New Cat Loader and Mining-Class Excavator: Redesigned from the Ground Up

摘要

Caterpillar's Global Mining group recently previewed two new earthmover models for the trade press at its training, demonstration and testing site near Tucson, Arizona. One is an all-new version of the 994 wheel loader, the flagship of the Cat loader line for 25 years; and the other, a 250-ton-class hydraulic excavator that began as a concept at a competing company but will enter the market as a clean-sheet, Cat-designed machine with full dealer support. The 994K loader, successor to the 994H, is more than 6 ft (2 m) longer and, at 527,218 lb, roughly 88,000 lb (40,000 kg) heavier than the older version-but Cat didn't just pile-on extra iron to achieve these measurements. The K version is a redesigned unit that uses its larger mass and higher breakout force to become "...not just a loader, but a good digger," according to Cat Product Specialist Randy Aneloski.
