KG590/KG590H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。增大俯仰和举臂油缸，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 KG590/KG590H down the hole drill rig for open use is an improved device in compliance with national regulations on diesel-engineemissions. Equipped with the Yucha four-cylinder encine (China l), the drll rig meels 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 limitingposition. The rotary torque and revolving speed are raised: the propusion motor and chain are used to raise the lifina force and reliabilityThe dust colector is enlarged to produce a better efect on dust colection. The thickened profle folder is used for the housing, thusimproving its level of intensity and rigidity; and the additional ring makes handling and lifting convenient.
KG590H型露天潜孔钻车增加集尘器，工作时更环保、可靠。The KG590H down-hole drill rig far open use is equipped with a dust collector, thus making operation more environment-friendly andreliable.
