According to Terex, the Crossover 8000, with a rated lift capacity of 80 tons, blends truck crane and boom crane designs to offer a 360-degree load radius that out lifts any other boom truck in North America. Featuring the same upper structure as the Terex T780 telescopic truck crane, the Crossover 8000 boom truck offers almost identical load ratings throughout most lift situations, says the company, regardless if lifting from the front, rear or sides of the crane.
The Crossover 8000 crane uses the Terex X-pattern outrigger design, which, says Terex, lowers the overall center of gravity and isolates the crane’s upper structure from the truck chassis, reducing chassis torsion and extending chassis life. The three-position outrigger system also is designed to eliminate the need for a front stabilizer jack, thus decreasing overall length and weight of the crane, says the company.
The Crossover 8000’s four-section main boom offers a 126-foot length with a 189-foot maximum tip height. Two available jib designs—a fixed length 33-foot and an extendable to 57 feet—provide 0-, 15- and 30-degree offset positions. The new crane can be equipped with either one or two winches, giving the flexibility, says Terex, to handle complex lifts. The crane’s top swivel ball with hook and latch is rated at 7 tons; alternatively, says the company, the available quick-reeving hook block features five sheaves to offer the 80-ton capacity (rated at a 10-foot radius).
The Crossover 8000 is the first boom truck to use the latest Terex operator’s cab, which has an infinitely variable tilt-up feature of up to 18 degrees for enhanced vision of the work area. The cab features a new air conditioning and heating system with individual air outlets, and the multi-adjustable seat has air-ride suspension, high back and arm rests.
The upper lift structure has been approved for Freightliner, Kenworth and Western Star chassis; other options can be investigated to offer flexibility in crane configuration, says Terex.
