CRT-T4 Dedicated Coring Trailer

Hydraulic proportional drill feed mechanism ‘automatically’ ensures the fastest drill feed at optimum cutting speed

CRT-T4 Dedicated Coring Trailer options:
Option 1- Hatz Diesel engine IB40
Option 2- Honda Petrol engine GX390

To carry out any form of testing straight & clean sided core samples are required. Vibration of a diamond core drill during the coring process will result in a badly finished core that will need to be ‘dressed’ before any meaningful testing can be carried out. In addition vibration of a core drill will also quickly damage the diamond cutting face by erosion of the individual diamonds resulting in rapid wear rates. Coring should always be carried out using a rigid, stable & vibration free operating platform to ensure the integrity of core samples. CRT-T4 is a self contained remote controlled hydraulically driven diamond drilling trailer for taking core samples in roads or airport runways with concrete or asphalt surfaces. An hydraulically driven coring trailer provides consistent rotational torque when drilling in a variety of materials such as concrete, brickwork, rock or asphalt & steel re-bars.
