Industry Leading Dynamic Retarding

The radial grid is rated at 4.75 MW (6,365 hp) - allowing you excellent control of the truck speed in long retarding applications. The radial design is light, efficient and quiet.

Four Corner Oil Cooled Brakes for Additional Retarding

In addition to class leading dynamic retarding - Cat four corner, oil cooled service brakes give additional retarding capability. These are the same sized brakes used on the 797. 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.

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 operator is alerted to take corrective action if this continues. The brake blending is smooth and seamless.

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.

Parking Brake

The oil cooled, spring applied, hydraulically released parking brake on all wheels provide superior parking capability on grades up to 15%.

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.

Cat Bodies for Cat Trucks

Integral to the truck the body is designed to fit with the chassis and work as part of the truck system. Each body is sized to meet the payload requirements without compromise to vehicle balance, braking or control.

Cat Body Choices

Body options include the popular MSD II (Mine Specific Design) and Gateless Coal Bodies. Liner options fit the body to the application.

• MSD II Body - Based on the mine site evaluation of your mine, the body is sized and configured to meet the specific needs dictated by fragmentation, abrasion, cohesion, and the loading tool. This body achieves an excellent balance of payload and durability.
