Crane Rental Corporation recently hauled a 360,000-pound transformer with a loaded height of 17 feet, eight inches, on a dual-lane Trail King trailer made in 2013 to Crane Rental Corporation’s specifications.
The innovative, high-capacity trailer features telescoping axles that extend from 12 to 20 feet to accommodate over-dimensional loads and more evenly distribute loads over bridges and culverts. It offers suspension beam, perimeter deck, dollies, or bolster options.
The entire job took just five days, including a fifty-mile haul in central Florida during which Crane Rental Corporation’s dual-lane trailer was accompanied by six police and two civilian escorts. A T800 Kenworth four-axle tractor with an automatic transmission, 500HP engine, and 70,000-pound planetary rear axles pulled the entire load (approximately 700,000 pound gross) without hesitation.
At the initial storage site, the team loaded the transformer onto the 24-axle dual-lane trailer using Crane Rental Corporation’s 700-ton gantries. When the load arrived at its final destination, the transformer was trans-loaded by the same gantries from the dual-lane trailer onto Crane Rental Corporation’s 12-line Goldhofer self-propelled modular hydraulic platform trailer in order to maneuver through the tight site.
Once in the substation, the hydraulic trailer positioned the transformer exactly where it was needed. Then the 700-ton gantries were assembled for a third time to offload the unit to its final resting position.
