the first end of the linkage member pivotally coupled to the lift arm and the second end of the linkage member pivotally coupled to the second end of the lift actuator such that the lift actuator is positionable between a high range position relative to the lift arm and a low range position relative to the lift arm; and
a pair of spaced apart stabilizers extending from the lift arm for preventing lateral separation of the linkage member from the lift arm, a first stabilizer of the pair of spaced apart stabilizers located a first distance from the first end of the lift arm, a second stabilizer of the pair of spaced apart stabilizers located a second distance from the first end of the lift arm greater than the first distance,
wherein the lift actuator is selectively positionable in the high range position and the low range position.
