Handan China Railway Bridge Machinery Co., Ltd. (HCR) has executed the first viaduct span commissioning for Phase 1 of Singapore’s Jurong Region Line (JRL) using its advanced LG550 and LG500 Launching Gantries. Completed on schedule despite tropical monsoon challenges, this milestone underscores HCR’s capability to deliver sub-5mm precision in complex urban alignments.
Engineering Excellence Validated
| Model | Technical Superiority vs. Industry Standard |
| LG550 | • Curve Radius: 185m (vs. min. 800m for conventional gantries) • Slope Climbing: 3% gradient capacity (2× standard) • Spatial Efficiency: Operates in 22m-wide corridors |
| LG500 | • 400m Radius: Enables seamless S-curves • 500T Load: Equivalent to 70 fully-loaded trucks • Dynamic Balancing: Auto-counterweights for crosswinds >15m/s |
Commissioning Critical Path
Safety Validation: 328-point checklist per Singapore BCA SS550:2018
Contractor Empowerment: Trained 17 LTA-certified operators
Monsoon Mitigation: Implemented real-time telemetry during 120mm/hr rainfall
Technical Interventions: Resolved 23 issues including:
• Laser guidance interference from steel reinforcement
• Hydraulic drift compensation on 2.8% slopes
• Anti-sway algorithms for 35m cantilever sections
"The LG550’s 185m radius capability was decisive for Boon Lay Station’s helix approach," stated SMRT’s Lead Engineer. "HCR’s solution saved 12 weeks versus segmental methods."
Project Impact:
JRL’s 24km elevated viaduct will reduce peak travel time by 40% for 200,000 commuters upon 2029 opening.
