Heavy-duty transport solutions engineered for optimal safety, high-load capacities, and rigorous underground mining conditions.
Italy’s mining and underground tunneling industries are characterized by highly specialized operations, historical depth, and strict modern environmental and safety frameworks. The Italian geological structure, ranging from the rugged Alps in the north to the Apennines running down the peninsula, demands advanced engineering solutions. Heavy transport equipment, such as the Longwall Chock Carrier, plays a crucial role in modern subterranean infrastructure projects, large-scale civil excavations, and deep mining operations.
While traditional coal mining in regions like Sardinia (specifically the Sulcis basin, known for its historic coal reserves) has transitioned toward sustainable and research-oriented underground laboratories, Italy’s tunneling sector has expanded rapidly. The country is a European leader in constructing complex railway and highway tunnels, such as the Brenner Base Tunnel and various Alpine transit links. In these environments, transporting heavy structural supports, shield components, and hydraulic roof chocks through narrow, steep, and explosive-risk underground pathways requires robust, reliable, and high-capacity carrier machinery.
Underground operations in Italy face unique challenges that necessitate the deployment of specialized vehicles like the WC50Y and WC50Y(B)-50T chock carriers:
The global trend in underground logistics is shifting toward automation, lower emissions, and integrated hydraulic control. Modern chock carriers are no longer just mechanical haulers; they are sophisticated mobile platforms. The integration of high-pressure hydraulic sealing sets and ultra-durable rubber hoses ensures that power transmission remains flawless under high-stress conditions. As a leading manufacturer, Kelong New Materials ensures that all hydraulic assemblies and heavy carriers meet these evolving parameters, providing Italian contractors with high uptime and reduced maintenance costs.

Our Longwall Chock Carriers are uniquely suited for the following core industrial sectors in Italy:
Italy is continuously expanding its transportation network through mountainous regions. Excavating tunnels using large Tunnel Boring Machines (TBMs) requires heavy structural shields and supporting chocks to be moved constantly. The WC50Y(B)-50T carrier, with its 50-ton hydraulic loading capacity, offers the ideal footprint and power to transport these heavy shields from assembly chambers to active tunneling faces, navigating steep gradients and damp conditions safely.
As Italy invests heavily in renewable energy storage, underground pumped-storage hydroelectric plants are being constructed or retrofitted. Creating these massive caverns requires robust heavy-haulage equipment that can move hydraulic supports and heavy structural beams. Our carriers provide the necessary traction, load capacity, and precise control to maneuver in confined spaces without compromising structural safety.
While primarily designed for underground coal mines, the extreme load-carrying capabilities of the 55/70T LWC Longwall Chock Carrier find parallel applications in Italy's world-famous marble quarries. Moving massive stone blocks and transporting heavy lifting machinery across loose, steep, and unpaved quarry roads requires vehicles with heavy-duty drivetrains and advanced hydraulic stability control systems.
Partnering with Kelong New Materials ensures a reliable supply chain from our advanced manufacturing hubs in China directly to major Italian ports like Genoa, Trieste, and Naples. We offer complete technical documentation, CE compliance support, and customization of hydraulic interfaces to match European auxiliary equipment standards. Our team of 180+ engineers is available to provide remote commissioning assistance and custom design modifications, ensuring that our carriers integrate seamlessly into your fleet.
