Royal Eijkelkamp has developed a state-of-the-art drilling system to extract core samples from the coarse granite from railway beds and the soil below. There is a need to know more about this material. Higher train speeds, heavier loads and a growing interest in the dangers of pollution, make sampling necessary.
Taking samples of the large and hard granulates of 1.18-3.94in (30-100mm) present in railway tracks is very difficult. Royal Eijkelkamp has developed a sampling technique that gives you a reliable core and a high recovery rate for this material.
The heart of this specialized system is our sonic drill head. Two eccenters, driven by high-speed hydraulic-motors generate a high-frequency (~180 Hz) vibration. This vibration facilitates the intrusion of the sampler into the coarse granite material. The vigorous but hardly visible vibration produces a strongly reduced friction. Inertia effects care for a near 100% recovery rate of the sampled material.
