UNDERGROUND DIAMOND CORE DRILL RIGS

Track Mounted Underground Diamond Core Drill Rig MM517c

High performance underground Core drill rig model Mini-Max 517-c on a track mobile.

Underground core drill rig model MM517 C

This drilling rig is specially built for underground purposes. It could be dismantled at the surface and down to down to the mine through shaft lift with small dimension and then reassembly in place. Very easy and quick operation (less than 4 hours), everything is identified. As requested for underground conditions, the Rotary actuator allows and covers a lateral drilling area of 360°. Another advantages of MM517-c drill rig are its simplicity (fully hydraulic operations); pullback capacity of 25000 Lbs <> 111.2 KN and hydraulic power of 100 HP.

These features give a small but tough MM517-c drilling rig enough power to drill in any type of mixed hard formations. Please note that below specifications can be adapted to your needs on request (for example, same unit could be also be skid mounted).

Working temperatures: All our standard equipments are meant to operate CONSTANTLY at the temperatures various between - 45 to + 50 degrees Celsius (113 F to 122 F).
