Crane Rental Corporation completes several heavy haul jobs
24 June 2014Crane Rental Corporation has completed several heavy haul projects in the US involving storage tanks and transformers.
Two projects in the Northeast involved a 291,000lbs propane tank and a 409,000lbs surge tank. Florida-based Crane Rental offloaded the 151ft long and 14ft wide propane tank from a rail spur using 700t capacity gantries before transportation 52 miles on a dual-lane extending-axle transport trailer using a dolly configuration.
The trailer's axles expanded from 14 to 20ft to more evenly distribute weight over bridges.
The other Northeast project saw a 157ft long and 13.5ft wide surge tank offloaded from a rail spur using 700t gantries, before transportation 32 miles on tow-hitch modular Goldhofer trailers.
In the Southeast, a fully assembled 237,000lbs transformer was moved from its pad onto a six-line self-propelled Goldhofer and transported to a containment area. A new 186,000lbs transformer was then offloaded, moved on a six-line Goldhofer trailer and set in place using a 600t Terex AC500-2 hydraulic truck crane.
Another Southeast project saw Crane Rental remove a 300,000lbs transformer and hoisting it with the 700t gantry system onto an 18-axle self propelled trailer.
The Dura-Base mat system was required to mitigate ground-bearing pressures on a site with tight clearances and underground utilities.
