CF8

The TesCar CF8 is a premium drilling-rig engineered for demanding deep foundation projects where performance and accessibility are critical. Built on a compact crawler base, this specialized piling equipment delivers exceptional drilling power in a footprint that fits restricted jobsites where standard rotary rigs cannot operate. With a total operating weight of 28,000 kg and powered by an Isuzu Stage V diesel engine producing 89.2 kW, the TesCar CF8 specifications balance power efficiency with mobility, making it ideal for contractors tackling challenging bored pile installations across confined urban environments and difficult terrain. The TesCar CF8 drilling-rig features a high-torque rotary head capable of 100 kNm nominal output, supported by dual crowd systems combining hydraulic rams and chain-motor assemblies for precise depth control and extraction. Dual winch systems (80 kN primary, 50 kN auxiliary) manage heavy kelly bars and oversized drilling components, while variable speed capabilities—including 30 rpm drilling and 60 rpm spinoff modes—enable efficient performance across different soil conditions. This drilling-rig accommodates kelly bar bored piling to 2,500 mm diameter at depths exceeding 40 meters, while CFA capabilities extend to 750 mm diameters. The TesCar CF8 specifications include innovative low-headroom operation modes for applications where mast height restrictions apply, achieving effective drilling depths of 22 meters with standard configuration and 18 meters in super low-headroom mode. This versatility makes the TesCar CF8 an essential choice for basement construction, underpinning, and foundation work in space-constrained locations where conventional large-diameter drilling equipment cannot be deployed.
