Elevator Mechanism

The elevator mechanism conditions material as it works, lifting material off the cutting edge and carrying it to the top of the load for true self-loading capability. The 623G is ideal for windrowing, blending material as well as breaking up vegetation in stripping operations.

Scraper Bowl

Caterpillar Scraper bowls deliver large loads with better retention, excellent material flow, fast cycle times and high productivity. Relocating the implement valve to the draft tube improves access and serviceability.


The latest electronic monitoring systems, grouped service points, and rugged Caterpillar components simplify maintenance and minimize downtime. New two-piece access doors open easily and stay open for better access.


Superior structural design delivers state-of-the-art ride, capacity, and material control while assuring the durability and reliability customers expect from Caterpillar.
