Proje parametreleri, vincin kaldırılmasını gerektiriyordu. 33 kullanarak ton 300 nehirdeki bir platformdan yüzen ayak patlaması. Chicago Nehri'nde ağır ticari mavna var & nehrin yarısının açık kalmasını gerektiren gezi teknesi trafiği. Bu gereklilik, projeye başka bir zorluk ekleyerek vinç platformunun boyutunu kısıtladı. Ek olarak, vinç ve platformun, proje için daha büyük bir vinç ve kaldırma kapasitesi gerektiren katı demiryolu güvenlik parametrelerini karşılaması gerekiyordu. North Riverside binası yedi aktif banliyö üzerinde inşa ediliyor & Amtrak demiryolu hatları. Chicago Çelik & Clark İnşaat, binanın alt katlarını inşa etmek için vinç kullanıyor. Alt katların tamamlanmasının ardından, binayı tamamlamak için kule vinçler monte edilecek.

The Poseidon® Barge engineering and sales staff met with Chicago Steel Engineers to discuss and plan the project. Analysis determined that a 99’ x 132’ x 10’ platform would be suitable for the project requirements. Two layers of wood mats and steel plating were installed under the crane to ensure spreading the load of the crane over the platform surface. Stability analysis was completed to ensure that the list and trim parameters were not exceeded.

The platform was constructed using the Poseidon® P10 Portable Sectional Barges, first introduced at Con-Expo in March of 2014. The platform consists of 23 – P10 44’ x 11’ x 10’ sections and 8 – 22’ x 11’ x 10’ sections. The platform was assembled 4 miles south of the project site. Chicago Steel used a Manitowoc 2250 crane to offload the sections from the truck and set them into the water. A crew of three men assembled the barges in the water. After staging the barges on land and blocking the female pins in the up position, the crew was able to assemble 5 – 44’ units and 2 – 22’ units in a 22’ x 132’ configuration in two hours.

Poseidon® Barge and Chicago Steel were assisted by Thatcher Foundations Inc. Thatcher assisted with their tug boat as well as helping to install the one million plus pounds of counter weights on the crane at the construction site. Kindra Lake Towing played an integral role in planning and moving the platform four miles upriver to the construction site, after assembly was complete. The platform was moved on a Sunday morning to lessen the impact on traffic in downtown Chicago as bridges would have to be raised to allow the crane and platform to pass underneath.

Thank you to Chicago Steel, Clark Construction, Kindra Lake Towing and Thatcher Construction for their support of Poseidon® Barge!
