Crane Runway Connection Joint Wear Resistant for fixing crane rails to steel beams

Product Description
A Crane Runway Connection Joint is a heavy-duty and wear-resistant structural node designed for fixing crane rails to steel beams, engineered to withstand vertical loads, lateral horizontal forces, and longitudinal braking forces during crane operation. Manufactured with Q355B high-strength steel (base structure) and QT450 ductile iron (rail clamping components), this product offers exceptional load-bearing capacity (vertical load ≥50kN/m) and wear resistance (surface hardness HB 200-250 for ductile iron parts), ensuring stable operation of 5-50 ton bridge cranes and gantry cranes. The joint features a modular design with shockproof rubber pads (Shore hardness 60-70) between the rail and steel beam, which absorb vibration and reduce noise during crane movement, protecting both the crane and the connection node. High-strength bolts (10.9 grade) with double-nut anti-loosening design secure the rail, preventing displacement under dynamic loads, while the CNC-machined clamping surfaces ensure precise rail alignment (levelness error ≤2mm/m). The surface is treated with hot-dip galvanizing (zinc layer thickness ≥85μm) for corrosion resistance, adapting to industrial workshop environments (dust, oil fumes). It complies with GB 50205 steel structure engineering construction quality acceptance standards and is optimized via dynamic simulation to ensure fatigue resistance under frequent crane start-stop cycles (100,000 cycles without structural damage). Professional services include load-bearing capacity calculation based on crane tonnage, on-site installation guidance, and periodic maintenance inspections, ensuring long-term safe operation of the crane system.

Applications:
Crane Runway Connection Joints are heavy-duty node solutions specifically designed for industrial crane systems. Certified by GB 50205 and ISO 9001, they meet strict quality standards for industrial load-bearing structures, ensuring reliable performance in heavy-load and dynamic scenarios. These joints are suitable for diverse industrial applications, including 5-50 ton bridge crane runways in heavy machinery workshops, gantry crane rail fixing in logistics and warehousing centers, overhead crane systems in steel mills and foundries, and special crane (explosion-proof, high-temperature) rail connections in chemical plants and power stations. They are critical for industrial facilities where cranes are core equipment, ensuring smooth material handling and operational safety. The minimum order quantity is 10 sets for standard specifications (compatible with rail types QU70, QU80, QU100), and customized solutions are available for crane tonnage (up to 100 tons), rail model, and installation environment (high-temperature, corrosion-prone) to meet specific industrial needs. Competitive pricing and bulk purchase discounts (for orders over 50 sets) enhance cost-effectiveness, while the delivery time (7-12 workdays for standard orders) supports industrial workshop construction and renovation schedules. With a monthly supply capacity of 1,000 sets, the manufacturer ensures timely delivery even for large-scale industrial projects. The high-strength steel and ductile iron materials, combined with hot-dip galvanizing treatment, ensure durability in harsh industrial environments (dust, moisture, chemical vapors). Customization options also include high-temperature resistant rubber pads (up to 200℃) for high-heat workshops and corrosion-resistant 316L stainless steel components for chemical plants. Whether it's for new workshop construction or old crane runway renovation, the Crane Runway Connection Joint delivers stable and durable rail-fixing performance.
