CABLE
2.3.1
Installation Requirements for Cable
Cable used for preassembled mattresses shall be sufficiently sized and
fastened for the size/weight of the assembled mattresses such that the
assembled mattresses can be placed in compliance with OSHA standards. The
manufacturer shall be responsible for determining the minimum cable
strength compatible with the mattress size for safe handling. Cable
strength shall be based on a minimum factor of safety of 5, and include
appropriate reduction factors for mechanically crimped cable, and other
fasteners. If applicable, loading conditions shall include the use of a
spreader bar for placing the mattresses.
2.3.2
Fasteners Other than Cable
Any systems which rely on geotextiles (or other fabric integral with the
mattress) to maintain block-to-block interconnection shall meet the
applicable portions of this specification for cables. Geosynthetics
