Fast dynamic response SANY SR200 Rotary Drill Rig

Torque matching for small and medium-sized pile foundations, with outstanding efficiency in soil layer construction

Rated 200kN · m power head torque, suitable for apertures within 1.8m and pile depths up to 60m, fully covering small pile foundations in residential, municipal, and factory areas; With a wide speed range of 7-26rpm, drilling in soft soil, silty clay, and a small amount of moderately weathered rock is smooth, and the construction efficiency of machines of the same level is improved by 10%.

High speed main winch saves time in lifting and releasing drilling tools

The main winch merging technology has a maximum lifting speed of 72m/min and a lifting force of 200kN. It has fast lowering and soil lifting speed, shortened single pile cycle period, and is less likely to collapse or shrink in loose formations, with high drilling accuracy.

Long term pressurization system, stable drilling

The 4300mm long stroke pressure cylinder has a maximum pressure of 150kN and a lifting force of 160kN. The pressure is continuously stable, and the drilling in deep holes and soft formations does not deviate. The verticality control of the hole is better.
