Positioned at the top of the drill string, the Kelly Bar primarily serves to transmit torque and bear the total weight of the drill string. It is a critical component for ensuring the stable operation and precise penetration of drilling equipment in numerous fields, including oil drilling, construction foundation boring, and mining. Its efficient torque transmission enables the drill bit to power through various soil and rock formations, guaranteeing the smooth progression of drilling operations.
The chain knife underground diaphragm wall forming machine is a powerful tool for underground foundation construction, widely applied in various projects such as construction and revetment works. It mixes the original soil and injects grout through chain saw cutters to form continuous, flat, and uniformly thick walls. These walls exhibit excellent water-stopping performance, with a permeability coefficient of up to 1×10⁻⁷ cm/s or even lower. Paired with high-precision inclinometers, it ensures that the verticality error is ≤1/250.
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.
Extended-range electric dynamic compaction crane is an electric dynamic compaction product launched proactively by APIE in line with the national strategy and the market demand. the Eextended-range electric dynamic compaction crane is more eficient, reliable and intelligent while maintaining lower consumption.
The Hydraulic Pile Breaker is user-friendly, requiring no special skills for operation. This reduces the risk of accidents and makes it accessible to a wide range of operators. Additionally, its maintenance is straightforward. The oil temperature should be kept below 70 °C, with the optimal operating temperature range being 35 - 55 °C. Under special conditions, proper heating or cooling measures should be taken.
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.
