Waste Handler Track Loaders

We build the most complete line of track loaders in the construction equipment industry. Matching Cat® track loaders to specific applications is easy with several different configurations of track loaders built to serve customers worldwide.

973D Waste Handler

Caterpillar built its first track loader in 1955. With its pedigree for digging, the track loader has excavated millions of building foundations all over the globe. It wasn’t long before customers demanded that the strength and versatility of this machine be adapted to the forestry, demolition, steel mill and waste industries. With Caterpillar built and designed waste handling features, the track loader is now considered the second most useful machines in a landfill (after the compactor). The Cat® 973D is the largest, most powerful track loader in the world, and it’s the safest, most environmentally friendly and efficient track loader Caterpillar has ever built. Put it to work in waste, it’s designed for it. Read on for more information on the 973D’s waste handling attributes, and how they can benefit your operation.
