INTEGRATED DOWN THE HOLE DRILL RIGS
Down-the-hole drill rigs in the 1990s
A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill hard rock. The system is thought to have been invented independently by Stenuick. Origin of the nameDTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanis. . In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the flui. [pdf]
Integrated vehicle-mounted screw air compressor model
Above-deck rotary screw air compressors can easily mount onto a service truck, skid, or trailer. These systems are securely bolted into place and then ready to use. These are the mobile air compressors that most people are familiar with because they are highly visible on many service vehicles. Above-deck. . Vehicle integrated air compressors are innovative solutions that are mounted in the truck’s engine compartment or under the deck. Operators love these systems because they don’t. . Deciding on the right truck mounted air compressor for your vehicle can be overwhelming. Many choices come down to preference,. [pdf]FAQS about Integrated vehicle-mounted screw air compressor model
