Product Overview
The HY450T truck‑mounted water well drilling rig is a high‑performance integrated all‑in‑one drilling solution mounted on a heavy‑duty truck chassis. It delivers a maximum drilling depth of 450 m and supports 6 m drill rod operation. Unlike trailer‑towed and crawler drilling rigs, this fully self‑propelled truck‑mounted design needs no trailer transportation or crane assistance. Therefore, it realizes arrive‑and‑drill operation, greatly improving construction efficiency and on‑site flexibility.
Furthermore, the unit adopts a full hydraulic top‑drive system and supports dual drilling modes: pneumatic DTH drilling for hard rock and mud circulation drilling for soil layers. Meanwhile, it adapts to various complex formations such as soil, sand, gravel and hard rock. Besides, it fits frequent site‑transfer projects, rural water well construction, agricultural irrigation, geothermal wells and diverse urban‑rural drilling assignments.
Equipped with well‑known brand core hydraulic components and a high‑strength steel frame, the HY450T features stable operation, low failure rate and excellent durability. For long‑term engineering operations, it delivers outstanding comprehensive cost‑performance.
Key Features
The self-propelled truck chassis supports fast road travel and cross-region transfers. No equipment disassembly, trailer towing or crane loading is required, effectively reducing transportation and transition costs.
Rotary speed, torque, thrust pressure and lifting speed support stepless real-time adjustment, matching different drill bits, drill rods and diverse construction processes.
It is compatible with pneumatic DTH hard rock drilling and mud circulation soil drilling. Optional configurations including mud pumps, foam pumps and generators can be equipped to meet diverse on-site drilling requirements.
The top-drive rotary propulsion and lifting system shortens auxiliary pipe connection time. Mature DTH rock drilling technology ensures fast drilling speed and effectively reduces per-meter drilling costs.
Multiple hydraulic outriggers provide strong and stable support during deep drilling operations. The adjustable positive and negative axial pressure system ensures the impactor always works at optimal efficiency.
All core hydraulic systems and key components adopt renowned brand parts. The main frame is made of high-strength alloy steel, delivering excellent structural strength, wear resistance and long service life.

Applications
Thanks to its strong mobility and multi‑formation drilling capacity, the HY450T truck‑mounted well drill rig covers a wide scope of field projects. In particular, it is ideal for rural drinking‑water well drilling and farmland irrigation well development. In addition, it works perfectly for geothermal hole drilling, water resource exploration, municipal water‑supply projects and temporary water‑supply jobs for mining sites. Above all, fast relocation makes it highly preferred for contractors who frequently move between different construction sites.
