Main Components
- Hydraulic drifter
- Diesel engine
- Track undercarriage
- Boom and feed beam
- Automatic rod changer
- Operator cabin
- Dust collection system
- Control panel
Working Principle
The Kaishan KT7C operates on the top hammer drilling principle, where a hydraulic drifter generates high-frequency percussive impacts on the drill string. The impact energy travels through the drill rods to the drill bit, which crushes the rock. Simultaneously, the drifter rotates the drill string, allowing the bit to index between impacts. Compressed air is used to flush cuttings out of the hole, ensuring a clean hole and efficient drilling. The rig's hydraulic system controls the feed force, rotation speed, and percussion pressure, optimizing drilling parameters for different rock types. The track undercarriage provides mobility, while the boom and feed beam allow precise positioning of the hole. The operator controls all functions from the ergonomic cabin, monitoring drilling parameters via a digital display. This system ensures high penetration rates, straight holes, and long bit life, making the KT7C a reliable choice for surface drilling.

Frequently Asked Questions
What hole diameter and drilling depth does the KT7C cover?+
The KT7C drills hole diameters from 76 to 115 mm to a drilling depth of up to 30 m. It is a top hammer drilling rig built for blasthole work. The 15,000 kg operating weight supports stability at these diameters.
What engine powers the Kaishan KT7C?+
The KT7C runs on a 194 kW diesel engine. That power feeds the hydraulic system and the high-performance hydraulic drifter for penetration. The engine is described as fuel-efficient for the rig class.
What equipment matches the KT7C in a drilling spread?+
The KT7C is a top hammer drilling rig, so it works with top hammer tooling rather than a DTH hammer. Its hole range of 76 to 115 mm and 30 m drilling depth define the consumables it accepts. Match bits and rods to that diameter and depth window.
Where can the KT7C be used?+
The KT7C suits open-pit mining, quarrying, construction and road construction. Its track-mounted undercarriage gives mobility on rough terrain, and the articulated boom positions holes precisely. A dust suppression system and ergonomic cabin support work on site.
How is the KT7C maintained?+
The KT7C uses a modular design for easy maintenance, with regular maintenance kits and genuine spare parts available. An automatic rod changer reduces downtime in the drilling cycle. Kaishan's global service network provides 24-hour technical support.
What warranty and support come with the KT7C?+
The KT7C carries a 12-month warranty or 2000 working hours, whichever comes first. Kaishan provides on-site installation, commissioning and operator training. The global service network supplies prompt spare parts delivery.
How is the KT7C shipped?+
The KT7C ships disassembled for efficient transport, with main components packed in a 40-foot container or flat rack depending on configuration. Parts get anti-rust coating and durable wrapping. Shipping is typically arranged within 30-45 days after order confirmation from ports such as Shanghai or Qingdao.
What are the KT7C dimensions and weight?+
The KT7C measures 10,000 × 2,500 × 3,200 mm and weighs 15,000 kg. Those figures cover the track-mounted rig as specified. The heavy-duty track undercarriage provides stability during drilling.
