Cat introduced two new backhoe loaders to its lineup: the 440 and 450.
The center pivot models feature increased lifting performance and breakout forces and improved operating comfort, according to the company.
The 440 boasts a 25 percent backhoe lifting improvement over the 430F2, as well as redesigned single-tilt loader arms, providing parallel lift and versatility in a multitude of applications. The new 450 offers 15 percent higher backhoe lifting capacity than the 450F and introduces a new cab.
A more balanced weight design and longer backhoe stabilizer legs improve operating stability, Cat said. The new stabilizer systems can be equipped with available guards to prevent damage to the cylinder rod, and optional leg plate guards prevent material buildup on the underside of the stabilizer leg.
The powertrains for both models are anchored by the Cat C4.4 ACERT engine, which meets Tier 4 Final emissions standards using a service-free SCR solution.
The standard Autoshift transmission features a sixth gear for improved roading performance, and an optional lock-up torque converter improves torque and efficiency on grades. Spring-applied hydraulically released brakes provide simplified operation of the parking brake.
The machines also feature seat-mounted controls; electronic sensors imbedded to automatically detect the seat position; and soft keys for fast and efficient setting of machine settings. The controls stay with the operator regardless of forward or reverse operation and eliminate the pilot control pods for backhoe operation.
Full text diagnostic descriptions and instruction pop-ups aid in efficient machine operation and troubleshooting. Up to 25 different user codes can be stored in the new models for operating security and quick pattern changes.
Electrical sensors positioned at the tilt and lift arm enable parallel arm movement for increased material retention when lifting the loader bucket and safe handling of palletized loads. In-cab programmable kickout allows the operator to quickly establish upper and lower arm positioning, and return-to-dig limits can be set for efficient loader material excavation.
The 440 and 450 models can be ordered from the factory or field retrofitted with the optional loader quick coupler that delivers quick work tool changes and increased machine versatility using the Cat Integrated Tool Carrier system. These new backhoe loaders also feature adjustable auxiliary hydraulic flow to the work tool.
The new 440 and 450 backhoe loaders come standard with Product Link systems that transmit critical machine operating data via VisionLink back to the office.
