The target gross machine operating weight is listed under "Application/Configuration Restrictions" (see below).
The empty machine weight of the 797F will depend on the configuration of the machine. Weigh the empty machine to get an accurate weight. If a suitable scale is not available, contact your local Cat dealer for an approximate weight of the machine, as equipped when shipped from the factory. This weight will not include additional equipment or options that have been installed on the machine after leaving the factory.
The target payload depends on the machine configuration. To calculate the target payload, subtract empty machine weight from the target gross machine operating weight.
The Caterpillar payload overload policy, referred to as the 10/10/20 Overload Policy, states that no more than 10% of payloads may exceed 110% of the target payload, and no single payload shall ever exceed 120% of the maximum target payload.
If the autonomous system is equipped, the autonomous system is designed to derate the machine to 11.5% of the speed it would have been traveling if nominally loaded when overloaded 110-120% of Truck Target Payload Weight and to 15 km/h (9 mph) if the payload is greater than 120% of Truck Target Payload Weight. The Truck Target Payload Weight should be set as outlined by the procedure in the Operation and Maintenance Manual, M0082032, Specifications, Weights section.
If this machine has a "CE" plate that is required for the European Union, the weight on the "CE" plate is based on the following:
- Empty machine weight with a flat floor body and high impact liner
- Full tank of fuel
-

The 797F Off-Highway Truck is an earthmoving machine. The 797F is classified as a dumper as described in ISO 6165:2006. This is a self-propelled wheeled machine with a rigid frame and wheel steering. This dumper has an open body that is intended for the following applications: transporting loose material and dumping loose material
Specified Useful Life or Expected Life
The specified useful life, defined as total years of operation, or expected life, defined as total machine hours, of this machine is dependent upon many factors including the machine owner’s desire to rebuild the machine back to factory specifications. Consult your Cat dealer for assistance in calculating overall owning and operating costs required to determine the machines specified useful life or expected life. The following items are required to obtain an economical specified useful life or expected life of this machine:
- Perform regular preventive maintenance procedures as described in the Operation and Maintenance Manual, M0082032.
- Perform machine inspections as described in the Operation and Maintenance Manual, M0082032 and correct any problems discovered.
- Perform system testing as described in the Operation and Maintenance Manual, M0082032 and correct any problems discovered.
- Ensure that machine application conditions comply with Caterpillar recommendations.
- Ensure that the operating weight does not exceed limits set by manufacturer.
- Ensure that all frame cracks are identified, inspected, and repaired to prevent further development.
Application/Configuration Restrictions

General Operating Restrictions
Use only in a non-explosive gas environment.
| 797F Operating Restrictions | Grade | Autonomous Grade Restrictions |
| Parking Brake Holding Capability(1) | 15% | 15% |
| Maximum Side Grade Operation (Except Dumping/Spreading)(2) | 15% | 10% |
| Maximum Side Grade for Dumping/Spreading(3) | 0% | 5%(4) |
| Maximum Negative Grade (uphill) for Dumping/Spreading(5) | 0% | 0% to 10%(6) |
| (1) | The listed restriction assumes that the brake components are within working specifications, the machine mass is at maximum allowable, a graded ground surface, and a dry, firm underfoot. The machine operator is responsible for evaluating the condition of the machine, the environment, and use appropriate judgment to maintain control of the machine. |
| (2) | Operating on a side grade is not recommended. The listed restriction assumes a machine operating perpendicular to a side grade, graded ground surface, nominal payload, homogeneous payload distribution in the bowl, and operating on dry, firm underfoot. Refer to Operation and Maintenance Manual, "Slope Operation" for more information. |
| (3) | Dumping on a side grade is not recommended. The center of gravity of the machine changes veryrapidly during dumping on a side grade. |
| (4) | Dumping at 45 degree angle on up to a 10% (+/- 2%) uphill grade is allowed. This feature allows up to a 5% cross grade restriction. |
| (5) | Trucks are designed to dump on level ground with some variation in underfoot surface conditions. Dumping while machine is on a negative grade is not recommended because under some conditions, variations in payload densities and payload discharge characteristics could result in the front wheels lifting off the ground. |
| (6) | 0% allowed for negative grade dumping and 10% allowed for positive grade dumping. |
