PRODUCT DESCRIPTION
Product Features
The JK930 all-in-one fully hydraulic open-pit Top Hammer Drill Rig is a flexible and versatile top hammer drill rig designed and developed for high-performance in demanding construction applications. It is also a highly efficient alternative for small to medium-sized quarries. Due to its low center of gravity and long boom reach, it maintains high utilization even in harsh terrain conditions. Equipped with a French Montabert rock drill and an efficient screw type air compressor from Atlas Copco, it is reliable and durable, with flexible operation, excellent drilling hole quality, and long service life, making it the ideal choice for various mining and engineering projects.
Main Advantages
Rock Drill
Equipped with the French Montabert HC150 rock drill with a 21KW impact power, the drilling efficiency is high, offering flexibility and efficiency. It features an adjustable impact frequency function, allowing for the frequency of the rock drill to be flexibly changed under different rock conditions to achieve high working efficiency. This reduces costs, making it highly effective in working across different rock formations.
Cabin
The ROPS and FOPS certified Cabin is comfortable and safe. The drill rod handling system is highly reliable, ensuring that drilling operations can proceed quickly and smoothly. The rig is designed for high efficiency and ease of maintenance, capable of performing all drilling tasks excellently.
Feed
The special pressed aluminum alloy feed beam is protected by a stainless steel wear-resistant sleeve, providing high strength and excellent straightness. The overall lightweight design of the feed results in low load and high reliability.
Folding Boom
The folding reinforced drill boom allows for multi-angle operations including horizontal, vertical, and inclined drilling, offering a large drilling coverage area suitable for various harsh terrains.
Air Compressor
Equipped with Swedish Atlas.Copco air compressor , it offers stable and reliable performance with low energy consumption.
Engine
The Cummins QSC8.3-C260-30 engine, with a powerful output of 194KW, offers strong and reliable performance with easy maintenance.
Automatic Rod Changing System
Equipped with 7 drill rod storages, drill rod specifications T45/T51*3660mm, automatic drill rod change operation is simple and easy to use, fast drill rod change speed and less auxiliary time, equipped with drill rod fall protection device
Air filter intake system
The three-stage air filtration system ensures clean intake air for the engine and compressor head. The first-stage air filter is an automatic back-flush filter, which is convenient and quick, eliminating the need for manual disassembly and cleaning. This system also prevents dust from entering the intake pathway due to manual operations, ensuring high reliability.
Undercarriage
Equipped with a maintenance-free four-track walking system designed specifically for construction machinery, with a ±10° body float angle. The angle of the body can be adjusted at any time during slope walking and operations to ensure the safety of both the operator and the machine. With a ground clearance of 455mm, it offers strong passability.
Feed Mechanism
The feed structure utilizes a motor and chain mechanism, ensuring rapid and efficient feed/lift speeds. It is equipped with an imported Eaton feed motor, offering reliable and stable performance.
