A composite reeling device for winding up and letting out cables, steel ropes and cords includes a shaft, a sleeve, two outer wheel frames and a plurality of inner wheel frames. Two fixing end plates are disposed at two opposing ends of the shaft, respectively. The sleeve is fitted around the shaft. Fixing flanges are disposed at two opposing ends of the sleeve, respectively. The fixing flanges correspond in position to the fixing end plates, respectively. The outer wheel frames are disposed at the two ends of the sleeve, respectively, and removably coupled to the fixing flanges and the fixing end plates, respectively. The inner wheel frames each have a belt, a supporting ring and spokes. The spokes each have two ends connected to corresponding ones of the belts and the supporting rings. The belts are fitted around the sleeve.

The present disclosure relates to a cable reel comprising: a tubular main body extending along a longitudinal axis (L), comprising a plurality of tubular sections successively arranged side by side along the longitudinal axis (L) and releasably interconnected one to another; a first flange positioned at a first end of the main body, releasably connected to a first tubular section of the plurality of tubular sections; a second flange positioned at a second end of the main body, releasably connected to a last tubular section of the plurality of tubular sections, wherein each tubular section comprises at least two arcuate sections releasably interconnected in circumferential direction.

A locking system for a spool comprising a barrel, a flange, and a sliding lock. The sliding lock has at least one rail that slidably engages with at least one barrel detent and at least one flange detent to prevent rotation of the flange on the barrel. The sliding lock comprises at least one arm with at least one catch. The at least one catch can be removably locked into at least one recess on the flange.
