Product Detail
Heavy-Duty Workshop Challenges & Our Crane-Ready Solutiontion
Heavy industry operators need workshops that support massive overhead cranes for equipment assembly, steel fabrication, and heavy machinery maintenance. Standard portal frames often lack the column stiffness and runway beam capacity for cranes above 20 tons. Our prefabricated crane steel structure workshop solves this. Using Q345B/Q355B welded H-type, box-type, cross-type, and T-type members, the portal frame is specifically engineered for 10-50 ton overhead bridge cranes with eave heights of 8-15m. Columns are reinforced with stiffener plates at crane runway connection points, and fatigue-rated welded connections per GB 50017 ensure long-term crane loading reliability. For a 2,500 m² heavy-duty workshop with 32-ton crane capacity, the complete steel frame erects in 30-45 days versus 6-9 months for reinforced concrete.
Product Advantages
• Heavy crane integration: Columns and runway beams pre-engineered for 10-50 ton overhead bridge cranes with fatigue-rated welded connections per GB 50017.
• Reinforced columns: Stiffener plates at crane runway connections and increased column section modulus prevent lateral deflection under crane loads.
• High eave clearance: 8-15m eave heights accommodate jib cranes, hoists, and tall product assembly below the bridge crane.
• Fire-rated cladding: Rock wool sandwich panels (100-150mm, fire resistance ≥2 hours) for walls and roofs meeting heavy industry fire codes.
• Vibration control: Column base plates and bracing systems engineered to minimize crane-induced vibration affecting precision assembly.
• Multi-span expansion: Continuous portal frames support future bay additions without disrupting existing crane operations.
Welding Qualification & Fatigue Testingting
Crane workshop structures demand the highest welding and fatigue standards. Our shop holds the China Steel Structure Manufacturing Special Level Qualification. Welding procedures are qualified to ISO 15614-1, and all welders carry ISO 9606 certifications. For crane runway beams and column connections, 100% of full-penetration butt welds undergo ultrasonic testing (UT) per GB/T 11345, with 20% radiographic testing (RT) spot checks on fatigue-critical details. Magnetic particle inspection (MT) is applied to all fillet welds at crane connection points. We also hold the Italy Welding Procedure Qualification Certificate for CE-marked crane workshop components. Each shipment includes a complete material traceability dossier with fatigue detail classification per ISO 10721.
