Kawasaki's two new compact wheel loader models include the 42ZV-2, a 0.78-yd³ (21-ft³) loader, and the 1.18-yd³ (32-ft³) 45ZV-2, both "designed and engineered with all of the performance and reliability of the larger Kawasaki wheel loaders, but in a smaller package."
With Tier 4 Interim emissions-compliant Kubota engines and heavy box frames, the machines provide stable, reliable operation. HN bushing technology, easy-access electrical relays, and a side-by-side aluminum radiator and oil cooler provide for ease of maintenance.
Both loaders are fitted with four-cycle, watercooled direct-injection engines, with the 42ZV-2 offering 45.7 hp (34 kW) at 2400 rpm and the 45ZV-2 offering 63 hp (47 kW) at 2200 rpm. The bore and stroke of the 42ZV-2 is 3.43 x 4.03 in (87 x 102.4 mm) and 3.7 x 4.72 in (94 x 120 mm) for the 45ZV-2.
With what is described by the company as a "walk-through cab design" and easy-read monitors, the operator-friendly wheel loader also features a rubber-mounted ROPS/FOPS cab engineered to reduce noise and vibration, a suspension seat, and pillar-less full length windows.
With one of the highest ground speeds in its class, the 45ZV-2 features an electronically controlled hydrostatic powertrain providing quick, smooth acceleration and deceleration. The wrap-around counterweight lowers the center of gravity, contributing to improved stability.
Standard on the 45ZV-2 is Eco Mode, which Kawasaki says provides a fuel-efficient setting that results in better fuel economy without affecting productivity.
Also straight off the Kawasaki drawing board is its new 65Z wheel loader, its first entry into the hybrid market.
There is no oil-filled torque converter in the 65Z. Through the use of HYTCs (hybrid torque converter system), the loader not only saves power but regenerates energy during idle and braking.
During the initial acceleration or idle periods, energy loss generated in the torque converter is converted to electric energy and then stored in the capacitor. The capacitor will charge and discharge electric energy instantaneously rather than the delayed delivery of a conventional battery. The stored energy is then used by the motor/generator to assist the engine, therefore requiring a smaller engine and resulting in fuel savings.
The release date on the 65Z hybrid loader for the North American market has not yet been announced.
