New 85Z7 and 90Z7 Wheel Loaders Released
Mar. 27, 2012
90Z7
Tokyo, March DD, 2012— KCM Corporation, a Kawasaki group company, announced today that it will launch its new 85Z7 and 90Z7 wheel loaders, compliant with the U.S. Tier 4 Interim emission standards, in the North American region on April 1.
The 85Z7 and 90Z7 were 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 new models redefine the wheel loader in its every aspect—including safety, cost performance, operational performance, exterior design and operator comfort—to deliver a product that satisfies varying levels of user needs in the global market.
The 85Z7 and 90Z7 significantly reduce air-polluting NOx and PM exhaust emissions to meet the latest Tier 4 Interim emission standards* mandated in the U.S. They 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.
*New emission standards for nonroad diesel engines set by the U.S. Environmental Protection Agency, covering most of the construction, agricultural and industrial machinery.
The features and main specifications of the 85Z7 and 90Z7 are outlined below.
Key Features
Tier 4 Interim Emission Standards Compliant
| ･ |
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 90% 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. |
Through these new systems and control mechanisms, a fuel saving of 10-20% is accomplished compared to existing models.
Improved Operating Performance, Safety and Ride Comfort
| ･ |
A comprehensive package of various new control mechanisms—the IntelliTech System—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. |
