Description

JK820 Crawler DTH Drilling Rig — Built for Quarry and Mining

The JK820 is a crawler-mounted down-the-hole (DTH) drilling rig designed for medium to hard rock formations. It covers a hole diameter range of 90mm to 138mm with economical drilling depth of 20m and a maximum reach of 30m. Powered by a reliable diesel engine and a fully hydraulic system built with domestic first-tier brand pumps and multi-way valves, this rig is engineered to perform shift after shift with minimal downtime.

Key Performance Highlights
