AI Description
BetaCapabilities
The Klemm KR 802 is a compact hydraulic crawler drilling rig designed for foundation work, soil investigation, and small-to-medium drilling projects. Powered by a CAT diesel engine producing 110 hp, it features a sophisticated four-circuit hydraulic system with up to 250 bar pressure, enabling precise control for rotary drilling operations. The tracked chassis provides excellent stability and low ground pressure (5.3 N/cm²), making it ideal for sensitive terrain and confined job sites.
Industries & Uses
This rig serves construction companies, geotechnical firms, and civil engineering contractors performing borehole drilling, foundation testing, and geological surveys. It's particularly valuable for projects where access is limited or ground conditions are delicate—think urban renovations, archaeological surveys, or environmental assessments. The compact 2.2 m width allows work in tight spaces that larger rigs cannot reach.
What to Check When Buying
When evaluating this used 2001 model, prioritize inspecting the hydraulic system thoroughly: check all hose connections for leaks, verify pump performance against the stated flow rates, and review maintenance records for fluid changes and filter replacements. Examine the crawler tracks for wear and proper tension, test the diesel engine's cold start reliability, and confirm the drilling mast's structural integrity and alignment. Request service history documentation and operational hours to assess remaining component lifespan.
