Description

Hydraulic Crawler Drills
Commonly used crawler equipment includes crawler drills,crawler hydraulic excavators,and crawler cranes etc
We are a professional hydraulic crawler drill manufacturer and supplier in China.Our SM-300 drill is a hydraulic rotary head rig mounted on crawler. This driling rig is used in a great variety of applications,not only suitable for tunneling,metro,and foundation engineering,such as anchoring drilling,micro piling,DTH,but also for geotechnical surveys drilling and mineral exploration drilling.
Features of Hydraulic Crawler Drills
-Top hydraulic head driver is driven by two high speed hydraulic motors,which can supply great torque and a wide range of the rotation speeds
-Feeding and the lifting system uses the hydraulic cylinders driving and chain transmission.So long feeding distance and convenient drilling are achieved.
-The V style orbit in the mast ensures the rigidity between the top hydraulic head and the mast, and helps maintain stablity at the high rotation speed
-Rod unscrew system helps simplify the operation.
-Hydraulic winch for lifting has better lifting stability and braking ability
-Rotation unit driving system is controlled by the variable flux pump
-As the steel crawler is driven by hydraulic motor,so a high level of maneuverability is accomplished
-The mast can turn360 in horizontal direction,90/-20 in vertical direction.The height can be adjusted at 2500mm. So our hydraulic crawler drilling rig can drill in all directions.
-The rig hydraulic system is controlled by proportion valve and circuit.
