Features

Four stabilizer legs with independent hydraulic control ensures the high stability during drilling operations;
Hydraulic feed cylinders with direct force applied to ensure the smooth feed and high drilling accuracy;
Once it is setup, the hydraulic long hole drilling rig can drill parallel holes with a maximum width of 3052mm, greatly increasing the efficiency and accuracy of drilling works in worksites; The maximum width of the extraction face is 7942mm, and the maximum height is 4925mm;
The DTH drilling rig has 360-degree rotation function and hydraulic rotary table, enabling it to conquer underground confined spaces;
All key hydraulic components, electrical components, remote control unit and control buttons are from world's renowned brands to ensure the reliable performance under extreme working conditions;
Diesel engine makes the drilling rig able to perform walking and drilling operations in the underground working spaces in the absence of power source;
The operation of DTH drilling rig is carried out on the vehicle, thus securing operator's safety and giving a good visibility; The protective roof is equipped to guarantee that the operator is protected from roof falls;
Hydraulic pilot joystick control makes drilling operation easier;
Less hydraulic hoses applied in the drilling rig result in lower hydraulic losses and higher energy efficiency;
Hydraulic drive cable reel allows for installing cable of 80 meters in length;
Drill rod thread protection function helps reduce drill rod thread wear, thus significantly prolonging the service life of the drill rod;
One-key open hole drilling function enables the hydraulic long hole drilling rig to automatically lower the feed force, impact pressure and frequency, therefore increasing the drilling efficiency and hole straightness;
Anti-jamming system improves the drilling rig's adaptability to various difficulties in drilling operation;
The DTH drilling rig is equipped with hydraulic guiding system to ensure the hole straightness;
Cable remote control allows operator to perform driving and drilling far away from dangerous areas where rock falls;
Down the hole drilling rig has a hydraulic wet dust removal system with adjustable water volume and water pressure, and water pressure alarm function. The rig also has tilt sensor, and color LCD display screen, capable of accommodating drilling rods required for a 30-meter drilling depth.
The main valve integrates the functions of walking, rotating, advancing, and speed selection.
The drilling rig is equipped with a double-layer hydraulic clamp and rod discharging mechanism, the operation of rod discharging is simple and efficient, reducing manual involvement.
Automatic anti-jamming function improves the adaptability to complex rock formations, maximizing prevention of jamming accidents.
