BIg Stan is a vehicle mounted drill rig built in 1986 by Anderson Drilling. The rig has been used on a number of construction projects in which conventional, smaller drilling rigs were unable to be used, particularly when projects call for drilling into hard soil. Notably, Big Stan was used in the construction of the First National Bank Tower in Omaha, the Benicia-Martinez bridge near San Francisco, and on expansions to the I-15/215 Beltway in Las Vegas. The drill rig was featured on Discovery Channel’s show “Monster Machines” in 2007.
Big Stan features a two piece design, significantly lowering the time and manpower needed to assemble it compared to contemporary rigs. The rig has been estimated as one of, if not the largest, vehicle mounted drilling rigs in the world.
History
Big Stan was built in 1986 by Anderson Drilling (Now part of Keller Group PLC) in Lakeside, California. The machine cost $1.5 million to construct and was named after the company president at the time, Stan Anderson, who was given a similar nickname due to his height of 6 ft 3 in.[1] The rig was originally built to meet the demand for a more powerful mobile drilling rig, specifically a demand for rigs capable of boring up to 260 feet (79 m) deep.[2] At the time, Big Stan was claimed to be the largest portable drill rig in the United States,[3] with some estimates placing it as the largest vehicle mounted drill rig in the world.[4]
From May to June 1999, Big Stan was used to drill the caissons for the First National Bank Tower in Omaha, Nebraska.[4] In 2004, while working on an expansion to the Benicia-Martinez bridge near San Francisco, "Big Stan" was filmed by Discovery Channel’s Canadian outlet for the show “Monster Machines”.[5] The episode aired in 2007.[6] In June 2007, Big Stan was used in the construction of the Pacific Street Bridge, in Oceanside, California. Big Stan was selected for its ability to achieve depths of 190 feet (58 m); conventional rigs were not capable of tunneling deep enough into the soft riverbed soil to earthquake proof the structure.[3] That same year, Big Stan was used for construction work on the Upper Northwest Interceptor sewage system. This project involved Big Stan drilling 41 vertical shafts, 15 feet (4.6 m) to 21 feet (6.4 m) in diameter, and 34 feet (10 m) to 70 feet (21 m) in depth. These tunnels were later finished by Vadnais Corp. who horizontally connected the segments by micro-tunnling.[7][8] In January 2009, Big Stan was taken to La Plata County, Colorado to drill at the Ridges Basin Dam. Here, it bored a 115 feet (35 m)-deep, 17 feet (5.2 m) diameter shaft as part of a larger project to build irrigation infrastructure to the surrounding homes.[6] That same year, Big Stan was taken to Snyder, Texas to work on the Snyder Wind Energy Project. Here, it was used to drill 40 feet (12 m) deep caissons into hard clay and sandstone.[9][10]
In August 2011, the drill rig was moved to Nevada to work on expansions to Interstate 15 in Las Vegas. The drill was contracted due to the lack of machines capable of breaking up the caliche-laden sedimentary rock present in the region. In addition, it was also used in the construction of the Blue Diamond Road flyover.[1] Later that month, Big Stan was used to drill the foundation for the Gold Line basket bridge in Los Angeles, California.[11] In 2015, Big Stan was used in the construction of the Yucca Loma Bridge in Apple Valley, California.[12]
Design
Big Stan weighs 125 tons, and is capable of exerting 534,000 ft-lbs of torque and 75,000 pounds (34,000 kg) of crowd pressure (the amount of force exerted over a meter[clarification needed][13]).[6][1] The drill is capable of boring down 200 feet (61 m) at 39 rpm with an auger weight of 15,000 pounds (6,800 kg). The drill can bore a hole up to 30 feet (9.1 m) in diameter and move dirt at a rate of 5 cubic yards per rotation. Big Stan is powered by a 600 horsepower, six-cylinder diesel engine made by Cummins.[1][2] When upright, the drill's boom[clarification needed] is 93 feet (28 m) in height.[6] The rig is normally mounted on a 40 feet (12 m) long, 5-axle truck but can uniquely be split into two pieces for transport.[1] When split apart one piece[clarification needed] was designed to travel on a 5-axle carrier, while the engine and upper tower were carried by a 7-axle tractor-trailer.[2] This is in contrast to other contemporary drill rigs, which required being dismantled into 8 to 10 pieces for transport. This design, along with built-in hydraulics[clarification needed] allowed a team of two people to assemble the rig in 30 minutes, compared to other contemporary rigs that required upwards of a week[clarification needed].[1][2]
