Crane Mounted CFA - Single Stroke

Video Transcription

Video Summary

David Zanchetta of Birmingham Foundation Equipment explains how the company selects crane-and-lead systems for foundation work beyond the reach of conventional rigs. His British Columbia case study involved installing 750 mm CFA piles to 48 metres for a high-rise development. A traditional drill rig could not complete the piles in one stroke, and repeatedly adding auger sections would disrupt concrete placement and reduce productivity.<br /><br />The team considered Birmingham’s H25, H28 and H36 spud leads. The H25 was too short and lacked torque; the H28 could have worked, but the contractor already had H36 leads available. Crane selection required checking both operating stability and the ability to raise the long system into position. A 250-ton crane offered too little working range, while the locally available LR 1300 provided ample capacity. Because the complete system was too heavy to lift at once, crews raised it in sections.<br /><br />The presentation emphasizes choosing equipment based on project needs, local availability, cost and safe setup—not simply matching a lead to a crane.
