The KZZD crawler-mounted excavator conversion DTH drill is a specialized anchoring device designed for slope support engineering, mainly used in the soil nailing field. It performs excellently in projects involving anchor rods, cables, anchor holes, and steel pipe piles. The drilling efficiency can reach depths of 400-600 meters, showcasing the high performance of this efficient anchoring drill.

Quzhou Kaizuan Machinery, building on mature technology, continuously improves the production capacity and operational adaptability of its drilling rigs. The down-the-hole (DTH) drilling rig offers higher productivity, greater adaptability, and better hole-forming quality in terms of application flexibility and reliability. A single drilling rig can be relied upon for production drilling, accelerating stripping speed through parallel sectioning and pre-split drilling while controlling dilution rates. With its lighter weight and compact size, the KZ910B model is extremely convenient for transfers between worksites and benches due to its excellent flexibility and powerful operational capabilities.

​The down-the-hole (DTH) drilling rig comes in two types: internal combustion and electric, and it is a device used for drilling holes in rock. The DTH drill stands out due to its distinctive features, and based on different characteristics, it can be classified into various types. The application areas of different types of DTH drilling rigs also vary. Below is a brief introduction to the classification, uses, and characteristics of DTH drilling rigs:

The prominent advantages of the drilling rig are: Stable movement and safe operation. Since the ground contact dimensions are not limited by the chassis and the counterweight is reasonably distributed, there is no risk of lateral tipping accidents. High verticality in pile formation. The column is supported at three points with dual-directional adjustments, making the drilling verticality far superior to that of suspended crawler pile frames. Beneficial to urban construction and environmental protection. It uses an electric motor drive, producing low noise and avoiding disturbance to residents; it does not burn diesel, emits no exhaust gases, and protects the environment. Simple maintenance. The failure rate and maintenance costs of an electric motor are far lower than those of diesel engines and hydraulic drive systems. Flexible and rapid movement with high construction efficiency. It avoids the common issue of step-type pile frames struggling to move due to leg subsidence. Construction efficiency can be improved by 2-3 times, with no blind spots in pile positioning.

The full hydraulic drilling rig is highly suitable for use in soil layers and rock layers, including complex formations such as gravel and cemented gravel layers. It is widely used in foundation engineering construction for building projects, farmland projects, and bridge projects. This equipment is ideal for deep foundation construction in large diameter projects.

Drilling machinery is divided into rock drills and drilling rigs, with drilling rigs further categorized into open-pit and underground types.
