The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit. The hammer strikes the bit with considerable force, fracturing the rock immediately beneath it. As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.

  • Due to the machine's working environment being prone to intense vibrations and impacts, constantly observe the dynamics of various parts during operation. If you detect abnormal noise or other irregularities, shut down the machine immediately for inspection and repair before resuming operation. If hydraulic system connectors leak or components become loose, shut down the machine for adjustment and tightening. After ensuring everything is normal, you can resume operation. Before completing each shift, lower the hydraulic hammer to the lowest position and retract all other hydraulic cylinders to their shortest length. If moving a distance, keep the mast leaning backward. For the machine's components, accessories, and electrical equipment, perform regular inspections, especially the connections in the wiring of the motor. During operation, there should be designated personnel for guidance. The guide and the operator should check signals with each other before work and cooperate closely. At the start, use a bell or other methods to signal and inform surrounding personnel to move away. The machine should start at a low speed and gradually accelerate to high speed.
