Working Principle
The Kaishan KG430 operates on the Down-The-Hole (DTH) drilling principle, where a pneumatic hammer is integrated into the drill string just above the bit. High-pressure air is delivered through the drill pipes to the hammer, driving the piston to strike the bit at high frequency. The bit crushes rock into small fragments, which are then flushed out of the hole by the exhaust air. Simultaneously, the rig's rotary head applies rotation and feed force to the drill string, ensuring even bit wear and straight hole trajectory. The hydraulic system powers the rotation, feed, and tramming functions, while the diesel engine drives the air compressor and hydraulic pumps. This combination allows the KG430 to achieve high penetration rates in hard rock with minimal energy loss. The operator controls all functions from the ergonomic cabin, monitoring drilling parameters via the control panel. The dust collector captures airborne particles, maintaining a safe and clean working environment. This efficient and proven method makes the KG430 a reliable choice for demanding drilling applications.

Frequently Asked Questions
What hole sizes and drilling depth can the Kaishan KG430 handle?+
The KG430 drills hole diameters from 90 mm to 165 mm and reaches a drilling depth of 30 m. It uses the DTH (Down-The-Hole) drilling method for hard-rock work. This range covers blast hole drilling and other production holes in open-pit mining and quarrying.
What engine powers the KG430 DTH drilling rig?+
The KG430 is powered by a 73 kW diesel engine. The rig weighs 5,250 / 5,700 kg and measures 8,500 × 2,500 × 3,200 mm (L×W×H). The engine drives the hydraulic system and the high-torque rotary head with automatic rod handling.
What air supply does the KG430 need to run a DTH hammer?+
The KG430 is a DTH drilling rig that runs a down-the-hole hammer, so it requires a matching air compressor to supply the working pressure and free air delivery for the hammer and button bit. The required air supply depends on the hammer and bit selected for the 90–165 mm hole diameter range. The rig itself is powered by its own 73 kW diesel engine.
Where can the KG430 be used?+
The KG430 is built for open-pit mining, quarrying and aggregate production, construction and foundation work, and water well drilling. Its heavy-duty crawler chassis provides stability and mobility on rough terrain, and the DTH method handles hard rock such as granite, limestone, and basalt. The 30 m drilling depth and 90–165 mm hole diameter suit blast hole and foundation drilling.
How is the Kaishan KG430 shipped?+
The KG430 is shipped in a disassembled state for efficient container transport, with main components packed and protected against corrosion and impact. Typically, one 40HQ container can accommodate the rig with proper loading. Delivery time is 30–45 days after order confirmation, depending on configuration, and shipping ports include Shanghai, Qingdao, or other major Chinese ports.
What warranty and after-sales support come with the KG430?+
The KG430 comes with a 12-month warranty or 2000 working hours, whichever comes first, covering major components. A 24-hour technical support hotline is available for troubleshooting, along with on-site installation and commissioning guidance and operator training. Genuine spare parts are available through the global distribution network.
What maintenance features does the KG430 offer?+
