Bridon will display a new dragline rope for the mining industry on Stand B1047 during AIMEX, September 6-9. The company says the Tiger Big T Bristar will deliver an overall cost reduction for users by providing a longer service life and, as a result, fewer change outs. A special feature of the rope is that its independent wire rope core is covered with a fluted polypropylene material with helical grooves around its outer surface. “This fluted shape core was formed by a special extrusion process,” said Bridon’s technical director, Johannes Verwaayen.

“The internal contour of the fluted profile matches the internal contours of the outer Dyform compacted strands, and the pitch of the helical grooves is controlled to closely match the lay of the rope.”

Six or eight compacted outer strands surrounded the independent wire rope core, giving it several competitive advantages, he said. “This includes achieving a higher metallic area and high breaking load due to compaction.

“With more accurate and durable placement of the outer strands, there is also even load distribution, reduced internal friction and increased bend fatigue,” Verwaayen said.

Bridon says The Tiger Big T, its latest innovation in drag and hoist ropes for draglines, is in keeping with the company’s philosophy of continuous product improvement and aim of being the technology leader for demanding rope applications.

Visitors to the company’s AIMEX stand will also be able to see other specialised wire ropes for the mining industry and can discuss technical issues with Bridon representatives.
