FIG. 1 is a perspective view of the top, front and right side of the actuator for a lifting device showing my new design;
FIG. 2 is a front elevation view of the actuator;
FIG. 3 is a right side elevation view of the actuator;
FIG. 4 is a rear elevation view of the actuator;
FIG. 5 is a left side elevation view of the actuator;
FIG. 6 is a view looking upwardly at the actuator from below; and,
FIG. 7 is a top plan view of the actuator.
The broken-lines of FIGS. 1 through 7 depict assembly components as well as mounting hardware used to attach the actuator to other components of a lifting device. These broken line features are depicted for illustrative purposes only, and form no part of the claimed design.
