Products Description
The RCF260C rubber crawler portable water well drilling rig is designed for projects that require frequent movement between drilling locations. The rubber crawler chassis allows the machine to travel smoothly across urban roads, rural paths, muddy ground, and uneven terrain, while reducing surface damage compared to traditional steel tracks.
With a drilling depth of up to 260 meters and borehole diameters ranging from 90 to 350 mm, this equipment is suitable for groundwater wells, agricultural water supply, and general geological drilling. The adjustable drilling angle from 75° to 90° makes it easier to adapt to different site layouts, especially in areas where positioning space is limited. Its compact structure also helps simplify transport and relocation between job sites.

Working Principle
The RCF260C rubber crawler portable water well drilling rig operates through a hydraulic system that controls rotation, feeding, and lifting. During drilling, the impact hammer delivers continuous force to the drill bit, while the drill rod rotates from the surface. This combination allows the rig to break through soil and rock layers step by step.
At the same time, drilling fluid or compressed air is delivered through the drill rod to the bottom of the hole. This flow carries cuttings back to the surface and prevents material from accumulating inside the borehole. By maintaining a clear drilling path, the system allows the operation to continue without interruption, even in mixed or unstable ground conditions.
Core Components
Core Components
Power System:
The rig is equipped with a 76KW engine that provides sufficient output for deep drilling operations. In actual use, this ensures stable power supply when drilling into deeper layers or encountering increased resistance, reducing the need for frequent adjustments.
Hydraulic System:
A high-torque hydraulic motor works together with large-diameter cylinders to control feeding, lifting, and rotation. This allows operators to adjust drilling parameters based on ground conditions, such as increasing torque or feed pressure when working in harder formations.
Impact and Rotation Mechanism:
The impact hammer and rotation system work together to break rock efficiently. The hammer can adapt its working intensity depending on formation hardness, while the rotation system maintains steady movement of the drill rod, helping keep the borehole consistent.
