Reinforcement of key structures SANY SR280 Rotary Drilling Rig

Power and rock entry advantages

The rated output torque is 280kN · m, and the power head is equipped with a reinforced buffer structure, greatly improving shock absorption. The reducer and motor have a longer service life, and the rock penetration ability of moderately weathered, partially slightly weathered hard rock, and limestone cave formations is strong, with stable rock penetration efficiency
High power Cummins engine, sufficient power reserve, adaptive electronic control, can automatically match torque, speed, and pressure according to the formation, reduce drilling tool loss, and save the cost of roller and cutting consumables
Optional matching casing, cylinder drill, core drilling tools, good adaptability to karst caves, quicksand, and collapsed formations, high verticality of borehole formation

Stable structure and strong durability

Optimization of mast and large triangle amplitude mechanism, high structural stiffness, resistance to deformation and shaking, good stability for deep hole and hard rock operations; There is also the SR280LH low mast heavy-duty version, suitable for mountainous areas and height limited construction sites
Self made wear-resistant machine lock rod/friction rod, high-strength wear-resistant key strip, long service life, stable welding process, low structural failure rate
Widening the heavy-duty track chassis, reasonable ground pressure ratio, less likely to sink on soft foundation construction sites, reasonable weight distribution of the entire machine, and no floating during heavy load operations
