Functions and Features

Main Components

To achieve higher working efficiency in drilling operations, we used the Malta automatic rod handling system on the JC660 to improve drilling quality and safety while reducing labor costs and physical effort.
Equipped with imported high-torque travel motors, it can tow an air compressor freely. The support wheels are maintenance-free, and the track plates have mud-discharge grooves, reducing the chance of jamming.

The JC660 uses a customized BSC two-stage screw energy-saving main unit with an output of 16 m³/min and a pressure of 1.8 MPa, offering high compression efficiency, fast operation, and low energy consumption.
The adjustable dust hood can move up and down, facilitating the removal of rock debris near the drilling hole and allowing observation of the drilling process.

Features Introduction

Product Description

The JC660 Integrated Hydraulic DTH Drilling Rig is engineered for efficient hard rock drilling in quarrying, mining, and infrastructure projects. Powered by a 191 kW Yuchai turbocharged engine and a BSC two-stage energy-saving screw air compressor, it delivers stable airflow at 16 m³/min and 1.8 MPa, ensuring reliable penetration for φ90–130 mm holes up to 60 meters deep.
Featuring an automatic Malta rod handling system, Eaton high-torque motors, reinforced slewing reducer, and an integrated control console, the JC660 provides smooth, safe, and highly efficient drilling operations. Its vertical direct-drive layout, automatic air filter cleaning, and compact crawler-mounted design minimize maintenance, reduce power loss, and enhance operational reliability in harsh field environments.

High-Efficiency Power and Air System

Equipped with a 191 kW Yuchai engine and a BSC two-stage screw air compressor, the JC660 delivers stable airflow (16 m³/min, 1.8 MPa), energy-saving operation, and reliable drilling performance for hard rock conditions.

Advanced Rod Handling and Hydraulic Control

The Malta automatic rod handling system, Eaton high-torque motors, and integrated hydraulic control console enable fast, safe, and efficient drilling up to 18 m, reducing labor intensity and improving overall operational productivity.
