Explorer 90

Surface Diamond Core Drilling Rig


Explorer 90 Technical Characteristics

Explorer 90 is a complete hydraulically operated drill rig for coring and drilling underground galleries and surfaces that can be designed with an Electrical Motor or Diesel Engine. It is manufactured in three different frames: fixed skid, three wheel trailer, and tractor undercarriage. The rotation unit is hydraulically regulated and maintains a continuous speed between 440 -1250 (RPM). Explorer 90 offers the capability of swinging aside the rotation head for hole cleaning and grouting equipment access during operations. The top of the feeding frame comes with hydraulic jacks for stabilization. It has a unique automatic hydraulic system that synchronizes the performance between the chuck and rod holder. Explorer 90 has optional accessories such as larger wireline hoist, two step hydraulic waterpump and a gearbox to reach higher torque.
