Nested lift-and-steer support wheels

A material handling device, comprising:

• a driven end and a lifting end;
• a pair of housings disposed on the lifting end that are connected to and extending from the driven end;
• a first linkage and a second linkage that extend from the lifting end and are configured to respectively translate along a longitudinal axis of each respective housing;
• at least one actuator configured to drive the first linkage and the second linkage, wherein a first end of the at least one actuator is coupled to a portion of the driven end, and a second end of the at least one actuator is operably coupled to the first and second linkage, wherein the at least one actuator is configured to translate the first linkage and the second linkage along the longitudinal axis of each respective housing;
• and
• at least one cantilever wheel configured to adjust an angle of the driven end and the lifting end of the material handling device, the at least one cantilever wheel comprising a mount positioned within the driven end, the mount having a first end coupled to the at least one cantilever wheel and a second end coupled to another actuator via a third linkage,
• wherein the other actuator is configured to extend the third linkage towards the lifting end, such that the mount rotates the at least one cantilever wheel from a first state to a second state, such that the driven end is positioned at a first angle, and
• wherein the other actuator is configured to retract the third linkage away from the lifting end, such that the mount rotates the at least one cantilever wheel from the second state to the first state, such that the driven end is positioned at a second angle.

A material handling device:

• a driven end and a lifting end;
• a pair of housings disposed on the lifting end that are connected to and extending from the driven end;
• a first linkage and a second linkage respectively disposed in each of the housings;
• and
• at least one actuator configured to drive the first linkage and the second linkage along a longitudinal axis of each respective housing,
• wherein a first end of the at least one actuator is coupled to a portion of the driven end,
• wherein a second end of the at least one actuator is coupled to the first linkage and the second linkage,
• wherein each housing comprises a rotational assembly mounted therein and coupled to a respective one of the first linkage and the second linkage, and
• wherein the rotational assembly is configured to transition at least one wheel from a first position being located within the housing to a second position being located outside of the housing to a third position in which a heading of the at least one wheel is oriented.
