Volvo Trucks is offering a version of its VNX 630 model with three rear drive axles to increase the traction and load capability of the vehicle. The VNX 630 tridem is an 8x6 configuration designed for operating in steep terrain, mud, ice and in other off-road applications.
The VNX 630 tridem can manage up to a 69,000 pound rear axle load and is equipped with the Volvo D16 engine, rated up to 600 horsepower and 2,050 lb.-ft. of torque, mated to a Volvo I-Shift automated manual transmission.
“Power and performance are two benefits our heavy-haul customers demand,” said Gӧran Nyberg, president of Volvo Trucks North America. “The VNX tridem meets these needs, offering a solution to ensure the easier transportation of heavy-haul loads.”
The VNX 630 features a mid-roof sleeper with Volvo’s ergonomic dash, and interior space that can be optioned in trim levels ranging from vinyl for rugged applications to leather for driver comfort. The truck also has safety features like a sloped hood and large windshield for visibility, standard driver’s side airbags and a cab made of high-strength steel.
Also standard on all models equipped with Volvo powertrains is Remote Diagnostics, which provides repair planning assistance and detailed analysis on critical diagnostic trouble codes. The service also helps improve parts availability and provides technicians with repair instructions before a truck arrives for service, according to Volvo.
