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.
Spherical hobs are very mature and are widely used in many equipment, such as rotary drilling rigs, RCD, pipe jacking machines, etc. By analyzing the use of ball-tooth hobs on the above equipment, it can be known that when there is sufficient propulsion pressure and the rock layer strength is about 130MPa, the footage speed of the spherical tooth hob can be maintained at 0.3~0.5m/ h. And the footage speed is relatively stable. When the spoil discharge is sufficient, the service life of one spherical tooth hob can reach a construction length of 300m.
The KR250ES Low Headroom Hydraulic Piling Rig is a high-performance foundation drilling machine specially designed for projects with height restrictions. Combining robust torque capacity with a compact structure, it is ideal for construction work in urban environments, under bridges, or inside industrial buildings. Engineered by top industry standards, the KR250ES delivers reliable, efficient, and precise piling solutions where traditional rigs cannot operate.
