CAT® Vocational Trucks

New Cat Vocational Trucks

In March 2011, Caterpillar unveiled the first model in their highly anticipated new line of Vocational Trucks. Before Caterpillar engineers started designing it, they asked vocational truck customers what they wanted and needed from their trucks. Cat engineers and designers were focused squarely on making this customer input a reality and they delivered a full line of Vocational Trucks that are built for the jobs you do.

The CT660 model Vocational Truck started rolling off the line in mid-2011, and they have proven they can handle a wide range of demanding applications. They move the rock, haul the trash, deliver the concrete and transport everything from harvested logs to our heavy equipment.  Available in truck or day-cab configurations, the CT660 features a set-back axle with 116-inch and 122-inch bumper to back of cab lengths—providing an extra tight turning radius for enhanced maneuvering.

Introduced in May 2015, the CT680 model Vocational Truck is a Class 8 set-forward-axle model built to tackle today’s most demanding jobs while setting new standards for comfort and style.

The third vocational truck offered by Caterpillar, the CT680 features a rugged exterior, attractive automotive appearance, spacious and ergonomic cab, and vocational-specific engine and transmission. Its set-forward axle, parabolic taper leaf suspension, tuned cab air suspension system, and premium sound insulation and trim combine to deliver industry-leading ride quality.

Powering the CT680 is a Cat CT Series Vocational Truck Engine with horsepower ratings from 410 to 475, peak torque ratings from 1,450 to 1,700 lb-ft and the flexibility to match power and performance to specific jobs and operating conditions. A highly efficient Selective Catalytic Reduction (SCR) solution, with upgraded in-cylinder technology and proven aftertreatment, meets emission requirements.

The CT Series Engine’s durable, compacted graphite iron block reduces weight by as much as 200 pounds compared to standard iron—allowing customers to increase payloads, efficiency and profit. A single Electronic Control Module and fewer electrical connections help reduce diagnostic and maintenance time, and a fluid-free head gasket eliminates the risk of coolant leaking into engine oil or exhaust gases entering the cooling system.

The CT681 model Vocational Truck was introduced in 2014 and has proven to be exactly what truck owners have been looking for in a larger model vocational truck.  A natural extension of the Cat product line, the Cat CT681 Vocational Truck delivers all the power, performance and productivity you expect from Caterpillar. This Class 8 set-forward axle model—ideal for hauling heavy loads—features a spacious and ergonomic cab, industrial styling, vocational-specific engine and transmission options, and bumper-to-bumper support across North America.  If you’re hauling heavy loads or working in extreme conditions, you’ll appreciate the Cat CT681 Vocational Truck’s rugged durability and industrial styling—with the versatility to mount the attachments you need to get the job done.
