Metal composite cable carrier

In a carrier for supporting energy transmission lines having at least two parallel articulated chains joined laterally to have coaxial pivot axes, each chain being made of inner links pivotally connected end to end to outer links, each outer link including a first half and a second half, each inner link having at least one end being sandwiched between ends of said first and second outer link halves which are pivotally connected to said end of said inner link, the improvement wherein said first and second outer link halves are joined together by a retainer clip, said first and second outer link halves have a cored center and wherein said retainer clip is snapped over arms defined by said cored center.

In a carrier for supporting energy transmission lines having at least two parallel articulated chains joined laterally to have coaxial pivot axes, each chain being made of inner links pivotally connected end to end to outer links, each outer link including a first half and a second half, each inner link having at least one end being sandwiched between ends of said first and second outer link halves which are pivotally connected to said end of said inner link, the improvement wherein said first and second outer link halves are joined together by a retainer clip wherein each said outer link includes two integral pivot posts, one at each end thereof coaxial with the pivot axis at said end, each said pivot post extending into a coaxial hole formed in the adjacent inner link.

In a carrier for supporting energy transmission lines having at least two parallel articulated chains joined laterally to have coaxial pivot axes, each chain being made of inner links pivotally connected end to end to metallic outer links, each outer link including a first half and a second half, each inner link having at least one end being sandwiched between ends of said first and second outer link halves which are pivotally connected to said end of said inner link, said outer link halves having posts which extend into openings in said sandwiched ends of said inner links from opposite sides of said inner links, the improvement wherein at least one of said posts is integral with one of said outer link halves and has a side surface which is sheared out of and integral with said link and which intersects an inner surface of said one of said outer link halves in a sharp 90° substantially zero radius inside corner.
