Standard is the VKG – 6, i.e. a 6 m length of cores. The maximum inner diameter is 102 mm (barely or by using a plastic hose, with PVC-liner inserted 96 mm, transparent ones are available too). System may be switched to 3 m core barrel length, further easing all handling and operating proceedures.
- Variable coring speed, frequency and depth (2 – 6 m)
- Maximum vibrating force 3 „tons“ (30 kN)
- Operation depth up to 1000 m
- Realtime measure of penetration (USB output)
- Reliable operation at minimum maintenance
- Unique folding and dismantling
