Strong power SANY SR445 Rotary Drill Rig

Strong drilling ability and extremely adaptable to hard rocks

445kN · m high torque+400kN super large pressure, can stably drill into 80-90MPa slightly weathered granite and limestone, preferred for bridge, high-speed railway pile foundation karst cave, and rock socketed pile construction
The dual stroke pressurization system can be freely switched: a regular stroke of 10m is suitable for hard rock drilling, and a super long stroke of 21m is suitable for long casing placement construction in backfill soil and gravel layers. It can accommodate both soft and hard strata
The fifth generation heavy-duty power head comes with an adaptive matching system for rock entry, automatic linkage of torque and pressure, optimized gear for roller drilling, and higher efficiency in rock crushing.

Energy saving and fuel-efficient, with lower operating costs

Equipped with Sany adaptive power distribution hydraulic system, power is output as needed, and the composite action is smooth without energy consumption waste; The comprehensive fuel consumption is 10% to 15% lower than its competitors in the same class, and the fuel cost for pile foundation construction is significantly reduced throughout the year; The National Isuzu large displacement low-speed engine has the best fuel consumption performance under heavy load conditions with high torque at low speeds.

Stable structure and durability, fully loaded

162 tons of super large self weight+widened special pile foundation chassis, with a sinking center of gravity, the 100 meter deep pile and large-diameter drilling machine do not shake, and the anti overturning ability is excellent;
The main winch adopts a single-layer wrapped steel wire rope structure, which has no compression friction and a 35% increase in service life, significantly reducing the cost of rope replacement consumables;
The entire vehicle is equipped with shock resistant and thickened structural components, optimized for frequent rock vibrations. The structural design has a lifespan of over 20000 hours and a high resale value in the industry.
