Heavy Duty Core Drilling Trailers

Upgraded model CRT-T1 Towable Core Drilling Machine available, please click here

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

CRT-HCT Heavy Duty Coring Trailers:
Option 1 – Honda 17.5HP Petrol engine P15-400
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.

Key Features

  • 10 hours of normal working is possible with the 27 litres (7 gal) fuel tank & 400 (105.6 gal) litre water tank
  • Drill depths of 600 mm (23.62 inch) or 1000 mm (39.3 inch) as standard with extension bars for deeper drilling
  • Proportional’ feed system allows fast & safe coring even through steel re-inforcement bars
  • ‘Automatic’ Soft Start Drilling feature ideal for inexperienced operators
  • ‘Two-function’ Emergency Stop prevents any run-on of the drill whilst the engine is stopping
  • Power take-off facility for driving a hydraulic road breaker or hydraulic tamper
  • 103 dB Maximum noise level

Key Uses

  • Medium duty coring in both asphalt & concrete surfaces
  • Heavy duty coring in both asphalt & concrete surfaces
