User manual CATERPILLAR 795F AC BROCHURE

[. . . ] A sight level gauge replaces the dip stick. 3 Power Train ­ Cat AC Electric Drive More power to the ground for greater productivity. Why Electric Drive? Cat mechanical drive trucks are the standard of the industry and are favored in most applications. Some customers, however, prefer electric drive for specific applications and situations. 100% Caterpillar Designed and manufactured by Caterpillar, the 795 is the first AC electric drive truck that is single sourced from one manufacturer and supported by the best dealer network in the industry. The 795 power train works seamlessly with the C-175 engine and offers unsurpassed Safety, Serviceability and Performance. Modular Design for Excellent Serviceability The modular design allows ease of component removal and installation. The engine, generator, motors, inverter, grid, and final drives can be removed independently. [. . . ] The 795 offers exceptional non-fade braking and supplemental retarding at all speeds. Traction Control with Automatic Front Brake Blending If the truck senses any slip ­ the front brakes will automatically engage. The addition of front braking keeps the truck moving in the intended direction and the operator in control. This blended braking capability is an industry first and has been enthusiastically received by operators. In addition, the operator can select full time front brake blending. Automatic Retarding Control Operator controlled ­ ARC engages automatically and maintains speed consistently. A simple toggle switch is used to adjust retarding speed. Parking Brake The oil cooled, spring applied, hydraulically released parking brake on all wheels provide superior parking capability on grades up to 15%. Control to Prevent Exceeding Retarding Capability Built into the software is a Grid Thermal Calculator that constantly monitors power to the grid. When dynamic retarding capability is exceeded the mechanical brakes are blended in automatically. This will continue as long as necessary. Often this is a transient condition. The brake blending is smooth and seamless. Anti-Rollback Automatically applies service brakes to prevent the truck from rolling from a stop opposite the intended direction of travel. Reverse Shift Inhibit Ensures reverse propulsion is not applied when the machine is moving forward. Brake Design Cat oil cooled brakes are designed with large discs and plates for reliable and adjustment free operation. They are enclosed and sealed to prevent contamination and provide long life. 7 Structures Building on the legacy of superior, long life structures. Box Section Design The 795F AC uses a box-section design, incorporating forgings and castings in high stress areas with deep penetration, continuous wrap-around welds to resist fatigue from racking loads. · Steel Structures ­ Mild steel used throughout the frame provides flexibility, durability and resistance to impact and allows for field repairs with common weld practices. · Castings ­ Large radii castings dissipate stress in areas of high stress concentration. Castings allow welds to be placed in lower stress areas for longer frame life. Integral Four-Post ROPS Cab Resiliently mounted to the main frame to reduce vibration and sound, the integral ROPS cab is designed as an extension of the truck frame. Suspension System Designed to dissipate haul road and loading impacts for longer frame life and a more comfortable ride. · · Durable Design ­ Large diameter cylinders with nitrogen over oil design for long life and minimal maintenance. Front Cylinders ­ Have preset caster and camber and are mounted to the frame. They also serve as steering king pins for a tight turning radius. · Rear Cylinders ­ Allows axle oscillation and absorb bending and twisting loads from the haul road isolating them from the main frame. Four-Bar Link Rear Suspension Directs a more even load distribution into the main frame ­ operators report a more secure feeling of the truck being well connected and under control. Steering System Single tie rod steering system is simpler and requires less maintenance. 8 Truck Body Systems Cat Bodies for Cat Trucks Caterpillar designed and built for rugged performance and reliability. Integral to the truck the body is designed to fit with the chassis and work as part of the truck system. This shows a strong commitment to operator and operational safety. Ergonomic Cab Layout Controls are intuitive and within easy reach making the operator more comfortable, productive and safe. Operator feedback for the 795 is easy to learn and easy to control. Viewing Area The large viewing area offers exceptional visibility, allowing the operator to drive with confidence for high productivity. The right hand platform is free of obstructions for a clear view. 1) Air suspension seat with three-point operator restraint 2) Hoist lever 3) Secondary brake pedal 4) Advisor display 5) Adjustable steering column 6) Vehicle directional control 7) Gauges 8) Storage compartment 9) Full size trainer seat 10) Electric powered operator window 11) Turn signal and wiper controls 12) Ventilation controls 13) Four post ROPS 14) Cat Detect monitor 15) MineStar Monitor (optional) 16) Cup holder 17) Dome lights 11 Customer Support Best dealer network with best service and parts support.
