All dimensions are approximate. Dimensions will vary depending on the configuration and the options. (A) Overall Width (B) Overall Tire Width (C) Overall Height (body down and empty) (D) Overall Length (E) Loading Height (body empty) (F) Overall Height (body raised) (G) Wheel Base | |
The target gross machine operating weight is listed under "Application/Configuration Restrictions" (see below).
The empty machine weight of the 794 AC 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 extra 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 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 body and high impact liner
- Full tank of fuel
-
75 kg (165 lb) operator
The 794 AC Off-Highway Truck is an earthmoving machine. The 794 AC is classified as a dumper as described in ISO 6165:2012. This machine 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
Application/Configuration Restrictions
The 794 AC Off-Highway Truck cab structure is ROPS certified to ISO 3471:1994 up to
Target Gross Machine Operating Weight for Standard Wheel Stations
The Target Gross Machine Operating Weight (including payload) for the 794 AC Off-Highway Truck equipped with standard wheel stations is
General Operating Restrictions
Use only in a non-explosive gas environment.
| 794 AC Operating Restrictions | Grade |
| Parking Brake Holding Capability(1) | 15% |
| Maximum Side Grade Operation (Except Dumping/Spreading)(2) | 15% |
| Maximum Side Grade for Dumping/Spreading(3) | 0% |
| Maximum Negative Grade (uphill) for Dumping/Spreading(4) | 0% |
| (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 very rapidly during dumping on a side grade. |
| (4) | 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. |
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 machine’s 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.
- Perform machine inspections as described in the Operation and Maintenance Manual and correct any problems discovered.
- Perform system testing as described in the Operation and Maintenance Manual and correct any problems discovered.
- Ensure that machine application conditions comply with Caterpillar’s 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.
