A hydraulic excavator attaches a bucket to achieve the objectives for which it was designed, namely:
 

• Exerting digging forces

• Applying lifting powers

A poorly designed and manufactured bucket affects the whole earthmoving process and reduces productivity.
 

Choosing the right bucket is of paramount importance!!

There are two types of digging forces:

• The breakout force

• The penetration force

When exerted on the cutting edge, the breakout force prevents the bucket from rotating around the pin of the arm by setting in motion the hydraulic cylinder. The breakout force depends on:

• the thrust of the hydraulic cylinder

• the geometric features of the articulated quadrilateral

• the distance between the beam and the cutting edge of the bucket
   

When exerted on the cutting edge and is parallel to it, the penetration force prevents the boom and the bucket from rotating by setting in motion the penetration cylinder. If the thrusts of the hydraulic penetration cylinder and of its lever arm are equal, the penetration force depends on:

• the lenght of the boom

• the position in which the bucket exerts the maximum breakout force

We have developed the ability to choose the right parameters for our buckets, i.e. right distance between the beam and the cutting edge and profiles, thus maximising simultaneously the exert of the breakout force and of the penetration force in good operating conditions. If these two forces are too strong when the bucket is not in the right position to dig, there is a decrease in penetration and digging efficiency (fewer productivity for each litre of fuel). Moreover, these two forces put high stress especially on the linkages, on the front and on the cutting edge of the bucket. It is difficult to detect it, but in most cases this stress results in a local structural failure (linkages, cutting edge, teeth, side plates, etc.).

Our production philosophy has always consisted in manufacturing buckets with a very high penetration efficiency, thus maximising their digging efficiency and their wear life. No other company can ensure a similar degree of reliability. Our efficiency and reliability is shown by the fact that all our products are covered by a two year warranty against structural failures.
