Ingersoll rand drilling rigs

Types of Ingersoll Rand drilling rigs

Depending on the mining method, several kinds of Ingersoll Rand drilling rigs are available.

• Top Hammer Drilling Rigs

  Ingersoll Rand top-hammer drilling rigs strike the rock from the top. They are typically utilized for open-pit mines, quarries, and infrastructure projects. Their benefits include adaptability to various rock situations, effectiveness in penetrating softer to moderately hard rock, and the capacity to use various drill bits for different applications.

• Down-the-Hole (DTH) Hammer Drilling Rigs

  Ingersoll Rand DTH drilling rigs adopt a hammer-perc action method, where the hammer is located directly over the drill bit in the hole. This positions the blow directly on the bit for effective drilling. DTH rigs suit open-pit mines, quarries, and blasting holes. They excel in penetrating hard and dense rock formations. Their advantages are the effective pressure transmission from the drill string to the DTH hammer and bit, high-impact energy generation, and improved drilling precision and control.

• Rotary Drilling Rigs

  Ingersoll Rand rotary drilling rigs adopt the rotary method to excavate rock. They suit various locations, such as open-pit mines, quarries, oil and gas extraction, and water well sinking. They are good choices for operations requiring precise control over hole diameter and depth. Their advantages include high-speed drilling, the capacity to penetrate various kinds of rock with several drill bit styles, and improved hole quality and accuracy.

• Top Hammer Crawler Drilling Rig

  Ingersoll Rand top hammer crawler drilling rigs adopt a crawler method for rock drilling. They usually suit open-pit mining, quarrying, and infrastructure development. Their advantages include mobility and adaptability to various topography. They are good choices for hole excavation in an open-pit mine and rock blasting in a quarry.

Maintenance

Routine inspection, monitoring, and maintenance. Rig operators should also establish a preventive maintenance plan based on the manufacturer's guidelines. Proper training of personnel on safe operating practices and maintenance procedures is essential to prolonging the life of the drilling rig and ensuring safety during its use. Here are some general maintenance tips:

• Cleaning: Clean the exterior of the rig and its components to remove dirt and debris. Pay special attention to the cooling system where impurities can affect the radiator and fan. Use air blowers to dry water from electrical parts.
• Inspection: Conduct periodic inspections of critical components like bearings, seals, gears, drill pipes, bits, etc. To identify signs of wear or damage that may require repair or replacement.
• Lubrication: Lubricate the moving parts according to the specified grease and oil. This helps reduce friction and prolong the life of the components.
• Replacement: Replace drill bits, pipes, hoses, sealing elements, etc., once they get worn out or damaged beyond repair to maintain accuracy in drilling operations.
• Electrical check: Regularly inspect electrical wiring and connections for loose or damaged areas so as not to cause a short circuit while driving the machine.
• Hydraulic System: Check hydraulic oil level, quality, and seals periodically. Clean the oil tank if necessary, and replace it with new oil when specified. Avoid cross-contamination of different fluids.
• Gearboxes: Check the oil seals and replace the gear oil if it is dirty or has reached the end of its service life as per the manufacturer's maintenance schedule.

Scenarios in which Ingersoll Rand drilling rigs are used

• Mining industry
