Los parámetros del proyecto requiere que la grúa necesaria para levantar 33 toneladas utilizando una 300 Boom de pie flotando desde una plataforma en el río. El río Chicago tiene barcazas comerciales pesadas & el tráfico de embarcaciones de recreo que requiere que la mitad del río permanecen abiertas. Este requisito limita el tamaño de la plataforma de la grúa añadiendo otro desafío para el proyecto. Adicionalmente, la grúa y plataforma tenían que cumplir con los estrictos parámetros de seguridad ferroviaria que requieren una capacidad de elevación de la grúa y más grande para el proyecto. El edificio North Riverside se está construyendo más de siete pasajeros activo & líneas de ferrocarril Amtrak. Chicago acero & Clark Construction está utilizando la grúa para la construcción de los pisos inferiores del edificio. Después de la terminación de los pisos inferiores, grúas torre se reúnen para completar el edificio.

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!
