Before drilling, inspect the condition and lubrication of all drill string components, including the hammer or drifter. Replace any worn out parts, following manufacturer’s recommended discard limits closely. Snake skin is a wear pattern of micro cracks that develop from drilling fatigue in non-abrasive rock..
This chapter contains some common types of failures occurring on DTH drilling tools For most failures we can identify it’s probable cause and typical supporting evidence.
Rod connection and removal are crucial aspects of down-the-hole drill operations, directly impacting overall work efficiency and the service life of rock drilling tools..
It was possible that the rig was drilling in severe drilling conditions, or that the driller was pushing too hard or had a poor drill string design. I asked some questions as to hole sizes, depths, etc.

For the land rig market, we provide horizontal and vertical pipe handling with our series of PipeCat catwalk machines and the stand transfer vehicle (STV). Catwalk machines are designed to deliver tubulars to the drill floor, and the STV racks tubulars between the fingerboard area and well center. Both tools are. .
Parallel-column pipe-racking systems represent the next generation of automated pipe-racking systems. These machines provide the most flexible pipe racking configurations and capacities in the industry and can be integrated into new builds or. .
Our family of pipe-handling systems consists of several options, varying from simple belt conveyors to semiautomatic pipe-handling cranes. We offer the safest and most efficient. .
The main function of the pipe-handling crane is to transport tubulars between the pipe deck and the catwalk using a purpose-built pipe gripper yoke. The crane may also be used for other lift operations such as moving bulk equipment and containers, either by. .
Our horizontal-to-vertical (HTV) machines are designed to deliver singles from the catwalk position to the vertical position above a mousehole for stand-building operations. Once a.
