●Upgraded heavy-duty structure, reinforced steel frame for higher structural stability and durability.
●Optimized high-pressure hydraulic system, stable output and improved rock drilling efficiency for hard rock conditions. ● Professional crawler chassis design, 30° strong climbing ability, adaptable to rugged and mountainous terrain.KG500A equipped with integrated high-efficiency dust collector for eco-friendly low-dust construction.
●Mature industrial design, simple operation and convenient daily maintenance, low comprehensive operating cost.KAISHAN KG500 and KG500A are upgraded heavy-duty crawler DTH drilling rigs developed for medium and large-scale open-pit mining, quarry blasting, road engineering and photovoltaic foundation construction projects. Adopting reinforced box-type steel guide rail and thickened crawler chassis, the whole machine features high structural strength, strong shock resistance and outstanding stability during long-hour continuous operation.
Equipped with an upgraded high-pressure integrated hydraulic system and premium core components, the drilling rig realizes stable torque output and fast drilling speed, perfectly adapting to various complex and hard rock formations. With excellent terrain adaptability and 30-degree maximum climbing capacity, it can freely cope with mountainous construction sites, rugged ground and narrow working spaces.
The KG500A upgraded model is equipped with a professional integrated dust removal system, which effectively absorbs construction dust, reduces environmental pollution and meets global green mining and environmental protection construction standards. Featuring reliable power configuration, simple humanized operation design and easy daily maintenance, the drilling rig greatly reduces later maintenance costs and downtime losses.
Durable structure, stable performance and wide application scenarios make KAISHAN KG500/KG500A a cost-effective and trustworthy heavy-duty open-pit drilling equipment for global mining contractors and engineering construction teams.Kaishan KG500/KG500A Open-Pit Down-the-Hole Drilling Rig Specifications
