High efficiency YUCHAI YCR135 Rotary Drilling Rig
Description
Detailed description
Description
Powerful enough to drive hard rocks and deep piles
Rated torque of 135 kN · m (up to 145 kN · m), more than 50% higher than YCR90, easy to handle: moderately weathered rock, dense pebble layer, hard clay, deep hard soil.
Double motor high torque power head+high flow main pump, stable drilling, fast lifting, effortless deep pile driving, significantly leading in rock entry efficiency compared to small machines.
The most flexible and easy to transition among medium and large-sized machines
The whole machine weighs about 38-40 tons, much lighter than 180/200:
A regular trailer can be pulled without dismantling the mast, and there is no problem with transferring 1-2 times a day;
The construction site gate, municipal roads, and the surrounding area of the county are all easy to access, unlike the large machinery that selects sites.
Hydraulic telescopic track (2.8-3.6 m), capable of narrow road retraction and wide ground extension, with strong stability.
Solid structure and high pore quality
Strengthen the box type mast, large diameter slewing support, and heavy-duty chassis to resist torsion and shaking, and ensure the verticality of deep piles.
Parallelograms with variable amplitude and automatic leveling, fast and accurate hole alignment, reducing rework.
High end configuration, fuel-efficient and durable
Engine: Cummins QSL9 (162 kW/220 horsepower), National IV, with sufficient power, moderate fuel consumption, and easy starting at low temperatures.
Hydraulic: Kawasaki/Toshiba main pump+multi way valve, stable operation, low failure rate, and worry free long-term heavy work.
