GENERAL SPECIFICATIONS

The Derrick

The derrick is fabricated from hollow drawn steel tube and hot rolled sections. The feed cylinder has a 6,5 metre stroke and is coupled to an inner derrick which carries the rotary head.

Rotary Head etc

The rotary head consists of a single high torque rotary motor coupled to an air-mud swivel with extra heavy duty bearings which take all forces produced during drilling operations. The bull shaft on the air swivel has a 4,5" Full hole thread to which the drill string is attached. A built-in shock absorber on the head minimizes vibration and shock loads to the machine and drill string. A hydraulic 2 speed system is fitted as a standard to all machines. The rotary head is fitted to an inner derrick which runs inside the outer derrick on 6 heavy duty tyres which almost eliminates all wear.

Hydraulic Outriggers

Four hydraulic outriggers are fitted to the outer corners of the rig for easy and accurate leveling of the rig.

Hydraulic Cylinders

Twin hydraulic cylinders are used to raise and lower the derrick and to lock it in for angle drilling operations.

Control Panel

All hydraulic controls are fitted into a single panel in front of the operator making the operation of the machine very easy and simple even for unskilled operators. A finger tip down feed valve is fitted to ensure even pressures during drilling operations.

Working Table

The working table is fitted with removable half ring guide collar locks, which when removed, allows 600mm diameter tools or augers to pass through. Guide bushes are supplied to suit the drill string.

Power Pack

The power pack consists of a 6 cylinder turbocharged Deutz diesel engine, close coupled to a 3 stage positive displacement gear pump. All necessary air, fuel and oil filters and coolers are fitted.

Tools

Keeper keys and rod handling tools are supplied to suit the drill string.

Break Out Cylinder

A breakout hydraulic cylinder is fitted to facilitate the breaking of hammers and drill rods.

Lubrication

A 10 litre in line oil lubricator for DTH hammers is fitted as standard.
