According to fact that total wire area of 29F strand and 36WS strand is very close,combined with relevant expla-nations in GB/T 8706-2017,it is further confirmed that 6 × 29F construction wire rope and 6 × 36WS construction wire rope are similar mechanical and physical properties wire rope.Based on GB/T 5972-2016,minimum visible broken wire count for reaching discard condition under the same usage conditions for two construction wire ropes is not the same,which suggests that safety properties of the same construction category but different specific construction wire ropes may not be consistent.It is analyzed that properties difference between different construction wire ropes affecting their actual service life under complex operating conditions.
