ABSTRACT:
An improved roller rung for a cable bed to reduce cable traction is disclosed. The roller rung comprises a holder rung having a groove, a plurality of roller drums and a plurality of partition panels. The partition panels are mounted in the groove from above or an end of the groove and securely engaged with the holder rung with panel engagement means. The roller drums turnably engage the partition panels and can rotate freely and independently on axial engagement means substantially above the groove or partially protruding from the groove. Cable weight is securely borne by the partition panels which are supported by the sturdy holder rung, thus the roller rung of the present invention can additionally provide an improved support of cable weight.
