Center-span girder segment lifting and erection using a stiffening truss with a 400 ton crane for the new Athabasca River Bridge.

We perform structural checks on out-of-province supplier equipment to ensure compliance with project and WCB standards.

Pushing systems in incremental bridge launching: hydraulic jacks, rams, winches, and cranes, each with unique pros and cons.

The launch nose reduces bending moments during bridge girder launches, ensuring smooth transitions and structural integrity.

The launch bed is essential for assembling and moving steel girder segments during bridge construction, tailored to project-specific needs.

This post outlines staging analysis for incremental launching, covering launch stages, FEM creation, and results in the erection manual.

Planning an Incremental Launch: key steps for efficient, safe, and cost-effective bridge construction using the Incremental Launching Method

The Incremental Launching Method a technique used to erect bridge girders. It's suitable for challenging terrains with difficult access.

The final selection of a crane is a collaborative process requiring accurate loads, placement, boom length and checks, and load charts.
