Import Down The Hole Drill Rig — Buy in Bulk from Supplier in China

The Down the hole drill rig offered by Zhengzhou Dayu Drill Rig Machinery Co., Ltd. is a hydraulic rock‑drill system designed for water‑well and borehole applications. It features a propulsion mechanism where thrust force increases while rotary speed remains constant, allowing the rig to maintain optimal puncture speed. The machine can deliver a maximum rotary torque that matches the peak demand of rock‑drilling cycles. The design separates the impact mechanism from the rotary system to improve torque stability.

In the drilling industry, similar rigs are typically powered by hydraulic units rated around 150 kW and operate at pressures near 30 bar. Standard pipe diameters for such rigs range from 4 in to 6 in, and the hydraulic circuit is configured for a propulsion force of 10‑30 kN. The rig’s mobile configurations include truck‑mounted and crawler‑based platforms, providing flexibility on uneven sites. These typical parameters ensure compatibility with common well‑bore standards and reduce auxiliary equipment needs.

The primary customers are water‑well contractors, mining service firms and infrastructure developers requiring reliable borehole creation. Buyers should confirm the minimum order quantity, price quotation and chosen Incoterm directly with the supplier before placing an order. Delivery is usually coordinated from Zhengzhou, with options for containerised shipment to major ports. Payment terms and lead‑time details are not disclosed in the listing and must be agreed with the seller.
