The 70Z7 sports a 173 hp (gross) Cummins engine, a ZF five-speed transmission, work mode selector, 50-degree bucket tilt-back angle for carrying, and a full turn tipping load of 22,800 lbs. (10,342 kg).
Like all the new Z7 wheel loaders, Kawasaki’s 70Z7 has retained the IntelliTech functions such as the patented IntelliDig system, balancing rim pull force and hydraulic digging force to match conditions, the QuickCycle function, and the FlexShift feature, which matches shift points to the actual working conditions. But unlike its larger-sized classmates, the 70’s intelligence works behind the scenes, so many of its operations perform without human intervention. The 70 also is incredibly easy to run with a high-intensity LCD monitor, straightforward dash arrangement, and intuitive systems, which make it ideal for rental purposes as well as operations where operator skills run the spectrum, according to the manufacturer.
New TIVi emissions technology means a more fuel-efficient and savvy loader. The 70Z7 has reduced fuel usage considerably over the previous generations in this size class.
When it comes to power, the 70Z7 has it by the bucketful. It sports a 173 hp (gross) Cummins engine, a ZF five-speed transmission, work mode selector, 50-degree bucket tilt-back angle for carrying, and a full turn tipping load of 22,800 lbs. (10,342 kg). A Quick Power switch kicks in enough extra power to muscle through momentary tough spots, or in very challenging environments the power mode can be selected, although field tests show it isn’t required for even the most demanding applications.
The 70Z7 also is quite versatile. Add a high lift arm configuration, or third spool hydraulics to that and the 70Z7 can handle a variety of applications and environments, according to the manufacturer.
Home Away From Home
In the cab, there’s improved visibility especially to the rear, ample air conditioning and heat, and lots of storage. Pressurization reduces dust infiltration. Tilt telescoping steering, bolt-on adjustable side console, air suspension seat, and AM/FM/CD/WB radio with AUX input means anyone can feel right at home and the multifunction single-control lever simplifies tasks. The direct acting orbitrol steering responds quickly and accurately, minimizing operator effort.
The 70Z7 also was designed with ease of maintenance in mind. The change to TIVi also means the 70 has no diesel particulate filter (DPF). The adapted EGR technology reduces NOX and particulate matter. The automatic reversible cooling fan, along with the diesel fuel cooler, takes the worry out of heat and dust build-up as well.
Gull-wing doors provide easy access to the engine. Rear operational lights are safely tucked into the bumper/counterweight. The hydraulic oil-change service interval is extended up to 4,000 hours when KCM SuperEX46 fluid is used. The engine-oil service interval is extended to 500 hours with the use of low-ash CJ-4 oil. And the HN bushings, located throughout the front end of the loader, extend lubrication to 500 hours. HN bushings have high-viscosity oil vacuum-impregnated into sintered high-hardness metal. During machine operation, that oil oozes from the pores of the bushing into the clearance between pins and bushing. HN bushings are located in the following pins: bucket, bucket link, bucket cylinder, bell crank, lift arm cylinder, lift arm pivot, and steering cylinder.
