Rapid Bridge Replacement

Engineered Rigging’s Rapid Bridge Replacement Lift System enables railroads and their maintenance contractors to remove and replace a railroad bridge span in a single day. In addition to substantial time savings, the system also provides a safer method for bridge replacement than traditional barge crane, 2-crane picks or hydraulic cylinder / sliding approaches. The Rapid Bridge Replacement Lift System is proudly engineered and manufactured with domestic materials in the U.S.A.

 

Unique Design

Engineered Rigging’s 250 or 500+ ton Rapid Bridge Replacement Lift System is comprised of four mechanically engaged lift columns (two at each end), a horizontal lift girder connecting the columns, drivable trolleys that guide the bridge span along the lift girder, and transport carts to carry away removed spans and deliver replacements.

Top-of-Rails Design: installs on top of the rails, rather than under, eliminating the need for extensive below-rail modifications to adjacent sections

Enclosed Lift Girder: doubles as a safe passageway, enabling crews to cross from one side of the bridge to the other once the span is removed

Modularity: eases handling, shipping and setup

Easy Transport & Rapid Assembly

By setting up this bridge replacement system on a nearby spur, rail service is not interrupted during assembly.

  • Assembles in three to four shifts
  • Ships to rail spur on four to five legal flatbed trailers
  • Requires no wide load or heavy load permits

 

Safe, Fast Operation

Railroads can use the Rapid Bridge Replacement Lift System to safely exchange a bridge span in just one day, significantly less time than hydraulic cylinder methods. Depending on the number of spans, railroads can safely and efficiently complete an entire bridge replacement in days rather than months.

Mechanically Engaged Lifting: no cable drums or strands that can fail or hydraulics that leak

Self-Locking Lift Columns: perfectly synchronized lifting and positive mechanical engagement 100% of the time

Power Failsafe: lift columns that maintain stability during power outage

Remote Operation: lifting and transport controlled from a safe distance
