Abstract: A web roll handling and loading system and methods employ hubs positioned on opposing sides of a roll of web material wound on a hollow tubular core. Hub faces have an annular shape configured to be seated in respective ends of the hollow tubular core. The hubs are pivotably supported for pivoting between an operational position and a deflected position. The roll of web material is loaded on the hubs by lifting it from beneath the hubs to deflect the hub faces arcuately upward, then lowering the roll to allow the hub faces to pivot downward and become seated in the ends of the hollow tubular core. Alternatively, the roll is loaded into a pick-up tool by lowering the pick-up tool downward to the roll so the hubs deflect arcuately upward, then raising the tool so the hubs pivot downward and become seated in the hollow tubular core.

Each reel assembly further comprises a plurality of spokes separating a rim from a hub. Each hub provides a hub groove on each internal hub surface, and a hub aperture connecting each external hub surface with the hub groove. When the reel assemblies are received onto the axle, axle grooves on the axle align with the hub grooves to form a continuous ring aperture for each reel assembly. Separate axle apertures connect either one of the end faces of the axle with each axle groove, providing a separate passageway from each external hub surface to an axle end face. Hoses, electrical conduits, conductors or other similar carrier hardware deployed within hollow lances spooled on each reel assembly may connect to the hub apertures.
