Powerful in drilling SANY SR285 Rotary Drill Rig

Strong drilling and drilling performance

Rated torque: 285kN · m, standard configuration: 6th generation mechanical lock/friction dual purpose drill pipe, with integral locking mechanism and reinforcing ring, material upgrading, rock stratum drilling efficiency increased by 10%
The maximum pile diameter is 2300mm, the maximum depth of friction rod is 94m, and the mechanical locking rod is 61m; the pressure of 260kN is added, and the adaptability of strongly weathered, hard soil layer and secondary solid rock is good, which is suitable for bridge and deep house building piles.

Special chassis with high stability

Sany self-developed special expansion and widening chassis for rotary excavation, large-diameter roller slewing bearing; The mast is of box structure, which is resistant to torsion and fatigue. The whole machine for deep-hole operation has small shaking and high hole forming perpendicularity.
The whole machine has about 100t counterweight and excellent stability in soft and hard foundation operation.

Power system, fuel-saving and durable, good oil adaptability

Isuzu high-power electric control engine is equipped with power dynamic optimal control, with smooth compound action, power distribution as required, and reduced air consumption and fuel consumption.
Three-level fuel oil filtration system, lower failure rate of poor oil field.
