Acrow Responds to Metro NY/NJ Rail Bridge Emergency with Superprop® System.

NEWS RELEASE
August 01, 2001

For the second time within a 30 day period Acrow Corporation was asked to respond to a bridge emergency requirement in the metro NY/NJ area. This particular case was a through girder railroad bridge, which apparently weakened over years of usage, and required immediate reinforcement following an inspection.

The consulting engineering firm managing the large project described the problem on the phone to an Acrow engineer. Acrow’s engineers were then able to design a shoring solution, overnight, using the Acrow Superprop system. Acrow Superprop equipment was delivered to the job site within 12 hours and the entire shoring system was erected within a day. The rail bridge required 23 Superprops located strategically in accordance with the engineering design. The design loading is the heaviest railroad loading in the USA and it is called AREMA Cooper E-80.

One Acrow Superprop has the capability to support 250 tons unbraced to heights of 40 feet. The Acrow Superprop is one of the most versatile, compact (20 inch diameter) and easy to install shoring systems in the construction industry. It is completely modular, and it pins and bolts together. The head of the Superprop extends 1.4 feet using standard hydraulic jacks. After the Superprop has been extended, simply turn the collar nut until it seats and remove the hydraulic jacks.

Acrow Superprop and Bridge products are rented or sold depending on the customer’s need.
