FORWARD Technology deployed a synchronized multi-hoist control system at China Railway No.1 Engineering Group's rail storage yard. Powered by the Gray Bus Positioning System, 32 hoists operate in perfect synchronization with ±5mm positioning accuracy and <15mm error. Workforce reduced from dozens to one, with significant gains in safety and efficiency. Ideal for rail welding plants, storage depots, and long-load handling facilities.
Wuhan FORWARD Technology delivered an intelligent slab yard system for Pangang's 2050mm hot rolling line, deploying Gray Code Bus positioning on 10 cranes with ±5mm accuracy. Results: 3% restacking reduction, 2.2% production increase, 10.9% energy savings, 30% defect reduction. A proven solution for steel industry digital transformation.
Huafeng Coking Plant previously relied on manual vehicle coordination, which suffered from inaccurate positioning and significant safety risks. FORWARD Technology deployed a five-vehicle interlock system using Gray code bus positioning technology to achieve precise positioning and interlock control for pushing cars, coke guide cars, locomotive cars, charging cars, and smoke guide cars, with positioning accuracy of ≤5mm. The system prevents accidents such as red-hot coke falling and pushing rod scraping against oven walls, improving production safety and operational coordination.
This case study examines the unmanned cyclone well slag handling system deployed at LIUZHOU IRON & STEEL CO., LTD. The project retrofitted a manually operated grab crane with Wuhan Forward's proprietary technologies including Gray code positioning, anti‑sway control, laser radar 3D scanning, mobile operation terminals, 3D management and dispatch software, and intelligent scheduling algorithms. The system enables fully automatic operation from slag grabbing to truck loading, eliminating operator exposure to hazardous conditions and delivering measurable improvements: grab cycle time reduced by 15–20%,empty‑grab rate cut from over 10% to below 1%, collision incidents eliminated, and wire rope service life extended by approximately 30%. The solution demonstrates how integrated industrial crane automation can reliably address safety, efficiency, and operational transparency challenges in steel mill environments.
FORWARD Gray Code Bus: electromagnetic induction on coded cable – non‑contact, no drift, instant absolute position. Beats encoders (slippage) and lasers (dust‑sensitive, costly). ±1mm, immune to dust/heat/vibration, multi‑crane sharing, zero maintenance. 10+ year life, lowest annual cost. Direct ProfiNET, open architecture. For automated cranes in harsh environments.
This case study presents an unmanned overhead crane solution for steel coil warehouses, developed through a retrofit project at a major steel producer's finished coil facility. The system integrates high-precision 3D positioning, active anti-sway control, LiDAR scanning, intelligent lifting attachments, and digital twin scheduling—all orchestrated by a centralized warehouse management system to enable fully automated inbound, stacking, restacking, and outbound operations. Post-implementation results include cycle times under 4 minutes per coil, 99.99% operational accuracy, workforce reduction exceeding 60%, and zero safety incidents. The solution is versatile and replicable, offering a proven reference for logistics automation in the steel industry.
