Track system for mobile storage apparatus |
摘要 |
The invention provides longitudinally extending track support and track members for a mobile storage unit. The track support's upper surface has at least one protrusion which projects above and extends longitudinally along that upper surface. A mating recess extends within and along the track member's under surface. The recess and protrusion are sized and shaped for loose-fit longitudinal engagement of the protrusion within the recess when the track member is laid atop the track support. This permits limited transverse movement of the track member with respect to the track support, reducing susceptibility of the mobile storage unit's wheels to derailment if a transverse force is applied to mobile storage unit as it rolls along the track.
