Abstract

Lifting devices for positioning a lift actuator in a high range position and a low range position are disclosed. The lifting devices may include a lift mast, a lift arm pivotally coupled to the lift mast, a lift actuator having a first end and a second end, and a linkage member having a first end and a second end. The first end of the lift actuator is pivotally coupled to the lift mast. The first end of the linkage member is pivotally coupled to the lift arm and the second end of the linkage member is pivotally coupled to the second end of the lift actuator such that the lift actuator includes a high range position relative to the lift arm and a low range position relative to the lift arm.
