New additions to the Cat backhoe loader line-up, the 440 and 450 center pivot models, provide industry-leading lifting performance, high breakout forces and improved operating comfort and ergonomics.
Cat 440 boasts a 25-percent backhoe lifting improvement over the 430F2 and 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 an all-new cab for increased operator comfort.
Lift and tilt breakout forces have also significantly increased on both the 440 and 450 for greater machine productivity. A more balanced weight design and longer backhoe stabilizer legs improve operating stability. The new stabilizer systems can be equipped with available guards to prevent damage to the cylinder rod, and optional leg plate guards prevent material build-up on the underside of the stabilizer leg.
Both models’ powertrains are anchored by the Cat C4.4 ACERT engine that meets stringent Tier 4 Final emissions levels and uses a service-free SCR solution for improved operating efficiency. The standard Autoshift transmission features a sixth gear for improved roading performance and optional Lock Up Torque converter for more torque and efficiency on grades. New spring-applied hydraulically released (SAHR) brakes provide simplified operation of the parking brake.
A completely reengineered hydraulic infrastructure for the operator station features seat-mounted controls to deliver a more comfortable operating position, reducing operator fatigue over extended shifts. Electronic sensors imbedded in the new design automatically detect the seat position. The controls stay with the operator regardless of forward or reverse operation and eliminate the pilot control pods for backhoe operation, significantly increasing legroom at the rear of the cab. •
