For rock-drilling operations in mines, quarries and open-pit projects, crawler-mounted DTH drilling rigs are major equipment for hard-rock drilling. Both Xingda XDT integrated DTH drilling rig and XD crawler-mounted DTH drilling rig adopt crawler travelling design. Nevertheless, they differ greatly in product positioning, configuration and applicable working conditions. Customers can select optimal model according to site conditions, project scale and budget.

• Xingda XDT Integrated DTH Drilling Rig 

XDT is a highly-integrated all-in-one unit. It comes with built-in air compressor, no external air compressor required. Equipped with automatic rod changing mechanism, it largely reduces manual work for rod connection and disassembly and lowers labor intensity. Built-in dust collector and high-level automation deliver outstanding drilling performance.

Advantages: Highly integrated unit including air compressor, drilling assembly and dust suppression system. One single machine completes full drilling work. Automatic rod changer is ideal for deep-hole drilling. Convenient relocation, no extra trailer or complicated air-pipe layout, saving cost for auxiliary equipment and transportation.

Application: Medium-large open-pit mines and large-scale quarries, projects with deep-hole requirement, heavy workload and high demand for automation to cut auxiliary equipment investment.

• Xingda XD Crawler-Mounted DTH Drilling Rig 

XD crawler DTH rig serves as standalone drilling unit which requires external air compressor for air supply. It features powerful rock-drilling capacity, flexible crawler movement, multi-angle adjustable mast and integrated dust collector with proven and reliable structure.

Advantages: Lower initial cost for main unit. One air compressor can serve multiple rigs. Lighter weight for flexible relocation. Simple maintenance and high spare-part compatibility.

Application: Small-medium quarries, slope stabilization, subgrade blasting projects for medium-shallow holes. Suitable for sites with existing air compressor or limited budget, where one compressor supports several rigs simultaneously.

• Key Differences Summary

1. Air source: XDT has built-in air compressor for independent operation; XD needs external air compressor.
2. Rod handling: XDT is fitted with automatic rod changer, better for deep-hole drilling; XD uses manual rod handling.
3. Cost: XDT has higher complete-unit cost while saving air-compressor investment; XD main unit costs less, but separate air compressor is mandatory.
4. Drilling depth: XDT excels in deep-hole jobs; XD fits medium-shallow blasting and anchor-hole drilling.

Xingda Machinery provides customized one-on-one solution including model selection and complete drilling-tool packages based on rock hardness, target hole depth, site environment, existing equipment and budget. Technical guidance, spare-parts supply and remote after-sales support are available to help customers improve working efficiency and control overall project cost.
