GQ-15 ENGINEERING DRILLING MACHINE
1. APPLICATIONS:
GQ-15 engineering drilling machine is newly designed special for large diameter pile hole drilling, can use forward-circulation and reverse circulation drilling methods mainly used in drilling large diameter pile for building, skyscraper, dam, harbor, bridge etc. and drilling large diameter well.
2. FEATURES:
? Big torque, lightweight and compact structure in compare with same kind machine.
? Mast, top-drive head move down or up along with, strength and rigidity.
? Top-drive head has large inner diameter (182×182mm).
? Reverse-circulation drilling if equipped with necessary equipment as well as forward-circulation drilling.
? Strength, five forward speeds and one reverse speed, suitable for drilling a variety of rock, easy to handle accidents happened in hole.
? Top-drive head is equipped with hand-powered chuck, square driving stem, large stroke, drilling efficiently.
? Hydraulic feed, big pull and push force easy to make pressure and depression drilling.
? Hydraulic retracting stroke is 1150mm, easy to lower and hoist drilling tools.
? Walking device, easy to move and find accurate hole position.
? Reasonable arrangement, easy to operate, smooth.
? Can be equipped with special derrick if user needs.
