Description
Detailed description
Description
Double the power and be able to perform harder tasks
90 kN · m torque, more than twice that of YCR40, easy to dry: strongly weathered rock, pebble layer, dense sandy soil, medium hardness clay.
Dual motor power head+high flow main pump, fast drilling and efficient lifting, significantly higher efficiency in batch building and municipal pile construction.
Not too big or too small, still convenient for transition
The whole machine weighs about 22-24 tons and belongs to the category of “medium and small rotary excavator”:
Can enter residential areas, construction sites, and rural roads;
A single trailer can pull it without dismantling the mast, and there is no problem transferring twice a day.
Cheaper, fuel-efficient, and cost-effective compared to large machines (120, 160), suitable for small and medium-sized engineering teams.
Stable structure and good pore quality
Reinforced box type mast+large section slewing support+extendable track, with strong stability and guaranteed verticality.
Parallelograms with variable amplitude allow for fast hole alignment and precise leveling, making it less likely for beginners to deviate from the hole.
Reliable configuration and moderate fuel consumption
Engine: Cummins QSF3.8 (86 kW/117 horsepower), National IV emission, durable, fuel-efficient, and easy to start at low temperatures.
Hydraulic: a mainstream international brand with stable operation and low failure rate, much more worry free than miscellaneous machines.
