The Cat® R1600H Underground Loader has a powertrain tuned specifically for speed on grade — mastering poor floor conditions and delivering maximum production in all speed ranges. It has the necessary strength and durability to work in tough conditions, but its precise controls and efficient operation set it apart. It offers superior stability, exceptional digging and lifting, and a variety of efficiency-boosting functions, plus a transmission that delivers constant power. The R1600H also offers a number of safety features, from FOPS/ROPS certified cab and safety glass to the ability to incorporate autonomous operation. Thanks to the extreme durability designed into the structure, the
loader can be productive through up to four rebuilds. The R1600H is an ideal match for the Cat AD30 truck.
