2 × 550T Gantry Cranes for the Mumbai–Ahmedabad High-Speed Train Project

Client Name: Larsen & Toubro
Sector: Construction
Location: Project Location (Surat), Headquarters (Kolkata)

Why did they choose us?

Anupam has been a long-time supplier to L&T for its projects. Anupam is nationally reputed for its high-capacity, heavy-duty cranes.

The Challenge

Problem Statement:

The client required a crane solution to lift a 1100T bridge section that was 40 m long, 12.4 m wide, and weighed up to 1100 tons.

Key Requirements:

A very high-capacity crane capable of handling heavy loads for long durations; a strong design that could withstand wind loads and harsh environments; precise control while handling bridge sections; and sufficient longevity to last the entire project duration.

Our Solution

Overview:

We designed 2 × 550T capacity gantry cranes that work in tandem through Wi-Fi to lift the bridge precast sections.

Design Highlights:

Interconnectivity of the gantry cranes to ensure synchronized lifting and movement; a sturdy design for precise handling in harsh environments; and an extremely large structure compared to regular gantry cranes (Span: 38 m, Height of Lift: 40 m).

Process:

• Design & prototyping
• Fabrication & quality testing
• On-site assembly & commissioning

Timeline: 10 months

Certifications & Safety:

FEM, IS 3177, IS 807. The design was procured from a German company, IBS, which supplied GA drawings and structural calculations. The entire design was analysed using ANSYS software for static calculations. The project timeline was 10 months and was completed on time, which is a major accomplishment for cranes requiring ANSYS simulations. All relevant FEM and IS standards were followed.

Results / Impact

Performance Improvements:

• 20% faster ladle handling operations
• 30% reduction in downtime
• Extended crane life cycle due to robust design

Operational Benefits:

• Improved project productivity
• Safer working environment

This custom-engineered crane provided an efficient solution for handling large bridge sections for the bullet train project and is expected to last well beyond the project timeline with reduced maintenance requirements. This significantly increased productivity for L&T on this project.

Key Takeaways / Summary

Bulleted Highlights:

• Custom-engineered crane for extreme conditions
• Delivered within time and budget
• Tangible productivity gains for the client

Anupam delivered a custom-engineered solution for this project within the contractual timeframe and internal budget, contributing to increased productivity and project efficiency.
