313B CR Excavator Caterpillar

This machine can be equipped with a large variety of boom-stick-bucket combinations in order to meet the needs of various applications.

As a general rule, use a bucket with a smaller capacity when you are using a longer stick and/or a longer boom. Conversely, use a bucket with a larger capacity when you are using a shorter stick and/or a shorter boom. This rule ensures better machine stability and protection against structural machine damage.

Table 1 shows various compatible boom-stick-bucket combinations. Select an optimum combination according to the working conditions and according to the type of work that is being done.
