Crane Support Primary Steel Frame Heavy Duty Structural System GB 50205 ISO 9001

Product Description
A Crane-Support Primary Steel Frame is a heavy-duty structural system engineered specifically to withstand crane-induced loads (vertical lift load, horizontal braking force, lateral sway), integrating enhanced load-bearing capacity, anti-fatigue performance, and stability. Manufactured with Q460/Q690 ultra-high-strength steel (main beams, columns) and QT450 ductile iron (crane rail supports), this product features reinforced main beams (box-section or double I-beam, 600×300mm-1200×500mm) with yield strength ≥460MPa, and columns (box-section, 400×400mm-800×800mm) reinforced by stiffeners to resist axial compression and bending from crane operations. The frame is optimized via finite element analysis (FEA) to distribute dynamic loads (5-200 ton crane capacity) evenly, with vertical deflection limited to ≤L/600 (L=beam span) and lateral displacement ≤H/800 (H=frame height). Key features include crane rail support nodes with shockproof rubber pads (Shore hardness 60-70) to absorb vibration, 12.9-grade high-strength bolts with double-nut anti-loosening design, and factory prefabrication rate ≥95% to ensure precision (dimension error ≤±0.8mm). The surface is treated with hot-dip galvanizing (zinc layer ≥100μm) or fluorocarbon coating, providing salt spray resistance ≥1500 hours and adapting to industrial environments (dust, oil fumes). It complies with GB 50205, AISC 360, and EN 1993-1-6 standards, supporting customization of crane capacity (5-200 tons), span (15m-40m), and rail type (QU70-QU120). Professional services include load calculation, fatigue life simulation, on-site installation supervision, and crane operation performance testing.

Applications
Crane-Support Primary Steel Frames are specialized heavy-duty solutions for industrial facilities requiring crane operations, trusted for their load-bearing capacity and durability. Certified by GB 50205, AISC 360, and ISO 9001, they meet strict industrial structural standards. Typical applications include heavy industrial workshops (steel mills, forging plants, machinery manufacturing), logistics and warehousing centers (container yards, port cargo terminals), power generation facilities (coal-fired power plants, wind turbine assembly), and special engineering projects (bridge fabrication yards, offshore equipment workshops). They are particularly essential for facilities with overhead cranes, gantry cranes, or jib cranes, where dynamic loads and repeated operations demand anti-fatigue and high-stiffness structures. The minimum order quantity is 1 set (customized per project), with full tailoring based on crane capacity, span, and load conditions. Competitive project-based pricing and flexible delivery terms (25-50 workdays) support industrial construction schedules, while a monthly supply capacity of 40 project sets ensures timely delivery. Customization options include corrosion-resistant upgrades (super duplex stainless steel), fire-resistant coating (≥2.5 hours) for power plants, and vibration-damping components for high-frequency crane use.
