High-efficiency excavation and auxiliary transport systems tailored for rigorous subsurface operations.



Founded in 1996 from the Xianyang Kelong Rubber Products Institute, Shaanxi Kelong New Materials Technology Co., Ltd. represents the absolute pinnacle of technological innovation, R&D integration, and heavy-duty manufacturing.
Ranked among the top three enterprises in China's domestic coal machine sealing industry, Kelong New Materials continues to dominate core industrial segments. Our high-pressure rubber hoses and frame-type handling vehicles are projected to secure top-three positions nationwide within the next two years, currently capturing an impressive 8% market share. With advanced DMH Austrian sealing technology and complete Italian high-pressure hose production lines, we guarantee uncompromised structural integrity and performance.
Navigating specialized heavy transport equipment demands in emerging and strategic mining territories.
New Amsterdam stands as a crucial nexus point for regional infrastructure development, heavy resource logistics, and secondary industrial expansion. As municipal and industrial sectors modernize, the demand for high-capacity underground mining auxiliary equipment, heavy-duty logistics haulers, and reliable hydraulic support transport has grown exponentially. Local engineering contractors require rugged, certified, and cost-effective machinery capable of withstanding extreme load conditions while complying with strict international safety and environmental regulations.
In New Amsterdam's industrial projects, our Longwall Chock Carrier (such as the WC50Y, WC50Y(B)-50T, WC55Y(A), and WC60Y/WC80Y series) serves critical functions in fully mechanized mining face transitions, heavy hydraulic shield relocation, and underground material haulage. Our technology roadmap emphasizes zero-emission capability, intelligent load sensing, explosion-proof braking systems, and modular maintenance frameworks that minimize operational downtime in deep-shaft environments.
Leveraging China's robust industrial ecosystem, Kelong New Materials integrates end-to-end manufacturing—from polymer compound R&D to precision metal fabrication. This complete vertical integration yields unmatched supply chain resilience, insulation against global raw material volatility, and optimized pricing structures. Global buyers in New Amsterdam and beyond benefit directly from factory-direct pricing, rigorous ISO/IRIS quality assurance, and accelerated logistics fulfillment cycles.
