1. A track system configured for use with a storage rack assembly, the storage rack assembly having a frame assembly including first and second forward leg members, first and second rearward leg members and at least one shelf supported generally horizontally by the frame assembly, the track system comprising:
first and second forward wheel assemblies configured to be disposed on the respective first and second forward leg members;
first and second rearward wheel assemblies configured to be disposed on the respective first and second rearward leg members;
a forward axle assembly coupled between the first and second forward wheel assemblies in an operating position, the forward axle assembly comprising:
a first intermediate member that extends along an intermediate axis;
a first forward axle member that extends along a first forward axle axis, the first forward axle member having a first end coupled to the first forward wheel assembly and a second end slidably coupled to the first intermediate member;
a second forward axle member that extends along a second forward axle axis, the second forward axle member having a first end coupled to the second forward wheel assembly and a second end slidably coupled to the first intermediate member, wherein the first and second axle members are discontinuous and independently slidably coupled to the intermediate member at multiple axial locations providing an adjustable overall length of the forward axle assembly;
wherein in the operating position, the first intermediate member inhibits (i) rotation of the first forward axle member along the first forward axis and (ii) rotation of the second forward axle member along the second forward axis and maintains the first and second axle members in an orientation whereby the first and second axle axes are collinear with the intermediate axis facilitating parallel rolling of the first and second forward wheel assemblies during movement of the storage rack assembly from a storage position to an access position.
