Kawasaki Launches 6 New Wheel Loader Models Compliant with 2011 Emission Standards
Mar. 04, 2013
Tokyo, March 4, 2013 — KCM Corporation, a Kawasaki group company, announced today that starting on April 1, it will launch six new wheel loader models for the Japanese market — 80Z7, 85Z7, 90Z7, 92Z7, 97Z7, 115Z7 — that meet the 2011 emission standards targeting non-road special motor vehicles*1.
The new line of wheel loaders, called the Z7 series, was developed jointly by KCM and Hitachi Construction Machinery Co., Ltd., combining the expertise of the two companies. While preserving the merits of existing models, the Z7 series redefines the wheel loader in its every aspect to satisfy varying levels of user needs, including safety, cost performance, operational performance, exterior design and operator comfort.
The Z7 series significantly reduces air-polluting NOx and PM exhaust emissions to meet the 2011 emission standards for non-road special motor vehicles established by the Ministry of Land, Infrastructure, Transport and Tourism. The new wheel loaders also come equipped with a new hydraulic control system and engine output control mechanism, which reduce fuel consumption by 10-20% while greatly improving operational performance.
- *1
- New diesel engine emission regulations targeting non-road special motor vehicles (nearly all construction, agricultural and industrial machinery).
The features and main specifications of the Z7 series are outlined below.
Key Features
Compliant with 2011 Emission Standards for Non-road Special Motor Vehicles
- The engine comes loaded with new features such as the diesel particulate filter (DPF), exhaust gas recirculation (EGR) system, and variable geometry turbocharger (VGT), which combine to reduce NOx and PM emissions by approximately 50% and90% respectively compared to existing models.
Reduced Fuel Consumption
- The Open Center Load Sensing System, a simple and highly maneuverable system using a variable displacement pump, minimizes hydraulic energy loss during operation.
- The engine features a new control mechanism that optimizes energy consumption.
- Optimal arrangement of equipment, high-performance hybrid fan, and control mechanism that optimizes rotation speed according to the vehicle status combine to reduce the energy required to operate the cooling fan.
- The 97Z7 and 115Z7 feature a torque converter with a lock-up clutch that reduces fuel consumption by transmitting the engine output directly to the transmission when operating at high speeds.
Through these new systems and control mechanisms, a fuel saving of 10-20% is accomplished compared to existing KCM models.
Improved Operating Performance, Safety and Ride Comfort
- An integrated system of various new control mechanisms dramatically improves performance and efficiency in the full range of applications from digging to hauling and loading.
- The instrument panel in the operator's seat employs a high-resolution full color liquid crystal display for easy viewing. A built-in rear view monitor offers clear visibility when backing up the vehicle.
- An inclined ladder was adopted for safer access to the cab, along with improvements in the cab door and handrail.
- With a cab that is more spacious and airtight, the new wheel loaders promise greater ride comfort.
Exterior Design that Aspires to Functional Beauty
- The exterior employs a dynamic design that makes liberal use of three dimensional curvilinear surfaces, while securing a clear field of vision for the operator.
New Maintenance Package
- KCM will launch a new-vehicle warranty program designed for the Z7 series.
- The warranty period for the power train (main components including the engine, transmission and hydraulic equipment) is extended to either three years or 5,000 hours of service, whichever comes first*2.
- Free maintenance services
Free replacement of engine oil and engine oil filters is offered every 500 hours up to four times.
After 4,500 hours of operation, KCM will clean the muffler filter free of charge.
- *2
- A paid maintenance service agreement needs to be concluded to receive warranty coverage after twelve months.
