TYSIM KR250CS Low Headroom Drilling Rig
 
The KR250CS from TYSIM is a compact, fully‑electric‑control low‑headroom rotary drilling rig — purpose‑built for piling and foundation drilling tasks in sites with limited overhead clearance. With a powerful 250 kN·m torque, a drilling capacity up to 2,000 mm diameter, and a maximum drilling depth of approximately 31.2 m, the KR250CS delivers substantial foundation performance in tight or restricted spaces.
 
Key Capabilities & Features
Low‑headroom, compact design — engineered for environments where traditional high-mast rigs cannot operate, such as under bridges, overhead utilities, inside buildings, or other sites where vertical clearance is constrained. 
Strong drilling power & versatility — with 250 kN·m torque and up to 2,000 mm drilling diameter, the rig is capable of boring large-diameter piles and foundations, even in challenging soil or subsurface conditions. 
Reasonable drilling depth for many foundation applications — max depth of ~31.2 m makes KR250CS suitable for a wide variety of piling tasks without needing overly tall rigs. 
Fully electric‑control rotary system — ensuring precise operation, efficient control, and smoother piling cycles even in confined working environments. 
Adaptable to diverse foundation projects — ideal for urban construction, building footings, bridge or overpass substructures, under‑bridge foundations, and other scenarios where space and clearance are restricted but foundation strength is critical.
 
Typical Applications
Urban residential or commercial construction where overhead height is limited (e.g. under existing structures, garages, or near utilities).
Bridge or overpass piers, under‑bridge foundations, or highway/rail infrastructure projects requiring deep, stable piles in tight spaces.
Tunnel entrances, underpasses, or other civil‑engineering works with low vertical clearance.
Industrial or retrofit projects beside existing installations, where a compact drilling rig must deliver high-performance drilling without disrupting the surroundings.
 
Why Choose KR250CS
KR250CS offers a balanced solution: compact footprint + robust drilling capacity + operational flexibility. For contractors facing the common challenge of restricted site headroom, this rig ensures they don’t have to trade off drilling power or foundation integrity. Its fully‑electric control and reliable design make it a cost‑effective, versatile, and safe choice for modern foundation works in urban or constrained environments.
