Crawler Mounted DTH Drilling Rig Manufacturer
JK Drilling manufactures crawler mounted hydraulic DTH drilling rigs for surface drilling projects. The range includes models for blast holes in open-pit mines and quarries, as well as equipment for road construction and other rock drilling work. Buyers can compare hole diameter, drilling depth, air requirements, rod handling and site access before selecting a rig.
A suitable DTH drilling setup depends on more than the rig alone. The hammer, drill bit, rods and compressed air supply must also match the required hole and ground conditions.
Find the Right Crawler Mounted DTH Drilling Rig
Start with the holes you need to drill. Diameter and depth narrow the model range; application, rod handling and site conditions help determine the final configuration. JK Drilling offers several crawler mounted rigs with different drilling capacities and operating arrangements.

Choose a Rig for Your Drilling Application
Open-Pit Mining and Quarry Blast Holes
For production blast holes, provide the required hole diameter, bench height, target hole depth and rock conditions. These details help narrow the model choice and identify the air supply and drilling tools needed for the proposed hole size. The JK610 is presented by JK as a blasting borehole rig, while the JK593G is described for larger blast holes and photovoltaic holes.
Road Construction and Rock Excavation
Road cuts and other surface construction sites may require frequent repositioning or drilling at different angles. Check the machine’s transport dimensions, weight, travel conditions and required drilling orientation against the actual site before ordering. JK publishes model-specific travel and gradeability figures on its product pages; the final selection should use the figures for the model being quoted.
Large-Diameter Photovoltaic and Infrastructure Holes
JK describes the JK593G as a rig for blast holes and photovoltaic holes and publishes a 90–300 mm borehole diameter range. If this is your application, send the required diameter and depth so the corresponding drill string, air supply and operating setup can be checked together.
Split-Type Rig or Integrated DTH Rig?
A key purchasing question is how compressed air will be supplied to the DTH hammer. When comparing rigs, check whether the compressor is built into the machine or must be supplied separately. This affects the equipment list, transport plan and total quoted package.
JK offers a separate range of integrated hydraulic DTH drilling rigs. For example, its JK830 integrated DTH automatic drilling rig is described with a built-in compressor. Buyers considering both arrangements can request a comparison based on their required hole size, site logistics and available air equipment.
Before accepting a quotation, ask: Is the air compressor included? If it is separate, what operating pressure and air delivery are required for the proposed hammer and hole diameter? Which hoses, hammer, bits and rods are included?
Check the Complete Drilling Configuration
Hole Diameter, Depth and Rock Conditions
The proposed rig must cover the required hole diameter and depth under the project’s ground conditions. Give JK the rock description or hardness information available from your site, together with the drilling plan. Confirm whether the quoted depth is the machine’s drilling capability, the depth supported by its rod handling system, or the length of a supplied drill string.
Compressor, Hammer, Rods and Bits
A DTH rig is only one part of the drilling system. Ask for a configuration list showing the proposed air compressor, percussive hammer, drill rods and drill bits. If you already own a compressor, provide its pressure and air delivery so compatibility can be assessed before an order is placed.
Rod Handling and Dust Control
Rod handling affects the amount of manual work required during drilling. JK lists an auxiliary rod changer for the JK595-5A and automatic rod changing for the JK730-2. Dust control also varies by model and configuration. Confirm whether the quoted machine includes a dry dust collector or whether a wet system is required for the site.
Transport and Site Access
Send the available access width, slope conditions and any transport limits. The selected model’s published dimensions, weight and gradeability should be checked against those limits. A larger hole range or more automation may change the machine size and the support equipment needed on site.
Why Source Your DTH Rig from JK Drilling?
JK Drilling identifies itself as Zhangjiakou Xuanhua Jinke Drilling Machinery Co., Ltd., a developer and manufacturer of DTH drilling equipment. Its published range includes crawler mounted rock drilling rigs, integrated DTH rigs and well drilling rigs. Buyers can review the company introduction, certificates, project cases and services and support when assessing the supplier.
For a relevant project reference, JK also publishes a JK730 case in DR Congo. If you need evidence for a particular application, ask for a case involving a comparable model, hole size and working condition.
What to Confirm Before Placing an Order
A useful quotation should make the equipment scope clear enough to compare suppliers on the same basis. Ask JK to identify the exact model and configuration, then confirm the following items in writing:
Required hole diameter and depth, and the conditions used for model selection.
Whether the compressor is built in, supplied separately or excluded.
Hammer, bits, rods, hoses and dust control included in the price.
Standard and optional features, including rod handling and operator controls.
Machine dimensions and weight for transport and site access.
Lead time, delivery terms, commissioning arrangements, spare parts and warranty terms.
If you are comparing quotations, compare the complete operating package, rather than the rig price alone.
Frequently Asked Questions
What is the difference between a crawler mounted DTH rig and an integrated DTH rig?
The distinction to check is the air supply arrangement. An integrated model carries its compressor on the machine; a rig that uses a separate compressor needs the two pieces of equipment to be matched for the proposed drilling task. JK offers both product ranges. Confirm the arrangement for the specific model in your quotation.
Which JK model should I choose for blast hole drilling?
Begin with the planned hole diameter and depth. JK lists the JK593G for larger blast holes, the JK610 for blasting boreholes, and models with different rod handling arrangements in the same category. Send the drilling plan and site conditions to narrow the choice.
Does the JK730-2 drill only 18 m or 21 m deep?
JK labels 18 m / 21 m as “auto rod-changing depth” on the JK730-2 model page. The buyer should request separate confirmation of maximum drilling depth for the proposed configuration.
What is the maximum drilling depth of this product range?
There is no single verified maximum that should be applied to every model on this category page. For example, JK publishes 50 m for the JK610, while the JK593G page does not publish a maximum depth. Confirm the limit for the exact model and drilling setup being purchased.
Is an air compressor included with the rig?
Confirm this in the model-specific quotation. Provide your existing compressor’s operating pressure and air delivery if you plan to use it with the new rig. JK also has a separate air compressor range.
Can these rigs drill water wells or geothermal wells?
The suitability depends on the required well diameter, depth and ground conditions. JK has a dedicated crawler mounted well drilling rig range for buyers seeking deeper well equipment. Ask JK to recommend the appropriate range from your project requirements.
Can I order drilling tools and spare parts with the machine?
JK lists drill rods, percussive hammers, drill bits and other rig parts on its website. Request an itemized quotation to confirm compatibility, quantities and what is included.
