Pamban Bridge

The inauguration of the New Pamban Bridge marks a significant milestone in India’s infrastructural advancements. “The blend of historical reverence with modern engineering.” TRITORC is honored to have contributed to this landmark project by supplying specialized bolting tools required for its construction.

Pamban Bridge: A Legacy Rebuilt

The Pamban Bridge, inaugurated in 1914, being India’s first sea bridge connecting the mainland at Mandapam with the sacred island town of Rameswaram in Tamil Nadu. For over a century, it remained the main link for the movement of people and goods across the Palk Strait. However, with age, weather exposure, and increasing traffic loads, the need for a stronger and more robust replacement became unavoidable.

The newly inaugurated bridge on 6 April 2025 spans 2.08 kilometers and stands as India’s first vertical-lift sea bridge. Its central extent, measuring 72.5 meters, can be elevated by 17 meters to easily evacuate the passage of maritime vessels. 

“The New Pamban Rail Bridge took approximately 7 years to complete.
Construction began in 2017, and the bridge was inaugurated by Prime Minister Narendra Modi. Despite delays due to cyclonic weather, technical challenges, and the COVID-19 pandemic, the project marked a significant engineering achievement with the completion of India’s first vertical-lift sea bridge.”

This innovative design ensures uninterrupted rail connectivity while accommodating sea traffic. Constructed with advanced engineering and materials including stainless steel reinforcements and corrosion-resistant coatings.

The bridge is designed for connectivity of two mainlands without interrupting the marine route. By facilitating easy transportation, the bridge is predicted to contribute to the region’s economic development and tourism and improve the livelihoods of local communities.

TRITORC’s Engineering for the Landmark Project

The Pamban Rail Bridge is not just a replacement structure built today. It is the symbol of India’s growing engineering ambition. The vertical lift design and the high-strength bolted connections, every detail required torque precision, equipment durability, and ergonomic tool handling. “The hallmarks of TRITORC’s product line.”

During the initial stages of the New Pamban Rail Bridge construction, one segment of the major challenges was dealing with a wide variety of bolt sizes and torque requirements across gear couplings, bearing housings, and sliding devices. 

Gear coupling assemblies used M18 bolts that needed to be torqued to 550Nm, while large bearing housings demanded torque values reaching up to 3640Nm with 65mm torque wrenches. The confined workspaces and exposure to a harsh coastal climate added more difficulties, as tools needed to be both compact and corrosion-resistant.
TRITORC tackled this with specially designed compact hydraulic torque wrenches and impact sockets that ensured operation in tight access and salty air. 

Moreover, transverse and longitudinal guides required the installation of M20 bolts at 517Nm, which needed lightweight, high-precision tools to reduce operator fatigue and ensure consistent torque delivery across repetitive tasks. TRITORC supplied customized tools, which included interchangeable torque wrenches and unique reaction arms, making sure that the tools are compatible with different bolt configurations and site conditions.

As the project set forward towards the installation of large structural and mechanical components like the Liftspan guides and gear units, the requirement of bolting gradually increased and complexified. High-load areas used M24 to M48 bolts, requiring torque levels from 890Nm to over 6600Nm. 

Furthermore, critical locations such as foundation bolts for the gear units and hydraulic brake flanges also demanded precise torquing for structural stability. The challenge was providing torque accuracy under high load without operator fatigue. The tools to use needed to be compact yet provide high torque to large-size bolts, especially for M48 bolts that needed 75mm sockets and up to 6650Nm of torque. 

TRITORC deployed its customized heavy-duty TSL and THL series torque wrenches. Custom reducers and socket extensions were supplied to easily work in complex assemblies. Prompt on-site support ensured tools were fine-tuned as per evolving requirements. This adaptive engineering approach allowed TRITORC to address each challenge with tailored tooling, ultimately enabling fast, safe, and precise assembly of one of India’s most iconic infrastructure projects.

Our hydraulic torque wrenches and impact tools are engineered to deliver consistent force, essential in load-bearing structures exposed to dynamic stresses, sea winds, and corrosion.

The construction of such a massive and sophisticated structure demanded precision and reliability in every component used.
We supplied a set of specialized tools to meet some major requirements: (WITH IMAGES)

  1. Hydraulic Torque Wrenches (Models: TSL-07, THL-8, THL-2)
    These tools provided accurate torque, securing critical joints and ensuring structural integrity.”
  2. Heavy-Duty Impact Sockets and Stack Sockets
    Designed to withstand high torque and secure fastening of large bolts used in the bridge’s framework.”
  3. Impact Reducers and Spanner Housings
    These accessories are used for adaptability in bolting operations across various components.”
