Failure to comply to the rated load can cause possible personal injury or property damage. Review the rated load of a particular work tool before performing any operation. Make adjustments to the rated load as necessary for non-standard configurations. |
Note: Rated loads should be used as a guide. Work tools, uneven ground conditions, soft ground conditions, or poor ground conditions have effects on rated loads. The operator is responsible for being aware of these effects.
Rated loads are based upon a standard machine with the following conditions:
- proper lubricants
- full fuel tank
- enclosed ROPS
- 75 kg (165 lb) operator
- 29.5x29 34PR L-5 tires or equivalent for the R2900G Load Haul Dump
- 35/65 R33 Two Star L-5 tires or equivalent for the R2900G XTRA Load Haul Dump
Rated loads will vary for different work tools. Consult your Caterpillar dealer about the rated load for specific work tools.
The rated operating load is defined by the ISO 5998 ( 1986) standard as 50 percent of the full turn static tipping load.

Dimension (A) represents the dump clearance. Dimension (B) represents the reach. |
The dump clearance and the reach are given for each bucket at maximum lift height and at a 45 degree dumping angle. Dump clearance (A) is measured from the ground to the bucket edge when the bucket is in the full DUMP position. Reach (B) is measured from the front of the front tire to the bucket edge when the bucket is in the full DUMP position.
The following table provides the rated operating load for the standard machine configuration.
