Product Introduction 01
The HFTQ4C Automatic Rod Changing Integrated Down-The-Hole (DTH) Drilling Rig is a next-generation drilling solution developed by Hanfa Group for open-pit mining, quarrying, road construction, hydropower projects, and large-scale blasting operations. Combining an integrated air compression system with an advanced automatic rod changing mechanism, the HFTQ4C significantly improves drilling efficiency while reducing labor requirements and operational risks.
This rig adopts robust heavy-load steel frames processed by precise digital cutting and automated robot welding, supporting stable long-term operation under severe field conditions. Vulnerable wearing parts are forged from high-grade alloy raw materials with professional thermal processing, extending service lifespan and lowering daily servicing spending.
Its automated pipe exchange unit completes pipe replacement swiftly and safely without manual assistance, cutting idle periods and boosting overall work throughput. Outfitted with high-twist hydraulic rotating assemblies and smart hydraulic control modules, the machine achieves rapid rock penetration and accurate bore positioning when drilling medium-hard and hard rock layers.
Product Introduction 02
The integrated design combines the drilling rig and air compressor into one compact unit, improving mobility, reducing transportation costs, and simplifying jobsite setup. Manufactured under strict quality management standards and utilizing internationally recognized hydraulic components, the HFTQ4C offers reliable performance, lower operating costs, and long-term operational value.
Ideal for mining contractors and construction companies, the HFTQ4C delivers a highly efficient and automated drilling solution for modern surface drilling applications.
Product Characteristic
Using its single power to drive the screw air compressor and the hydraulic system of the drilling rig at the same time, compared with the split drilling rig, the comprehensive fuel consumption is 35% energy saving, and the maintenance cost is reduced by 50% The core hydraulic components are imported from Europe. The reliable hydraulic system greatly reduces the workload of system maintenance and is convenient and practical Powerful two-speed hydraulic walking mechanism, strong off-road capability, high-torque slewing motor can easily deal with stuck pipe The two-stage dry dust collector is environmentally friendly and also helps to improve production efficiency; integrated technology solves the problems of engineering and mine air compressor movement and remote management.Technical Data
