The KR125A rotary drilling rig is engineered with advanced design concepts focusing on operational convenience, reliability, and drilling accuracy:
-
Transport & Working Transition: Single-load transportation design allows rapid switching from transport mode to operation mode.
-
Hydraulic & Control System: Developed in cooperation with Tianjin University CNC Hydraulic Institute of Technology, ensuring efficient performance and real-time monitoring.
-
Structural Optimization: Single-cylinder luffing mechanism and automatic docking/folding two-stage mast improve stability, efficiency, and reduce manpower.
-
Drilling Accuracy: Innovative drilling bucket depth measurement system and automatic mast vertical adjustment enhance hole precision.
-
Reliability & Durability: Advanced rotary angle displacement output system, reversible driving head to double lifespan, and multi-stage damping technology for improved construction accuracy.
-
Safety: Main winch bottoming protection with priority control, plus innovative “Wind-Fire Wheels” design for safer night operations.
-
User-Friendly Design: Rear space optimization increases storage capacity, while the new two-stage operating interface provides more convenient and intuitive operation.
The KR125A is widely applied in urban construction, foundation treatment, bridges, and high-rise building projects, offering reliable performance for demanding foundation engineering tasks.
