## Komatsu WA800-3 Wheel Loader: A Comprehensive Overview
The Komatsu WA800-3 is a powerful and versatile wheel loader designed for heavy-duty applications in construction, mining, and other industries. With its robust construction, advanced hydraulic system, and innovative features, the WA800-3 delivers exceptional performance and efficiency.
**Engine:**
At the heart of the WA800-3 is a fuel-efficient Komatsu SAA6D170E-6 six-cylinder turbocharged diesel engine. This engine generates a maximum power of 264 kW (354 hp) at 2,000 rpm and a maximum torque of 1,580 Nm (1,163 lb-ft) at 1,300 rpm. The engine's emissions-compliant design meets the latest environmental regulations.
**Transmission:**
The WA800-3 is equipped with a heavy-duty Komatsu 4-speed Powershift transmission. This transmission provides smooth and efficient gear changes, ensuring optimal power delivery for a wide range of operating conditions. The torque converter with lock-up clutch and the fully automatic shift system optimize performance and fuel economy.
**Hydraulic System:**
The WA800-3's advanced hydraulic system delivers exceptional power and control. The variable displacement piston pumps with load-sensing technology automatically adjust the hydraulic flow to meet the demands of the attached implement. This system ensures precise and responsive operation, reducing operator fatigue and increasing productivity.
**Load Sensing System:**
The load sensing system monitors the hydraulic pressure in the attachment cylinders. When the pressure increases, the system automatically adjusts the flow rate from the pumps to match the load demand. This feature prevents hydraulic overload and ensures efficient and precise control of the attachment.
**Attachments:**
The WA800-3 is compatible with a wide range of attachments, making it a versatile machine for various applications. These attachments include:
- Buckets: Standard, heavy-duty, and high-capacity buckets for various material handling tasks.
- Forks: For lifting and handling palletized materials.
- Material Handling Arms: For handling bulky materials such as logs or pipes.
- Grapples: For handling scrap metal or other bulky materials.
**Safety Features:**
The WA800-3 incorporates numerous safety features to ensure operator safety and machine reliability:
- Rollover Protective Structure (ROPS): Provides overhead protection for the operator in the event of a roll-over.
- Falling Object Protective Structure (FOPS): Protects the operator from falling objects.
- Seat Belt: A three-point seat belt ensures operator safety during operation.
- Backup Alarm: Alerts pedestrians and other workers of the machine's presence.
- Emergency Shutdown System: Allows the operator to stop the machine quickly in an emergency.
**Operator Comfort:**
The WA800-3's operator cabin is designed for comfort and productivity. Features include:
- Air-Cooled Seat: Provides comfortable seating for extended periods of operation.
- Suspension Seat: Reduces vibrations and improves operator comfort.
- Digital Display: Provides essential operating information and diagnostic data.
- Joystick Controls: Intuitive and ergonomic joystick controls for effortless operation.
- Air Conditioning: Maintains a comfortable temperature inside the cabin.
**Durability:**
