torsion and bending resistance SANY SR155 Rotary Drilling Rig

Flexible transition, high cost-effectiveness for short distance construction

The weight of the whole machine is moderate at 46 tons, and it can be directly transported by ordinary large trucks. It has obvious advantages in passing through mountainous areas, rural roads, and narrow construction sites. The transfer and disassembly time is short, and it is suitable for scattered and small scattered pile foundation projects.

Energy saving and fuel-efficient, with low operating costs

Intelligent matching of engine and hydraulic system, with an hourly fuel consumption of only 12-16L under pure soil conditions, resulting in lower fuel expenses for long-term rental and small-scale pile foundation projects; The maintenance parts have small specifications, and the cost of purchasing filter elements and engine oil is cheap.

Durable structure, lightweight and high-strength design

Robot welding of structural components of the whole machine box, non-destructive testing of key welds; The integrated X-shaped lower frame is resistant to torsion and bending, and is not easily deformed or cracked during long-term backfilling with soil and shallow gravel construction; The main winch is arranged with a single row of ropes, and the wear speed of the steel wire rope slows down.

Intelligent electronic control, easy and safe operation

The cab is equipped with a large-sized monitoring screen that displays real-time data on torque, pressure, drilling depth, and verticality; Standard features include automatic drilling cruise control, mast automatic sag adjustment, drill rod overload protection, and maximum protection against winch impact; The joystick has light force, making it easy for beginners to master in a short period of time.
