K-Tec has attached its line of large earthmoving scrapers to 40-tonne articulated dump trucks (ADTs) since 2008; the 28 cubic yard scraper has been one of K-Tec’s most popular models for several years. But this has now been reconfigured to mount onto 25- and 30-tonne ADT chassis in addition to tractor units.

ADTs can be converted to pull a K-Tec 1228ADT for a unit that can self-load, transport, and eject material with a single engine running and a solitary operator.

The operator controls the scraper using a joystick inside the ADT cab. A K-Tec digital display in the cab shows operating details, load count productivity, and troubleshooting.

K-Tec reckons this improves the productivity and versatility of the ADTs. The 1228ADT scraper is able to self-load for precision grading and dumping; be push-loaded for enhanced loading time; or be top-loaded via excavator for heaped hauling.
