KG520/KG520H Down The Hole Drill Rig For Open Use

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 KG520/KG520H down the hole drill rig for open use is an improved device in compliance with national regulations on diesel-engine emissions. Equipped with the Yuchai four-cylinder engine (China III)，the drill rig meets national standards for emissions and environment.The folding frame track and four-wheel drive are adopted; and track leveling and the walking motor of plunger piston improve the working pressure and climbing capacity. The expanded pitch and lifting-arm hydraulic cylinder enable it to meet the requirements of limiting position. The rotary torque and revolving speed are raised; the propulsion motor and chain are used to raise the lifting force and reliability.The dust collector is enlarged to produce a better effect on dust collection. The thickened profile folder is used for the housing, thus improving its level of intensity and rigidity; and the additional ring makes handling and lifting convenient.
