Failure to comply to the rated load can cause possible personal injury or attachment damage. Review the rated load of a particular attachment before performing any operation. Make adjustments to the rated load as necessary. |
Note: Rated loads should be used as a guide. Attachments, 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
-
80 kg (176 lb) operator - 45/65-45 tires or equivalent
Rated loads will vary with different attachments. Consult your Caterpillar dealer about the rated load for specific attachments.
The rated operating load is defined by SAE "J818" (May 1987) and by ISO 5998 (1986) as 50% of the full turn static tipping load.

The dump clearance and the reach for a standard lift machine are given for each bucket at maximum lift height and at a 50 degree dumping angle. Dump clearance (A) is measured from the ground to the bucket edge. Reach (B) is measured from the front of the front tire to the bucket edge.
The following table provides the rated operating loads for the standard machine configuration with a bucket.
