Features

1. The drilling jumbo adopted a direct controlled drilling system which incorporates excellent anti-jamming function RPCF (Rotation Pressure Controlled Feed force). Separate pumps for percussion/positioning, rotation for independent control and maximum output.
2. HC109 hydraulic drifter with large flow, low pressure and modern double reflex dampening giving genuine high speed drilling and excellent drill steel economy. New lubrication system keeps all contacting surfaces with reliable operation, low maintenance cost and long intervals between overhauls.
3. HT series heavy-duty box-type hydraulic feeds with high torsional resistance, and n type feed is suitable for any angle of holes with a longer life and low maintenance cost.
4. Telescopic heavy-duty booms for direct, fast and accurate positioning between holes. All boom joints are using improved expansible shaft structure.
5. Sturdy, articulated carrier with four wheel drive for easy manoeuvring in narrow tunnels and drifts. Power steering, hydraulic release brakes and central lubricated chassis are adopted. Four jacks for stable set up.
6. Basic rig includes telescopic FOPS-approved protective roof, cable reel, work lights(2x70W halogen), water booster pump and pump unloading function for easier start with low voltage.
