Hydraulic proportional drill feed mechanism ‘automatically’ ensures the fastest drill feed at optimum cutting speed
CRT-HCT Heavy Duty Coring Trailers:

Option 2 – Lister 17.5HP Diesel engine D-15-400
Option 3 – Lister 27HP Diesel engine D20-600
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.
Cooper Heavy Duty Core Drilling Trailers CRT-HCT are self contained coring machines that provide a rigid and stable drill platform for all types of coring in a wide variety of asphalt & concrete surfaces. The proportional hydraulic feed system provides for a rapid but safe drill penetration with minimum core bit wear rate.
