HSCRANE 200-Ton Bridge Girder Launcher Successfully Installed in Saudi Arabia Bridge Project

Saudi Arabia has seen rapid growth in bridge construction demand, especially for expressways and urban viaducts. Local engineering teams needed a high-capacity bridge girder launcher that can withstand high temperatures and harsh environments for a desert expressway bridge project. After market research and technical evaluation, HSCRANE 200-ton bridge girder launcher was selected for the project.

Installation and Construction Overview

The girders weighed 150–200 tons with spans up to 45 meters, and ambient temperatures exceeded 45°C with strong winds. HSCRANE provided full technical support, including transport, assembly, commissioning, and training.

After arrival, the team completed support leg installation, main girder assembly, and control system commissioning following standard procedures. The commissioning focused on stability, synchronization control, and movement accuracy to ensure safe operation under high temperature and wind load.

Operation Process and Efficiency

The HSCRANE 200-ton bridge girder launcher efficiently completed multi-span girder erection, demonstrating reliable performance in high-intensity, long-span construction. The workflow included:

•Girder transport to site: Precast girders were transported to the lifting position using girder carriers or rails, ensuring stability and avoiding imbalance or swaying.

•Lifting point arrangement: Lifting points were arranged based on weight, length, and center of gravity, using high-strength rigging for safe lifting.

•Girder lifting: The hoisting mechanism lifted girders slowly with uniform load distribution, while the control system monitored posture to prevent imbalance and swinging.

•Longitudinal movement: Girders moved smoothly along the main girder to the target span, with synchronized lifting points ensuring balance.

•Transverse fine adjustment and placement: The transverse mechanism made fine adjustments to align girders with bearing centerlines, keeping placement error within millimeters.

•Equipment advancing cycle: After one span, the launcher advanced to the next span and repeated the process for continuous erection.

Due to its scientific design and mature control system, the 200-ton launcher averaged only 6 hours per span, reducing time by about 30% compared with traditional equipment.

HSCRANE Bridge Girder Launcher Product Advantages

•High load capacity: Meets 200-ton girder erection requirements and ensures smooth long-span bridge construction.

•Precise control system: High longitudinal and transverse accuracy with placement error under 10mm, meeting quality standards.

•High temperature and wind adaptability: Optimized structure and cooling system ensure stable operation in Saudi Arabia’s hot environment.

•Full technical support: HSCRANE offers one-stop service from transport and installation to construction guidance, ensuring smooth project progress.

Project Outcome

With the efficient operation of HSCRANE 200-ton bridge girder launcher, the Saudi expressway bridge project completed all girder erection tasks successfully. Construction efficiency improved, safety risks were controlled, and mature, replicable technical experience was gained for future projects.

The bridge girder launcher completed the critical task in Saudi Arabia with high load capacity, precise control, and harsh-condition adaptability, demonstrating HSCRANE’s technical strength and delivery capability in international bridge construction.
