Seven Benefits to Improve your  Drill Dri lling ing Effe c tiveness 

Safe and fast rod handling. Automa Automatic tic synchronisation between chuck and rod holder hol der..



A choice o f three rotation units units to ensure optimal torque and speed. Easy to convert from one to the other. Easy to adapt for different diameters and geological conditions.



Simple and reliable reliable chuck . Very few moving parts, widely adjustable gripping force, easy to service. 76 mm (N-size) (N-si ze) core barrels pass through the chuck spindle, 131 mm core barrels through the rod holder ho lder..



quic ick k rod rod Double feed cylinders. For qu handling at all depths. Can be set for slow feed, high force (two active cylinders) or high speed, low force (one active cylinder).



Drill in any direc tion (See Drill (See Fi Fig. g. 1,2,3 a nd 4) Standard equipment includes a manually operated turntable and worm gear. For easy positioning an optional hydraulic powered worm gear is available. Strongly recommended when the drill rig is fitted with feed version 3300.

Drilling Capacity Guide

 Three different stroke lengths are available, 850, 1800 and 3300 mm. The feed movement is achieved by two hydraulic cylinders and chain system. It is possible to select between high speed/low force or slow speed/high force by activating one or both feed cylinders. Data, feed version

 The chuck and the rod holder are synchronized by an integral sequential logic system for safe and easy rod handling.  The rotation unit can easily be swung aside for off-hole clearance. Rotation speed and axial holding force of the chuck are adjustable from the control panel. Easy conversion between Standard >High torque >Heavy duty rotation units.

DIAMEC® 262SKIDSPECIFICATIONS Power units 45E and 40DT with double hydraulic pump  The power unit has two variable-flow hydraulic pumps, mounted in tandem. They are integrated in the hydraulic system in such way as to adjust their output to the power requirements of the drill unit in a most efficient way. Connections for an optional hydraulic driven flush pump are standard. Supplied complete with 70 litre oil tank, oil cooler and filters.  The electrical power unit 45E is powered by an asynchronous electric motor, and the diesel power unit 40DT with a Deutz turbo diesel, type BF4L 913.
