Manufactured from high-strength forged steel for superior material integrity.
Precision-machined to ensure smooth, stable operation and minimize wear.
Undergo specialized heat treatment for optimal strength and durability.
Feature a robust structural design to withstand heavy loads and shock.
100% non-destructive tested to guarantee internal quality.
Application Fields:
Overhead bridge cranes in steel mills and metallurgical plants.
Heavy-load handling systems in port container terminals.
Major component assembly lines in shipbuilding yards.
Critical material handling in power generation and heavy equipment facilities.
Large-scale logistics and manufacturing warehouses.
| Item | Details |
|---|---|
| Material | 4140 Alloy Steel – Provides outstanding shock resistance, fatigue durability, and wear resistance, perfectly adapted to the dynamic heavy-load operation scenarios of overhead bridge girder travel systems |
| Forging Capability | Hydraulic Hammers: 5T / 8T / 12T – Realize deep plastic deformation and directional grain refinement in the open die forging process, optimize the internal structure of the wheel, and match the high-strength operation requirements of overhead bridge girder systems |
| Main Application | Specialized for overhead bridge girder travel systems, and also applicable to large-scale lifting equipment such as gantry cranes, port cranes and heavy-duty container carriers under high-load working conditions |
| Production Process | Open Die Forging → Heat Treatment (Normalizing + Tempering) → Rough Machining – The whole process ensures high strength and dimensional precision, and lays a solid foundation for the stable operation of the overhead bridge girder travel system |
| Deformation Ratio | Forging Ratio ≥ 3.0 – Optimizes grain flow direction, strengthens the load-bearing structure of the wheel, and effectively reduces the risk of internal fatigue failure during the reciprocating travel of the overhead bridge girder |
| Delivery State | Rough-machined + Heat-treated finished products, with stress relief treatment included – Avoid deformation during the final machining of the wheel or long-term service in the overhead bridge girder travel system |
| Inspection Tools | Full-set precision testing equipment: Spectrometer, UT device, tensile & impact testing machines, metallographic microscope, micrometers, bore indicators, hardness testers, etc. – Achieve full-process traceable quality control to meet the safety standards of overhead bridge girder systems |
| Service Package | Tiangong Forging provides one-stop integrated services covering forging, machining, heat treatment, quality inspection, customized packaging, port clearance and global shipping coordination – Fully customized according to the technical specifications of overhead bridge girder travel systems, and comply with international industry standards |
