Stable hole-forming quality SANY SR235 Rotary Drill Rig

Power and drilling performance advantages

Abundant power reserve and strong versatility in complex geological formations
Equipped with Isuzu 6UZ1 engine, 257kW high power; The power head has multiple adjustable speeds ranging from 5-32 rpm, allowing for rapid rotation in soft soil and low-speed, high torque drilling in gravel/weathered rock. It can handle clay, sandstone, gravel, and strongly weathered rock layers.
Strong pressure and pulling ability
The standard pressure is 210kN, and the lifting force can reach 270kN. The new W10 has a maximum pressure stroke of 15m, which is suitable for long casing construction. The biting pile and full casing can be easily and effortlessly pulled out by Sany Group.
High hoisting efficiency
Main winch tension is 235kN, with a maximum speed of 70m/min; Single layer drum steel wire rope arrangement, the steel ropes will not be squeezed and worn against each other, and the service life of the steel wire ropes will be greatly extended, reducing consumables expenses

Reliable structure, durable, low failure rate

The mast and variable amplitude bracket are made of thickened high-strength steel structure. After fatigue testing, the structure is not easily cracked or deformed after 20000 hours of normal working conditions;
The heavy-duty specifications of the power head reducer are equipped with anti mud seals, which prevent mud from easily entering the gearbox;
Scalable track: with a retracted width of 3.54m for easy transportation by flatbed trucks, and a unfolded width of 4.5m, the entire machine has sufficient weight of 81 tons, and deep hole operation has excellent anti overturning and stability
The mast supports forward and backward, left and right tilt angle adjustment, with a long guiding structure and high precision in drilling verticality.

Hydraulic system, fuel-efficient and efficient

Electro hydraulic positive flow control system, intelligent power allocation, and reduced useless power consumption loss; The compound action is smooth, and the lifting, rotation, and pressurization can be operated synchronously, with a fast drilling cycle speed;
The engine has multiple modes, switching between heavy-duty, standard, and economy modes. The economy mode is activated in urban ordinary soil layers, and the overall fuel consumption is better than that of competitors in the same class.
