KG520/KG520H型露天潜孔钻车是应国家对柴油机排放要求进行升级的一款设备。配备有玉柴动力非道路四缸国三发动机，满足国家对排放和环保的要求。采用折边履带架和工程四轮一带，履带调平，柱塞行走马达，提高工作压力，增加其爬坡性能。增大停仰和举情油缸，满足其极限位置使用要求。增大回转扭矩和转速，采用推进马达和链条推进提升，提高提升力和可靠性。加大集尘器，提高吸尘效果。罩壳采用加厚型材折边，增加其强度和刚性。增加起吊吊环，方便装卸吊装。
The KG520/KG520H down the hole drill rig for open use is an improved device in compliance with national regulations on diesel-engineemissions. Equipped with the Yuchai four-cyinder engine (China l), the drll rig meets national standards for emissions and environmentThe folding frame track and four-wheel drive are adopted; and track leveling and the walking motor of plunger piston improve the workingpressure and climbing capacity. The expanded pitch and lifing-arm hydraulic cylinder enable it to meet the requirements of limitinapositon.The rotary torque and ravoling speed are rased: the propusion molor and chain are used to ra se the lming force and ralablityThe dust colector is enlarged to produce a better effect on dust coection.The thickened profle folderis used for the housing, thus improv.ing its level of intensity and rigidity;, and the additional ring makes handling and lifting convenient
KG520H型露天潜孔钻车增加集尘器，工作时更环保、可靠。The KG520H down-hole drll rig for open use is equipped with a dust collector, thus making operation more environment-friendly andreliable.
