Equipment Overview

The CAT 623 is an elevating scraper built for self-loading haul-and-spread work, sitting at the top of Caterpillar’s elevating scraper range above the 613 and 615. It has a heaped capacity of 17.6 cubic metres and an empty operating weight of close to 40 tonnes, suited to larger subdivision and commercial site earthworks, quarry and aggregate site preparation, and topsoil stripping on land development projects where an elevator’s fine-grading ability still matters.

A Cat C13 engine drives the tractor, producing 304 kW (407 hp) at 2000 rpm and meeting emission levels equivalent to U.S. EPA Tier 2/EU Stage II or U.S. EPA Tier 3/EU Stage III. Power runs through an eight-speed planetary powershift transmission with APECS engine-transmission matching software, and only the tractor’s rear wheels are driven; the scraper axle trails on its own wheels behind the bowl.
