HPSi model 500 vibratory hammers and a custom-built, 60 to 80 foot extendible drill mast that BMC has mounted to Tutor’s Komatsu PC650 excavator.
After a comprehensive test comparing leading brands of foundation equipment, Tutor Saliba has taken delivery on two of our HPSi model 500 vibratory hammers and a custom-built, 60 to 80 foot extendible drill mast that BMC has mounted to Tutor’s Komatsu PC650 excavator.
The job entails driving 55 foot AZ-26 sheet piling in very difficult material. The Komatsu drill, which is capable of 50,000 ft. lbs. of torque, predrills the material and is followed by a crawler crane which drives the sheets to grade with the first model 500 vibro. A Komatsu PC1000 will then excavate down 35 feet where a tunnel will be constructed and later buried. A second crane will then use the other HPSi 500 to extract the sheet piling.
The job is scheduled for completion in the year 2002. When finished, it will bring Bay Area Rapid Transit (BART) trains directly to San Francisco’s international airport.
Bay Machinery thanks Ron Tutor and Chuck Scarrott of Tutor Saliba for their confidence in us and our equipment. We also thank the crew at HPSi abd BMC’s Fred Zatkoff for making it all happen.
