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.
◆ Big torque, lightweight and compact structure in compare with
same kind machine.
◆ Mast, top-drive head move down or up along with, strength and
◆ 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
◆ 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
◆ Hydraulic retracting stroke is 1150mm, easy to lower and hoist
◆ 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.
