Преимущества и особенности
EASY TO OPERATE
- Updated cab, with an Integrated Roll Over Protection Structure (ROPS), gives operators greater all around visibility to enhance safety and productivity.
- Quieter interior, with improved pressurization, helps keep dust out for a cleaner operating environment.
- Pilot hydraulic implement controls reduce operator effort and offer more consistent, precise and responsive operation.
- Single handle control for all direction and gear selection.
- Tiller bar control allows the operator to work more precisely in close areas.
PERFORMANCE AND PRODUCTIVITY
- Cat 3406 engine allows the D8R to doze through tough material.
- Differential Steering maintains full power to both tracks for best-in-class turning, even with a full blade load.
- Load Sensing Hydraulics continuously adjust hydraulic power to maximize your efficiency; dedicated implement pump ensures adequate available hydraulic power.
- Advanced Modular Cooling System has excellent cooling capacity with increased air flow, allowing the machine to work in the most demanding environments.
BUILT FOR LONG TERM PRODUCTION
- Caterpillar elevated sprocket design isolates final drives from ground induced impacts.
- Suspended undercarriage provides a smooth ride and better traction in uneven terrain.
- More than 35 years of experience with elevated sprocket/suspended undercarriage design.
LOWER MAINTENANCE COSTS
- Features like grouped service points, sight gauges, fast fuel fill and easy engine compartment access help make regular maintenance faster and more convenient.
- Field proven mechanical engine features a modular design for ease of service.
- Modular transmission components offer easy service access.
- Individual radiator cores can be quickly replaced for ease of service.
- Product Link™/VisionLink® connects owners to their equipment, providing access to machine data such as location, hours, and event codes.*
- Certified rebuild* and remanufacturing* options to help you save on lifetime owning and operating costs.
* Not available in all areas. Please consult your Cat dealer.
PURPOSE BUILT SPECIALTY MODELS
- D8R desert arrangement offers a package of options ideally suited to enhance machine performance in extremely sandy or abrasive underfoot conditions.
- Copper nickel core radiator for added cooling performance.
- Specially coated fan and radiator help resist abrasion.
- Core protection grid.
- Sealed bottom guard and added seals to help keep fine abrasive particles out of components.
- Optional wear plates can be replaced to give you longer blade life when working in abrasive conditions.
- D8R Waste Handler is ideally suited for building or closing cells, pushing trash or spreading cover.
- Specialized guarding, striker bars and seals help protect the machine from impact and airborne debris.
- Bottom and final drive guarding help prevent debris from wrapping around or damaging vital components.
- The cooling system is designed for high debris environments, with easy access for cleanout.
- Lights are mounted up and away from main debris area for protection, while still giving you plenty of light on the work area.
- Specialized air intake precleaner helps deliver cleaner air to the machine.
- Landfill blades and trapezoidal-hole track shoes help you optimize your waste handler for the job.
