Product Description

Modular Steel Cable Suspension Bridge Overview

Our modular steel cable suspension bridge is a flexible suspension system combining main cables and stiffened beams, offering the structural advantages of both cable and beam systems. Engineered for large spans exceeding 1000 meters, this bridge type is the preferred choice for major infrastructure projects worldwide.

Key Structural Components

Main Cable: Primary load-bearing component transmitting forces to anchors and towers
Bridge Tower: Supports vertical loads with rigid, flexible, or rocking column designs
Stiffening Beam: Secondary structure ensuring vehicle stability and providing structural stiffness
Sling/Stay Cables: Force transmission elements connecting stiffened beam to main cable
Anchorage: Structures anchoring main cable tension to foundation
Saddle: Critical component supporting main cable at tower tops and anchors

Bridge Classification

By Suspension Span Count

Single-span suspension bridge
Three-span suspension bridge
Four-span suspension bridge
Five-span suspension bridge

By Main Cable Anchoring

Ground Anchorage: Main cable tension transferred to foundation via gravity or tunnel anchors
Self-Anchoring: Main cable tension transmitted directly to stiffening beam
