For Traylor Bros, the Liebherr crawlers offer the versatility necessary to precisely align and place bridge sections. The construction contractor planned the deployment of the cranes using Liebherr’ s 3D software Crane Planner 2.0.

receives real-time information about the permissible and actual gradient, and the crane’ s overall center of gravity at all times. If necessary, the main boom angle can be altered so the machine remains in the safe area.
From Planning to Lifting
At the Juneau Creek Bridge, extreme weather conditions, including heavy snowfall, high winds and wide temperature swings impacted operations. Seismic activity in the region also had to be considered for safety in the event of earthquakes. Additionally, the remote location and surrounding natural habitats required careful planning so any ecological impact could be minimized. Steep slopes and limited access roads also made positioning of large bridge components extremely difficult.
Traylor Bros planned the deployment of the two crawler cranes in advance and also during the work using Liebherr’ s 3D software Crane Planner 2.0. By simulating the lifts, the company was able to take all scenarios into account and find solutions for them in advance so that the bridge project could be completed safely, efficiently and on time.
