180 Ton Bridge Girder Launcher for Highway Project in Indonesia

Project Background

Java Island expressway projects require advanced bridge construction during ongoing Indonesian infrastructure upgrades. Large spans and soft soil foundations across rivers demand high-performance equipment. Traditional lifting methods face low efficiency, high costs, and significant safety risks. The contractor introduced high-automation bridge girder launcher for continuous prefabricated beam installation.

Bridge Girder Launche Selection and Solution

HSCRANE provided a 180t bridge girder launcher solution for prefabricated box and T-beams. The equipment uses a double-truss structure and stepping-type forward movement for autonomous pier-to-pier travel. It integrates beam transport, feeding, and installation to reduce auxiliary equipment needs.

Bridge Girder Launche Technical Specifications

• Rated Lifting Capacity: 180 tons
• Applicable Span: 30–50 meters
• Beam Types: Prefabricated box beams / T-beams
• Lifting Height: Approximately 20 meters
• Longitudinal Travel Speed: 0–5 m/min
• Transverse Travel Speed: 0–3 m/min
• Lifting Speed: 0–0.8 m/min
• Control System: PLC and frequency conversion control
• Operation Mode: Wireless remote and cabin control
• Power Supply: 380V / 50Hz (3-Phase)

The modular design facilitates long-distance maritime transport and rapid on-site assembly.

Project Implementation

The bridge girder launcher underwent factory pre-assembly and load testing before Indonesian shipment. HSCRANE technical teams managed installation and debugging within 10 days for immediate operation. The bridge girder launcher performs continuous installation following a strict professional sequence:

• Beam carriers deliver prefabricated beams to the rear section.
• The lifting system completes the hoisting process.
• The bridge girder launcher moves forward to the designated bridge position.
• Precise beam lowering completes the installation process.

High automation levels effectively eliminate human operational errors.

Project Advantages and Highlights

Efficient Construction: Continuous operation completes one span every 2–3 days, increasing efficiency by 30%.

• Stable Structural Design: High-strength steel main girders and double-guide systems ensure high-altitude stability.
• Intelligent Control: Frequency conversion and PLC systems achieve precise positioning and smooth operation.
• Environmental Adaptability: The design suits mountains, rivers, and soft foundations without heavy ground cranes.

Client Evaluation and Summary

Clients report stable operation and low failure rates during continuous construction cycles. High automation reduces labor costs and shortens the overall project timeline. The successful 180t bridge girder launcher implementation demonstrates HSCRANE expertise in bridge equipment. This project provides a reliable solution for similar international infrastructure engineering challenges.
