Mounted on a Western Star chassis, Dynamite's new Terex Crossover 6000 was ready to work.

Dynamite’s Terex Crossover 6000 crane arrived at Clairmont ready to work, mounted on a Western Star chassis with twin steering axles and a tri-drive axle configuration. However, in order to carry the additional 12,000 lbs (5443 kg) of removable counterweight, local restrictions state that an additional steering axle was required. To achieve this, Decca contracted Simard Suspensions Inc. in Baie-Saint-Paul, Quebec to tighten the steering axle spacing and install an additional axle. The expanded footprint not only allowed for the counterweights to be legally carried on the sub-frame, but also increased capacity enough to allow the installation of an oilfield style, heavy-duty pipe bumper. Furthermore, the entire crane structure was moved forward, lessening the load carried by the rear axles, and providing more room for Decca to tackle the next goal for their customer, towing a trailer.

In order to pull a trailer behind the Crossover 6000 crane, a high-rise fifth wheel pedestal was designed, as well as a custom trailer to match it. The pedestal was designed to mate with the crane outriggers while in transport for additional strength. The pedestal itself was then able to remain hollow and be utilized as a sizable storage cabinet. The tri-axle trailer was specifically designed for Dynamite’s Crossover truck crane, complete with two drop axles and a 28 ft (8.5 m) long deck, bringing the entire coupled unit just under the maximum legal length for travelling on western Canadian highways.
