Mexican contractor, CYUNSA Constructores y Urbanizadores del Noroeste S.A. de C.V., chose a High-Cap Multi Ripper bucket from Leading Edge Attachments to rip rock while cutting 84 miles of water pipeline through the Sonoran desert.
The High-Cap Multi Ripper is specially designed to focus six to nine times the force of a conventional excavator bucket on three ripper teeth positioned along a diagonal cutting edge for digging and ripping very hard material such as rock and caliche. CYUNSA Constructores has mounted it on a Hyundai 450-LC7 (100,000 lbs.) crawler excavator.
According to the contractor, the bucket "is doing a great job in digging and ripping rock for the 10-ft.-deep (3-meter) by 53-in.-wide (2-meter) trench." The 48- and 52-in.-diameter iron pipe they are installing is intended to conduct 628 gal. (2.378 cu. meters) of liquid per second. Installation is scheduled to be finished in May 2012.
CYUNSA Constructores y Urbanizadores del Noroeste S.A. de C.V. is based in Sonora. The company specializes in all facets of excavation work, including demolition, site development, septic systems, water pipelines and drainage.
