The ROBUSTUS from Berco includes the Berco pin retention system

The ROBUSTUS from Berco that includes the Berco pin retention system lowers dozer undercarriage wear and improves operator comfort.

The concept is based on a concept where the bushing fully rotates around the sprocket, according to the Italian company which is part of the Thyssenkrupp group and a major first tier supplier of undercarriages to global construction equipment manufacturers.

ROBUSTUS – ROtating BUShing Track Undercarriage System – allows the bushing to rotate separately from the linkage system to dramatically lower wear of the bushing and sprocket. The system requires the Berco pin retention system, reinforced bolts and nuts and improved seal design. The resulting increased stability translates into more comfort for the operator because of less noise and fewer vibrations.

The company estimates that undercarriage lifetime can be extended up around 35%, with up to 6,000 hours of dozer operation with no maintenance. This could translate into a cost saving of 25%. ROBUSTUS us recommended for highly abrasive soil conditions.
