Smooth combined movements SANY SR150 Rotary Drill rig

Power and hydraulic system

Equipped with imported Isuzu engine, with load adaptive speed regulation, the fuel consumption is reduced by 5-10% compared with the old model, and the stability under high temperature working condition is strong. LUDV load-sensitive hydraulic system is adopted, the flow is distributed as required, the action response is smooth, the core hydraulic component is imported, the oil leakage failure rate is low and the durability is high. The power head is equipped with special lubrication structure and removable key bar, which extend the service life of wearing parts and reduce the maintenance cost in the later period.

Complete machine stability and construction accuracy

Expansion and widening crawler+low center of gravity counterweight layout, dead weight of 46t, excellent anti-overturn capacity in narrow site. Standard mast automatic plumb adjustment, tilt alarm, complete machine balance monitoring, high hole perpendicularity accuracy, and reduction of scrap pile rework risk. The parallelogram luffing mechanism is not easy to deflect the mast angle during displacement, and the alignment speed is fast.

Mobile turnaround advantages

The lightweight and compact design of the machine body is suitable for the construction of urban construction sites, villages in cities and narrow municipal road sections; Easy disassembly and assembly, high transfer efficiency, lower requirements for access road and site space than medium and large models, and saving time and money for short-distance site relocation.

Control and intelligence

CAN ‑ BUS complete machine monitoring, fault self-inspection and parameter visualization; Pilot handle operation, light force. Five-level shock absorption in the cab, wide vision and low fatigue after long-time operation. Booster cylinder supports standard/fast lifting dual mode, with higher lifting efficiency.
