Cat 623K Wheel Tractor Scraper

Cat announced that its new 620 K Series wheel tractor-scrapers—the 621K, 623K and 627K—offer features such as high-pressure steering, engine overspeed protection, tire spin reduction, differential lock engagement protection, machine/ground-speed control and payload estimator. Payload capacity of the open-bowl 621K and open-bowl, twin-engine 627K is 28.8 tons (26.2 mt), and 27.6 tons (25.1 mt) for the elevating 623K.

The new models incorporate a number of enhancements: Advanced Cushion Hitch uses new software to dampen end-of-stroke movement of the load cylinder for a smoother ride; hydraulic-system refinement simplifies the bowl quick-drop function; draft arm overflow guards divert material away from bowl sides; Auto-Stall assists in quickly bringing the transmission to operating temperature for faster transitions from torque-convertor drive; cab interiors feature a redesigned dash as well as visibility and operator comfort enhancements; maintenance improvements include an easier-to-service filter bank; and the Fuel Economy Mode for the 627K adjusts shift points and power distribution for optimum fuel economy.
