Kaishan DTH Drilling Rigs
Heavy-duty surface crawlers and integrated rigs for open-pit mining, quarry blasting, and slope stabilization. High penetration rate and anti-jamming hydraulic system.
EQUIPMENT CATEGORIES
Integrates the down-the-hole drilling system and an onboard rotary screw compressor (12 m³/min @ 15 bar) into one unified crawler chassis. Powered by a single 162 kW Yuchai 6-cylinder diesel engine, eliminating the need to purchase, tow, and fuel a separate compressor while cutting diesel consumption by up to 30%.
Equipped with an onboard hydraulically driven cyclonic laminar flow dust extraction system. Captures rock dust directly at the hole collar to maintain clean operator visibility, protect engine filters, and comply with strict green quarry standards.
Built on a rugged engineering track frame with 430 mm ground clearance and dual-speed tramming motors (up to 4.0 km/h). Coupled with hydraulic frame levelling (Up to 10° / Down 9°), it manoeuvres with ease over rocky quarry obstacles and climbs 25° grades.
The versatile articulated boom and carriage feature 125° beam tilt, 94° carriage swing, and flexible boom elevation, providing extensive drilling coverage for vertical blast holes, inclined pre-splitting, and low-angle horizontal toe holes.

A: No. The KT5C is an integrated all-in-one rig. It carries an onboard high-pressure rotary screw air compressor (12 m³/min @ 15 bar) powered by the rig's own 162 kW Yuchai engine, operating as a fully autonomous single machine.
A: A split rig-and-compressor system requires two diesel engines, dual maintenance routines, and a dedicated towing vehicle. The KT5C uses one centralized engine, reducing diesel consumption by 25%–35%, lowering labor requirements to a single operator, and eliminating air line pressure drops over long distances.
