Automated storage systems, and devices

A load handling device for lifting and moving storage containers stacked in a grid framework structure, the grid framework structure including a grid 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 having a grid pattern with a plurality of grid spaces, wherein the grid is supported by a set of uprights to form a plurality of vertical storage locations beneath the grid for containers to be stacked between and be guided by the uprights in a vertical direction through the plurality of grid spaces, wherein the load handling device comprises:

• a body mounted on a first set of wheels configured and arranged to engage with the first set of parallel tracks and a second set of wheels configured and arranged to engage with the second set of parallel tracks;
• wherein the first and second sets of wheels include wheels, at least one of the wheels having spokes, the spokes connecting a wheel rim to a wheel hub, and wherein the at least one wheel is at least partially resiliently deformable, wherein the wheel rim and wheel hub are made from a rigid material relative to the spoke material;
• and
• wherein the at least one 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.
