CATERPILLAR has introduced a new handler designed to handle greater payloads in aggregates yard applications.
The new 990K aggregates handler is capable of offering as much as a 25% payload increase compared to the standard model, according to Cat.
The handler offers a 20-tonne payload and a full turn static tipping load of 43,738 kg. Machine stability is supported by an additional counterweight while “robust” 990K structures ensure durability in the aggregate handler configuration, the manufacturer said.
The 990K is available in standard lift configuration with 13.5 ft. dump clearance and in high lift configuration with 15 ft. dump clearance. Increased capacity and dump clearance is said to enable customers to load railcars and large trucks with a better pass match for faster material handling at lower cost per ton.
The aggregate handler is built on the features of the 990K wheel loader. A Cat C27 engine delivers net power of 699hp (521kW). A lower engine speed is described as helping drive economical fuel use. ECO mode (on-demand throttle), engine-idle shutdown system and engine-idle kickdown/auto-resume system are also said to provide additional fuel savings.
The Cat impeller clutch torque converter uses a lock-up clutch, which Caterpillar describes as providing direct drive to boost fuel economy, trim cycle times and reduce heat. The system is said to allow operators to balance rimpull and hydraulic power for optimum loading efficiency. Positive flow control implement hydraulics use a variable displacement pump to apportion oil flow based on operator control inputs.
The operator station features the Cat Vital Information Management System – VIMS 3G – which provides customisable profiles, a cycle timer and a payload control system. The 990K is also equipped with the Cat Vision rear view camera and in-cab display. The optional Cat Detect object detection system builds on the camera system with radars and in-cab software that provide notification to the operator when an object is detected within the radar coverage area.
