The KR90C rotary drilling rig is a compact and highly efficient foundation equipment designed for urban and confined construction sites. Built on a reliable Caterpillar undercarriage (CAT C4.4 engine), it combines world-class hydraulic control technology with APIE’s expertise in piling machinery manufacturing. The KR90C is ideal for small to medium-sized projects requiring flexibility, productivity, and reliability.
Work stably-combined action of counterweight frame and ground anchor fix the bottom of oscillator to the ground firmly and reduce the reaction torque generated by oscillator to rig.
The KR360C is a high-torque, heavy-duty rotary drilling rig built on a CAT base chassis, designed for large-diameter and deep foundation construction. With a maximum torque of 360 kN·m and drilling depth up to 94 meters, it is ideal for demanding projects such as bridges, high-rise buildings, and diaphragm walls. The machine supports a full range of drilling tools and is available in remanufactured used condition, backed by professional servicing and warranty.
