Fast dynamic response SANY SR280R Rotary Drilling Rig

Outstanding rock penetrating ability

The maximum torque is 280kN · m, the pressure is sufficient, and the overall weight of the machine is sufficient. It has obvious advantages in dealing with strongly weathered, moderately weathered rocks, pebble layers, and limestone; Equipped with an adaptive control system for geological formations, intelligent matching of torque, speed, and pressure, automatic adjustment of soft and hard geological formations, reducing frequent parameter switching by operators, and improving rock entry efficiency compared to domestic models of the same level.

Reliability upgrade of power head

The power head is equipped with a built-in buffering and shock-absorbing structure, which greatly absorbs drilling shock and vibration, and greatly improves shock absorption performance; The service life of reducers and motors has been significantly extended, and the failure rate of hard rock continuous construction is lower, making them suitable for long-term continuous pile foundation operations.

Mast and structural stability

Optimized truss mast with high stiffness and strong fatigue resistance, passed professional fatigue testing; Re optimize the amplitude mechanism, lower the center of gravity of the entire machine, reduce drilling shaking, and improve the verticality of the borehole; Balance the stress at the hinge point to reduce the risk of structural cracking.

Multi working condition adaptability

The maximum depth of the machine lock rod is 54-56m, and the friction rod can reach 84m; the maximum aperture is 2.2-2.5m, covering the vast majority of building, municipal, and bridge pile foundations;
Optional tube rolling machine and CFA long spiral kit, one machine for multiple purposes, suitable for dealing with quicksand, karst cave prone collapse formations;
Derived version SR280LH short mast model, suitable for transportation and construction in mountainous areas and low terrain.
