BUCKET SELECTION CHART


The choice of bucket is determined by the density of the material and the expected bucket fi ll factor. The actual bucket volume is often larger than the rated
capacity, due to the TP Linkage features:

• Open bucket design.

12.JPG

13.JPG

• Very good roll back in all positions.

• Good bucket fi ll performance. The below example and table
are intended for Standard boom. Example: Sand and gravel. Fill factor ~ 105%. Density 1,65 t/m3. Result: The 3,3 m3 bucket carries 3,5 m3. For optimum
stability always consult the bucket selection chart.
