Multi-speed Power Head Zoomlion ZR240G Rotary Drilling Rig

Medium hard rock strength, wide geological adaptability

240-260 kN · m torque+multi speed power head, can stably drill into 40-50 MPa moderately weathered rocks (limestone, sandstone), with fast footage in pebble/sand layers.
Equipped with high-strength drill pipe with a diameter of 440mm as standard, the deep hole (50-70m) has good torsional rigidity and is not easy to shake.

High efficiency, fast pile completion

Cummins 254 kW+high flow Kawasaki hydraulic, with smooth compound action, φ1.5–2.0 m、 The efficiency of piles with a depth of 40-60 meters is outstanding.
Mid mounted single row main winch+high-speed lowering, reducing drilling/unloading time by 25%, prolonging the service life of steel wire rope, and reducing downtime due to rope replacement.

Good stability and sufficient safety

Enhanced telescopic chassis with low center of gravity design, large grounding area, stable construction on soft/steep slopes, and strong anti overturning ability.
Double rotary reducer, high parking torque, locked rotation without shaking during rock drilling, verticality control ≤ 1/200.
Mast with large angle oil cylinder support and dual buffering to protect the drill rod and power head; Standard configuration includes 360 ° monitoring, one click vertical adjustment, and bottom protection.
