==Rescuing trapped miners==
In 2010, Schramm, Inc. assisted in the rescue of 33 miners trapped for 69 days as a result of the Copiapó mining accident in Chile. The company built both drilling rigs that were key in saving the miners. The Schramm T685 WS truck mounted drill bored a hole that, on 22 August 2010, was the first to break through to the 33 trapped men, confirming they had survived the accident.〔( Chesco company proud to help with Chilean miner rescue ), The Mercury, Pennsylvania (US), Brian McCullough, 14 October 2010〕 The company also manufactured the T130XD air core drilling rig owned by Geotec S.A., a Chilean-American joint venture drilling company. The T130 heavy drill was chosen by the general contractor for Plan B, Chilean firm Drillers Supply S.A., to widen one of the three wide and deep boreholes that were already used to keep the miners supplied using palomas. The T130 rig, in a three-way international race, was the first to open an escape shaft to the men.〔(Schramm Airdrill T130XD Rig Specifications PDF ), Schramm Inc.〕〔('Plan B' rises to the top for miners ), Houston Chronicle (US), Zain Shauk, 13 October 2010〕〔(Miners's Rescue In Chile: An Unprecendent Rescue Begins (Special Report)(English) ), The Santiago Times, Dominique Farrell and Dustin Zarnikow〕
