Mining Equipment Frame Fabrication
Mining equipment operates in the harshest environments with extreme loads, vibration, and abrasive conditions. Our heavy structure fabrication services for mining industry include crusher frames, conveyor support structures, mill housings, and excavator components. We work with high-strength structural steels (Q345, S355, S460) and wear-resistant plates (Hardox, AR400) to ensure long service life in demanding mining applications. Welding procedures are qualified for thick sections up to 150mm with full penetration welds and 100% NDT inspection.
Large mining equipment frames require precise fit-up and alignment to prevent premature bearing failure and structural fatigue. Our 50-ton overhead cranes and heavy-duty welding positioners allow proper manipulation of massive weldments. Post-weld stress relief through vibration or thermal treatment eliminates residual stresses that could cause distortion during service. Final machining on our 12-meter gantry CNC ensures mounting surfaces meet flatness and parallelism specifications within 0.1mm across multi-meter spans.
Port Machinery and Container Handling Equipment
Port cranes, container spreaders, and cargo handling equipment demand exceptional structural integrity and fatigue resistance. We fabricate main girders, boom structures, and support frames for ship-to-shore cranes, rubber-tired gantry cranes, and rail-mounted gantry cranes. EN1090 EXC3 execution class ensures compliance with European crane standards, while ISO 3834-2 welding certification guarantees weld quality for fatigue-critical applications. All structural welds undergo magnetic particle or dye penetrant inspection to detect surface defects.
Port equipment structures face corrosive marine environments requiring robust surface protection. We provide complete coating systems including abrasive blasting to Sa 2.5 standard, zinc-rich epoxy primers, and polyurethane topcoats for C5-M corrosion category. Hot-dip galvanizing is available for smaller components requiring maximum corrosion protection. Load testing and proof loading can be arranged to verify structural capacity before shipment to port facilities worldwide.
Industrial Press and Machine Tool Bases
Precision manufacturing equipment requires rigid, vibration-damped base structures to maintain machine accuracy. We fabricate welded steel bases for hydraulic presses, stamping machines, CNC machine tools, and industrial robots. Base frame design incorporates ribbing and gussets for maximum stiffness while minimizing weight. Welding sequence is carefully planned to control distortion, followed by stress relief and precision machining of mounting surfaces. Flatness tolerances of 0.05mm per meter are achievable on machined surfaces.
Large press frames and machine bases often exceed 20 tons and require special handling during fabrication and installation. Our facility is equipped with heavy-duty floor space, overhead cranes, and transport equipment to manage oversized structures. We coordinate with rigging companies and freight forwarders to ensure safe delivery to customer facilities. Installation support including alignment, grouting, and commissioning assistance is available for complex equipment installations.
Construction and Earthmoving Equipment Structures
Construction equipment manufacturers require reliable fabrication partners for excavator booms, bulldozer frames, loader buckets, and crane components. We manufacture structural weldments from engineering drawings or customer-supplied models, maintaining tight tolerances on critical dimensions and hole patterns. High-strength low-alloy steels and abrasion-resistant materials are stocked for quick turnaround on production orders. Robotic welding cells provide consistent weld quality and high productivity for repetitive components.
