KT5D Integrated Down The Hole Drill Rig For Open Use

Jining Dongtai Lite Engineering Machinery Co., Ltd. is one of the leading manufacturers and suppliers of kt5d integrated down the hole drill rig for open use in China. With abundant experience, we warmly welcome you to buy customized kt5d integrated down the hole drill rig for open use made in China here from our factory. Good service and quality products are available.

The KT5D integrated down the hole drill rig for open use is an advanced drilling device integrating the down the hole drilling system and screw air compressor system, It is capable of drilling vertical, inclined and horizontal holes, mainly used for open-pit mine, stonework blast holes and pre-splitting holes. Equipped with the Yuchai Engine, drill pipe lubrication module and efficient dust collection system. It is typical of energy conservation, efficiency, safety, environment-friendliness, flexibility, simple operation and stable performance, etc.

Dual-Power Architecture: The KT5D Difference

• Independent power sources for drilling and compression: a dedicated primary engine drives the hydraulic drilling system (crawler, rotary head, feed, mast positioning), while a separate secondary engine powers the onboard compressor exclusively. Neither system competes with the other for power at any point in the operating cycle.
• Full compressor output at all times: because the compressor has its own dedicated engine, it delivers its full rated air pressure and volume regardless of whether the rig is simultaneously tramming, repositioning the mast, or performing rod changes - a critical advantage over single-engine designs where compressor output drops when other hydraulic loads are active.
• Higher air output than single-engine integrated rigs: the dedicated compressor engine enables a larger compressor unit to be fitted, delivering the air volume required to drive 5-inch to 6-inch DTH hammers at full performance - a capability beyond the reach of the KT5J and KT5C.
• Independent engine management: each engine can be started, stopped, and serviced independently, allowing the drilling system to remain operational during compressor maintenance intervals and vice versa, minimizing unplanned downtime.
   

Enclosed Operator Cabin

• ROPS/FOPS certified enclosed cabin with air conditioning, heating, and acoustic insulation, providing full operator protection and climate control across all operating environments.
• Positive-pressure filtered air supply to the cabin prevents dust ingress, protecting the operator from respirable dust exposure including respirable crystalline silica (RCS) in silica-rich rock formations.
• In-cabin digital instrument panel displaying real-time parameters for both the drilling system and the compressor: hole depth, rotation speed, feed pressure, compressor working pressure, compressor delivery, and both engine load and temperature readings - all from a single operator workstation.
• Ergonomic suspension seat with integrated joystick controls for all drilling, tramming, and mast positioning functions, designed for sustained single-operator use across extended shifts.
   

Drilling Performance

• Drill hole diameter range: 115 mm to 178 mm, covering mid-to-large blast-hole and production-hole specifications in open-pit mining and high-production quarry operations.
• Maximum drilling depth: up to 36 m per setup, suitable for high-bench configurations and large-scale production blasting programs.
• High-efficiency DTH hammer system with full-rated air supply from the dedicated compressor engine, delivering maximum penetration rates in hard rock formations up to 350 MPa UCS.
• High-torque rotary head with variable speed control, compatible with large-diameter DTH hammer sizes and drill rod configurations required for the KT5D's expanded hole diameter range.
• Hydraulic feed system with high feed force and pull-back capacity, enabling precise bit-to-rock contact pressure control across the full depth range and extending drill bit service life in abrasive formations.
• Mast angle adjustment supports vertical and inclined drilling up to 30 degrees from vertical for pre-split blasting, contour drilling, and angled production holes.
   

Mobility, Serviceability & Fleet Integration

• Heavy-duty crawler undercarriage with wide-gauge steel tracks, providing stable self-propelled mobility across quarry benches, uneven terrain, and loose ground surfaces.
• Centralized service layout with ground-level access to all daily maintenance points for both engines, the compressor, and the hydraulic system, keeping scheduled service time efficient despite the dual-engine configuration.
• Remote diagnostic port compatible with fleet management systems, enabling real-time monitoring of both engine and compressor health parameters for proactive maintenance scheduling.
• Optional dust suppression system (water mist or dry collector) for compliance with site dust emission requirements and improved hole cleanliness in sensitive environments.

• Mid-to-large open-pit mining: blast-hole drilling for iron ore, copper, gold, coal, and non-metallic minerals at operations requiring hole diameters above 152 mm and depths beyond the KT5J/KT5C envelope.
• High-production quarrying: large-diameter production drilling in granite, basalt, limestone, and sandstone quarries where output requirements demand the air volume of a high-capacity compressor in a single integrated machine.
• Sites with strict operator welfare requirements: operations where enclosed ROPS/FOPS cabin protection, climate control, and dust filtration are mandated alongside the need for larger hole diameters than the KT5C provides.
• Remote and access-restricted high-output sites: drilling programs where the logistical advantages of a single integrated machine are required at a production scale that exceeds the KT5J/KT5C capacity.
• Road, highway, and large civil infrastructure: rock cutting and slope stabilization drilling on major infrastructure projects requiring larger blast holes and higher daily meterage output.
• Hydropower and dam construction: foundation drilling and grouting-hole preparation in hard-rock environments where site access limits multi-unit deployments and larger hole diameters are specified.
