Precise alignment with holes SUNWARD SWDM220 Rotary Drilling Rig

Dynamic and Drilling Performance

KN ・ m large torque power head, sufficient torque reserve, suitable for construction in moderately weathered rock stratum and hard soil layer; The rotating speed range is 6 ‑ 28rpm, which can be flexibly adjusted according to the stratum. The high-speed soil throwing function can be selected, so the soil lifting efficiency is higher.
Cummins QSL9 ‑ C325 engine, with power of 242kW, sufficient power and strong adaptability to high and cold plateau conditions; Electronic hydraulic system has low pipeline loss, high transmission efficiency, economical oil consumption and lower long-term construction and operation cost
The maximum pressure of the pressure winch is 210kN and the lifting force is 240kN; the lifting force of the main winch is 230kN, the maximum lifting speed is 70m/min, and the deep hole lifting speed is fast, which is suitable for deep pile operation; The maximum hole diameter is 2000mm and the maximum pile depth is 69m (54m configuration), covering most housing construction, municipal and high-speed railway pile foundation projects

Stability of chassis and complete machine

Shanhe self-developed reinforced expansion chassis, crawler expansion width 3000 ‑ 4500mm, wide crawler grounding area, stable 360 ° rotation construction; Reinforced substructure, torsional and durable, low failure rate.
High-strength box drilling mast with strong deformation resistance; Double-cylinder luffing mechanism and large triangle supporting structure, small overturning moment of the whole machine during drilling, small shaking during hard formation construction and more stable perpendicularity; Concealed outriggers further improve drilling stability and facilitate chassis maintenance.

Site adaptability and transition advantages

The body structure is compact and compact, the traffic capacity of narrow site is excellent, the advantages of old urban reconstruction, narrow construction site in the community and road red line are obvious, and the site adaptability of the same torque model is outstanding
The whole machine can be directly transported with the drill pipe, without dismantling the drill pipe, greatly reducing the dismantling time and hoisting cost, and the cross-site transfer efficiency is high, which is suitable for multi-point flow construction of the project.
