High construction efficiency SANY SR285 Rotary Drilling Rig

Strong rock ability

285 kN · m high torque+260 kN compression, the construction efficiency of hard rock/strongly weathered rock is 10% higher than that of the same level.
The sixth generation reinforced drill pipe and integral pressure platform are resistant to vibration and fatigue when entering the rock, and the structure does not crack after 20000 hours.
Heavy duty reducer+large-sized slewing bearing, high reserve factor of key components, suitable for high load rock working conditions.

High construction efficiency and short construction period

17 meter full stroke pressurization, single pressurization to the end, no need to repeatedly reverse the rod, and the drilling speed is increased by 30%.
The pressure hoisting speed is 21 m/min, which is three times that of ordinary models, and the lowering/lifting of the casing is faster.
Step drum design, single layer winding of machine lock rod steel wire rope, increased lifespan by 35%, reducing downtime and rope replacement.

Intelligent energy-saving, low operating costs

Real time power distribution technology, fast composite action response, low fuel consumption, annual fuel savings of 60000 to 100000 yuan.
Automatic vertical adjustment+precise depth measurement (± 1.5 cm), high one-time pass rate for pile forming, and minimal rework.
Multi mode options: Standard/Low Clearance/CFA Long Spiral, one machine for multiple purposes, covering a wider range of operating conditions.
