Wheel

A wheel for MHE (material handling equipment), the wheel comprising:

• a hub;
• a rim;
• and
• spokes, wherein the spokes supportively connect the rim to the hub, wherein the spokes are arranged in a spoke network and least some of the spokes are non-radial, and wherein at least a portion of the spokes are made from a compliant material relative to a material of the rim and or the hub, and wherein the wheel includes two or more layers, wherein the two or more layers include a first-type layer that is layered with at least one second-type layer having curved spokes.

Method for moving a system containing at least one wheel, or a number of wheels as a set, wherein the at least one wheel includes:

• a hub;
• a rim;
• and
• spokes, wherein the spokes supportively connect the rim to the hub, wherein the spokes are arranged in a spoke network and least some of the spokes are non-radial, and wherein at least a portion of the spokes are made from a compliant material relative to a material of the rim and or the hub, and wherein the wheel includes two or more layers, wherein the two or more layers include a first-type layer that is layered with at least one second-type layer having curved spokes, wherein the method comprises:
• operating a set of driven wheels on a load handling device, wherein the load handling device is operable on a grid framework storage system structure having a first set of parallel rails or tracks and a second set of parallel rails or tracks extending substantially perpendicularly to the first set of rails or tracks in a substantially horizontal plane to form a grid pattern having a plurality of grid spaces;
• or
• operating a set of wheels on a flow racking system, wherein the set of wheels is attached to a tray or tote;
• or
• operating a set of wheels on a flow racking system, wherein the set of wheels are used as rollers in a track;
• or
• operating a set of wheels in a caterpillar track.
