High‑power power reserve SANY SR235 Rotary Drill Rig

Power and Drilling Performance

Rated torque of 235kN · m, efficient drilling can be carried out in soil layers, soft rocks, and moderately weathered rock layers. The power head torque speed can be adjusted, suitable for clay, sand layers, pebbles, mudstone and other formations
15 meter long full stroke compression, with a compression force of 210kN and a lifting force of 270kN; can lower a 15m long casing at once, very suitable for bite pile, deep casing, backfill layer, and soft soil foundation construction. The casing has strong lifting capacity
Optional Isuzu/Volvo engines with stable power output; National III/Euro V emission versions are optional, with economical fuel consumption performance. The measured fuel consumption under soil conditions is about 26L/h

Multi method, one machine, multiple uses

Standard Kelly rod rotary excavation method
CFA long spiral construction method, no need for casing guide holes
Low clearance mode: The mast can be lowered in height for construction in confined spaces under bridges, inside factories, and tunnels
Expansion: Squeezing pile, single axis deep mixing pile, quick switching of accessories and construction methods, higher equipment utilization rate

Intelligent control and durable design

Visual monitoring of drill pipes, real-time display of pressure station position to prevent damage to drill pipes due to misoperation; Floating pre tightening function reduces the wear of drill rod locking teeth and extends the service life of drill rods
The compound action is smooth, the lifting speed is fast, and the efficiency of lifting and pouring soil is high.
Centralized automatic lubrication system, easy maintenance, reduces manual maintenance.
Heavy duty widened track chassis, reasonable overall weight distribution layout, high stability in deep pile and large pile construction, and good anti overturning performance.
