P 2 1 Sany rotary drilling rig family 2 INNOVATION HISTORY OF SANY ROTARY DRILLING RIG First heavy power hydraulic rotary drilling rig, it broke 2003 the technology blockade of the developed country. Sany SR220C rotary drilling rig piled the first 2004 borehole at the construction of the National Stadium "Bird's Nest". In 2004 and 2005, Beijing Sany passed ISO 2005 9001 and CE certifications and became the first Chinese rotary drilling rig maufaturer to obtain such certifications. Beijing Sany became the biggest rotary drilling rig 2006 manufacturer and supplier in Asia. With Sany SR220R rotary drilling rig rolling off the 2007 production line, Beijing Sany became the first winch crowded rotary drilling rig manufacturer in China. SR360 was developed independently and Beijing 2008 Sany became one of the top level rotary drilling rig manufacturers around the world. The successful developing of SR 420 rotary 2009 drilling rig completely changed the pile foundation designing in China, and signified the rotary drilling rig manufacturing in China steps from “Made in China” to “Created in China”. Beijing Sany has developed and sold more than 1000 2010 units of rotary drilling rig, ranking the first in China again. And the record is being updated all the time. 3 Strong rock INNOVATION HISTORY OF SANY ROTARY DRILLING RIG drilling ability Automatic crowding control system Rotary drive multi-gear control High frequency pulse controlled crowding High working efficiency and energy-saving system helps to achieve high efficient Operator can choose drilling modes according drilling at rock layers. to the geological conditions, construction requirements and so on.

Working equipment adopts particular 5-level anti-shock technology, which increases the anti-shock capability by more 30%, and high strength steel increases mast strength by 30% to 40%. 4 High piling speed Main winch automatic releasing control Pulley yoke folding cylinder Automatic mast folding makes the mounting Improve construction efficiency: Releasing speed increases by 50%. and dismounting easy, time-saving and Main winch wire rope releasing adopts hydraulic laborsaving. confluence technology, which greatly increases the Modular designed pulley yoke with folding cylinder releasing speed and decrease ineffective working time. features lighter weight and higher strength. High/Low speed rotary drive crowding and hoisting Achieve fast rotary drive crowding and hoisting The hydraulic oil for rotary drive crowding and hoisting is supplied by exclusive pump and valves, which can easily achieve switching between high and low rotary drive hoisting speeds. High speed mode triples common hoisting speed, decreases ineffective working time.
