A rugged job requires a rugged truck, says International Truck and Engine as it rolls out its International 5900i 4×2 tractor. The 5900i is positioned as a light, yet strong construction vehicle, designed in a 4×2 configuration to excel in on/off-highway applications. It requires no additional reinforcing to achieve the durability it needs to survive off the highway, “a unique feature in the severe service market,” the company says.

The 5900i has a set-forward axle and spans 120 inches bumper-to-back of cab. Standard features include a 12,000-pound capacity front axle, a matching parabolic taper leaf front suspension, and a Meritor 23,000-pound rear axle with a Hendrickson HAS 230 rear air suspension.

Standard power is a Cummins ISM engine with 350 horsepower and 1350 pounds-feet of torque. Engine options cover a wide range of Cummins ISM and Caterpillar C-10/C-12 engines with 335 to 430 horsepower ratings and torque ratings from 1350 to 1650 lbs.-ft. Larger displacement engines will be available after October 2002.

To meet the demands of the construction environment, the tractor has a 15-1/2-inch clutch and a Fuller 10-speed overdrive transmission with “C” ratios. Options include Allison automatic, Eaton Fuller 10-speed AutoShift, and various Eaton Fuller 10- to 18-speed manual transmissions.

Inside the cab, Sheppard M-100 power steering, an 18-inch steering wheel, forward instrument panel location, and a high roof add to the driver’s comfort.
