Abstract
A lift device comprises a mounting arm that includes a mounting member that is configured to be mounted to a structure. The lift device includes a vertical member having a lower end and an upper end spaced from the lower end along a first axis that is aligned with the vertical direction. A lifting boom includes a first end coupled to the upper end of the vertical member and the second end is configured to be secured to the object. The lift device includes a first actuation system disposed along the vertical member and configured to cause the lifting boom to rotate about the first axis. The lift device also includes a second actuation system configured to cause the lifting boom to rotate about a second axis that is perpendicular to the first axis.

A lift device configured to be mounted to a vehicle positioned on a surface and configured to carry an object from one location to another location relative to the vehicle, the lift device comprising:
- a mounting arm that includes a mounting member, the mounting member configured to be mounted to the rear of the vehicle;
- a vertical member that extends relative to the mounting arm along a vertical direction, the vertical member including a lower end, and an upper end spaced from the lower end along a first axis that is aligned with the vertical direction;
- a moveable lifting boom including a first end and a second end, the first end being coupled to the upper end of the vertical member, and the second end is configured to be secured to the object;
- a first actuation system disposed along the vertical member, the first actuation system configured to cause the lifting boom to rotate about the first axis;
- a second actuation system configured to cause the lifting boom to rotate about a second axis that is perpendicular to the first axis;
- and
- a flexible stability linkage connected to the second actuation system and the lifting boom, the flexible stability linkage configured to stabilize at least a portion of the second actuation system as the lifting boom rotates about the first axis and the second axis, wherein the flexible stability linkage is elongate along a linkage axis to define a length, the length of the flexible stability linkage does not increase as the lifting boom rotates about the first axis and the second axis.
