KG open-air DTH drill rig
KG550型露天潜孔钻车

introduction and Parameter:

Here is the English translation of the paragraph:

Equipped with a Yuchai four-cylinder engine and an integrated controller, it monitors the drill rig's operating parameters in real time. It adopts folded track frames and heavy-duty undercarriage components, with track leveling and reinforced piston travel motors to increase working pressure and enhance climbing ability. The slide plate retaining strips are made of wear-resistant material to ensure a long service life for the feed beam. The dual-motor rotator with a large reduction ratio provides the drill rig with a rotation torque of over 4000 Nm, and the feed motor combined with 24A roller chain feed greatly improves drilling operation reliability. A high-pressure-resistant, large-displacement cast iron gear pump is used to ensure product quality, while offering the advantages of long service life and stable performance. The layout of the frame components is optimized, significantly increasing internal space. The cover shell uses thickened sections with multiple side-opening doors for easy maintenance. This machine can be widely used for drilling blast holes in construction sites such as large-diameter photovoltaic pile foundations, hydropower projects, open-pit mining, road construction, and tunnel construction.
