The KR250CS Low Headroom Hydraulic Piling Rig is a high-performance rotary drilling machine specifically engineered for construction in space-constrained environments, such as beneath bridges, inside industrial buildings, or in subway and basement projects.Combining powerful torque output with a compact structure, the KR250CS overcomes the limitations of conventional rigs in low-clearance conditions, making it the ideal solution for urban foundation engineering. Its modular design, robust construction, and intelligent control system ensure maximum drilling efficiency and operational flexibility.
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.
Photovoltaic drilling rig is an efficientdrilling rig developed by our companyin responseto national calls and marketdemands for the construction of solarphotovoltaic piles,which can changeconstruction modules according to differentconstruction requirements.
Pipe jacking machines use shield technology to excavate soil or rock with a rotating cutter head, removing the excavated material via a mud conveying system while hydraulic jacks push precast pipes into the tunnel and grout stabilizes the walls.
These machines are applied in diverse municipal and civil projects, including building underground water supply/drainage systems, installing gas pipelines, optical cables, and constructing subway tunnels, minimizing surface disruption.
Regarding types, the slurry balance machine suits various soil and high - groundwater conditions; the Earth Pressure Balance Machine is for soft to medium - hard soils; and the rock machine, equipped with powerful tools, is for rock formations and even mixed soil - rock conditions. They are key to modern underground construction.
KR150D is engineered for exceptional performance and versatility, featuring a powerful USA Cummins engine and a customized high-power dual-drive power head. Built on a newly upgraded Caterpillar chassis, it boasts light weight, easy operation, and strong travelling traction for smooth mobility across job sites. The customized short mast effectively lowers the center of gravity to enhance stability, while the new-generation electronic control platform ensures precise operation. With both GB certification and EU EN 16228 standard certification, KR150D meets strict quality and safety requirements for global construction applications.
APIE AHG Series Hydraulic Grab is a product developed and designed based on decades of experience in diaphragm wall construction and equip-ment development in China.It addresses various issues encountered with similar equipment during construction, adapting to complex geological conditions both domestically and internationally.This helps reduce customer usage costs and create value for clients.
