6 FAQs about [Down-the-hole drill rig manual electronic version]
What is a drill rig safety manual?
It emphasizes the importance of reading the safety information and following the instructions in the manual to properly operate and maintain the drill rig.
What is a drill rig specification?
It provides technical specifications for the drill rig, including its general description, field of application, basic machine components like the propulsion unit and hydraulic system, the mast, rotary head, clamps, winch, and instructions for stabilizing the machine.
What to do if a drill rig is lost?
If the labels or manual are lost, you can contact the dealer and indicate the model of drill rig to purchase. Only trained and qualified operators are permitted to operate this drill rig. Keep the drill rig in good condition as per this manual.
How do you use a DTH drill?
Thrust should be kept as low as possible at all times to avoid excessive vibration in the drill string. Hold back should be increased more and more as additional rods are added and as drilling progresses. DTH drilling is primarily percussive drilling using the energy imparted by the hammer piston to the rock through the bit.
How much hold back should be increased in DTH drilling?
Hold back should be increased more and more as additional rods are added and as drilling progresses. DTH drilling is primarily percussive drilling using the energy imparted by the hammer piston to the rock through the bit. Any attempts to apply too much weight could damage the bit, hammer and drill string and impair the drilling rate.
How do drill rigs work?
Conventional drilling rigs use the power of an electric motor or a diesel engine, which is transmitted to the turntable through the operating system to drive the drill bit connected to the drill rod to grind and cut the rock to achieve the purpose of drilling. This kind of drill first solves the ground power.
