In this blog, we’ll take a deep dive into SIT’s civil capabilities and the scope of supply we offer to meet the needs of these intricate systems.

SIT’s Expertise in Heavy Moveable Structures

Heavy moveable structures require an intricate blend of engineering disciplines, and SIT stands at the forefront of this technology. Whether it’s bridges, floodgates, or ferry ramps, SIT’s engineers bring the skills needed to design and execute projects that meet strict regulatory and operational specifications.

Types of Heavy Movable Structures

SIT specializes in a range of heavy moveable structures that are essential for civil infrastructure. Below are some of the key types we work on:

Swing Bridges

Swing bridges rotate horizontally to allow passage for marine traffic. SIT designs and implements systems that ensure smooth operation even in harsh conditions, where reliability and precision are critical.

Bascule Bridges

These types of bridges feature sections that pivot upwards to allow ships to pass. Our systems use hydraulic power to guarantee safe, reliable lifting mechanisms, which are crucial in coastal and riverine locations.

Swing Gates

For secure passage management, swing gates are used in both water and land applications. SIT integrates fluid power and automation solutions that make the operation of swing gates efficient and durable, ensuring long-term performance.

Flood Gates

Designed to protect infrastructure from flooding, these gates are critical for areas prone to extreme weather. SIT’s flood gates are engineered for strength and resilience, helping to safeguard against environmental hazards.

Ferry Ramps

Ferry ramps play a vital role in maritime transport. Our systems use hydraulic and electrical automation to ensure seamless operation, allowing for safe and efficient vehicle loading and unloading.

Locks and Dams

Locks and dams are integral to controlling water levels and aiding in navigation. SIT’s expertise in hydraulic systems is particularly well-suited for the precise movement of these heavy components, making them reliable in long-term usage.
