- MGY-90L型立轴式岩芯钻机 钻机适用范围：
该液压钻机主要用于铁路、公路、水利、水电站滑坡治理工程及建筑基坑危岩锚固工程的锚固孔、排水孔、注浆孔施工，隧道管棚支护孔的施工。 Applications：The hydraulic drilling rig is mainly used in railway,highway,water conservancy,hydropower station,rocky landslide enof anchor holes,drain hole,grouting construction,tunnel pipe roof support hole construction.
- 本钻机结构紧凑，履带行走便于搬迁、就位；地盘、大臂、桅杆等处调幅机构均采用液压控制，可实现0.5～6米各种孔位的调节，操作方便且操作距离较远，安全性好。
- 本机采用国际著名品牌液压马达、液压泵，使整机性能稳定、可靠、寿命长。
- 本机适用范围广，钻进能力强；动力头行程长，钻进效率高。
- 动力头与导轨采用新型耐磨材料连接，导轨磨损很少。
- 本机在保证钻机刚性前提下，设计有2处旋转支撑，3处调幅机构，使钻孔可调角度范围大，定孔位更加方便。在履带固定不动的情况下，扇面钻孔可达-101.5°～+90°（基准水平为0°）；钻机在履带上回转角达到钻机-12°～+96°（钻机大臂与履带水平时为0°），侧向水平方向钻孔高度可达480mm～6300mm。
- 钻机设计有钻具摆放区，提高了钻机施工的适用性。
- 本钻机在较高孔位做强力给进操作时，速度要慢，绝对不允许给进冲击。以防止可能出现的钻机倾倒事故。
Features：- Compact structure,for this drill crawler walking is easy to move,in place;Chassis,the big arm,the place such as the mast amplitude modulation mechanism adopts hydraulic control,which can realize 0.5～6meters of hole position adjustment;convenient operation and opearting distance is far,good safety.
- The machine adopts the international famous brand hydraulic motot,hydraulic pump,making the whole machine performance is stable and reliable,long life.
- This machinge is used for a wide range,drilling ability;Power head long stroke,high drilling efficiency.
- Power head connected to the equipment with new wear-resisting material,the guide rail rail wear very little.
- The machine under the premise that ensure the drill rigid design with two rotational support,3 am,the large range of adjustable Angle drilling,hole location is more convenient.Under the condition of caterpillat stationary,sectoral dtilling can be up to 101.5°～+90°（baseline of 0°）;Drill rotary Angle on the track to drill -12°～+96°(big arm drill with track level of 0°),lateral horizontal direction drilling to heights of 480mm to 6300mm.
- With a drill rig design put area,improve the adaptability of drilling construction.
- The drill hole in high do strong feeding operation,slower,absolutely not allow fast feed.In order to prevent the rig dumping accidents that may occur.
