Ample torque SANY SR155 Rotary Drill Rig

Power&Drilling Performance Advantages

Fifth generation adaptive power head with abundant torque
Rated torque of 155kN · m, supporting 6-speed adaptive formation; High speed soil throwing in soft soil layers, pebble/soft rock gear twisting, with double buffering and shock absorption, thickened wear-resistant gears, impact resistance, and less likely to damage the gears. Apply a pressure of 155kN and a lifting force of 160kN on the main coil, making it difficult to drill deep holes with high lifting resistance.
Mitsubishi D06FRC TAA engine, with a high power of 147kW and sufficient power reserve; High flow electric control hydraulic system, smooth composite action, synchronous operation of rotation, drilling, and hoisting, fast drilling speed, and a single pile in conventional soil layers can be completed in only about 2 hours
The standard maximum drilling diameter is 1.5m and the deepest drilling hole is 56m; with the help of Sany customized drilling tool construction method, it can handle 2.4m shallow aperture power piles and has strong working condition expansion ability

Flexible body and convenient transfer and transportation

The whole machine weighs 48t and is compact in size; The transportation width is 3100mm, the height is compliant, and there is no problem of excessive height and width on urban roads. It can be transported without splitting the mast.
The track is extendable with a width of 4100mm, allowing for flexible positioning in narrow urban tunnels, mountain tower construction sites, and small foundation pits in residential areas; The mast supports a tilt angle of 5 ° -90 ° for forward and backward, and a tilt angle of ± 3 ° for left and right. The construction of slopes and inclined piles is convenient, making it very suitable for power grid pile foundation projects that require frequent machine relocation

Fuel efficient, low-cost, and easy to maintain

Intelligent power distribution hydraulic system, outputting power as needed; The average fuel consumption in actual working conditions is only 14L/h, and the fuel economy of similar models is excellent. Long term work saves a lot of fuel costs
The mast and drill rod are made of high-strength wear-resistant steel, and the structural components have undergone fatigue testing with minimal cracking and deformation; The whole machine has ample maintenance space, centralized hydraulic pressure measuring points, time-saving daily maintenance and troubleshooting, sufficient spare parts in the market, and low maintenance costs.
