WHY ELECTRIC DRIVE?

Cat® Power Driven Trucks are industry standard and most popular. However, some customers may prefer the drive for specific applications and situations.

100% tracked

Designed and manufactured by Caterpillar, the 795 is the first AC drive that comes from one manufacturer and is supported by the best dealer network in the industry. The 795 transmission works flawlessly with the C-175 engine and provides unsurpassed safety, ease of maintenance and performance.

MODULAR DESIGN FOR EXCELLENT SERVICE

The modular design makes it easy to remove and install components. The motor, generator, motors, inverter, grid and final drives can be removed independently. The rear generator provides better chassis mass balancing and is connected to the engine by an insulated drive shaft, which simplifies generator alignment.

Excellent control gives superior operator confidence

The Cat AC drive system provides industry leading deceleration, braking and control. A class-leading dynamic retardation combined with constant traction control with automatic front brake blending at all speeds gives operators excellent control and confidence.

HIGH VOLTAGE - LOWER HEAT

The Cat AC drive is a high voltage system (2600 V) that operates at relatively low current. As a result, heat dissipation is reduced and the service life of components increases.

CAT AC PROPEL ELECTRIC DRIVE

The C175-16 diesel engine drives the rear alternator through a disconnector. AC power is rectified to a nominal 2600 Volt to form a DC link. The DC line supplies power to the inverter, where the IGBT converts the DC signal to 3-phase AC to drive the traction motors. Engine power drives the wheels through a double gear main drive.

CAT AC ELECTRIC DRIVE WITH RESPECT

When the wheels are slowed down, the motors become generators. Motor power is fed back through the DC channel. Power is supplied to the contactor and breaker circuits, and then discharged through the radial grid. An AC fan blows air through the grill to dissipate power and control the deceleration rate.

GENERATOR / GENERATOR

The 795F traction alternator mounted on the chassis is a three-phase, two-bearing design. The excitation system is brushless, which has longer service intervals than brush-type systems.

INVERTER

The inverter uses Mitsubishi Electric IGBT phase modules to control the traction, direction and speed of the truck. Mitsubishi Electric is a leader in IGBT technology.

TRAFFIC MOTORS

Each traction motor has a three-phase alternating current. High-voltage, low-current motor is installed on the rear axle and is able to work on carts.

RADIAL MESH

The radial grille fits well on deck, providing operators with excellent visibility on the right side. The net has the highest braking capacity in the industry.

VARIABLE COLOR COOLING

The cooling air is provided by a variable flow system that regulates the cooling flow according to the needs of the system. This provides maximum engine power for excellent performance.

ADDITIONAL FEATURES

The mesh drying function quickly dries the mesh in inclement weather. The rollback prevention function prevents the machine from moving in the opposite direction of the operator’s intentions. Grid power is constantly monitored. Mixing the front brakes prevents overheating of the mesh.

CAT® C175-16 ENGINE

The 795F is equipped with an air-cooled four-cylinder diesel engine followed by a Cat C175-16 turbocharged engine that has enhanced power management capabilities for maximum thrust performance in the most demanding mining jobs.

• The C175-16 is a 16-cylinder four-stroke design that uses long effective strokes for maximum efficiency.

• Meets the requirements of the US Environmental Protection Agency.

• A variable speed fan directs maximum power to powertrain, saving fuel when operating conditions allow.

• High displacement, low RPM rating and conservative horse power mean that you spend more time on the roads and less in the store.

• The Cat Common Rail fuel system is an electronically controlled system that determines operating conditions and regulates fuel delivery for optimum fuel efficiency. This precise and flexible fuel system allows the engine to meet emission standards without sacrificing performance, reliability or durability.

• The flexible design of the core of the cooling system offers you a long service life, high durability and ease of maintenance.

• The air start system is serviced at ground level, and the electric start option allows you to completely remove the air system from the truck.

INDUSTRIAL LEADING DYNAMIC DELAY

The radial grid is designed for 4.75 MW (6,365 hp), which allows you to perfectly control the speed of the truck in conditions of a long deceleration. Radial design is lightweight, efficient and quiet.

FOUR COOLED ANGULAR BRAKES FOR ADDITIONAL DELAY

In addition to class-leading dynamic deceleration, Cat oil-cooled four-stage service brakes provide additional stopping power. These are brakes of the same size as the 797. 795 offers exceptional braking without decay and additional braking at all speeds.

CHAIN ​​CONTROL WITH AUTOMATIC FRONT BRAKE CLEARANCE

If the truck detects a slip, the front brakes will automatically engage. Thanks to the additional forward braking, the truck moves in a given direction and the operator is in control. This mixed braking capability is the first in the industry and has been enthusiastically received by the operators. In addition, the operator can choose a constant mixing of the front brakes.

AUTOMATIC DELAY CONTROL

Operator controlled - ARC turns on automatically and constantly maintains speed. A simple toggle switch is used to adjust the slowdown speed.

CONTROL TO PREVENT EXCELLENT ABILITY

Grid Thermal Calculator is built into the software, which constantly monitors the power supply to the network. When the dynamic delay is exceeded, the mechanical brakes apply automatically. This will continue as long as necessary. Often this is a transitional state. The operator is alerted to the need for corrective action if this continues. Mixing of brakes occurs smoothly and smoothly.

BRAKE CONSTRUCTION

Cat oil cooled brakes are designed with large discs and plates for reliable and smooth operation. They are closed and closed to prevent pollution and ensure a long service life.

HAND BRAKE

A water-cooled parking brake with spring-loaded hydraulic release on all wheels provides excellent parking ability on slopes up to 15%.

ANTI-ROLLBACK

Automatically applies service brakes to prevent the vehicle from moving from a stop opposite to the intended direction of travel.

DELAYED REVERSE SHIFT
