Undercarriage systems for construction excavators

A medium excavator is an earthmoving machine that travels slowly and short distances. Its undercarriage moves for 10-20 % of SMU (Service Meter Unit) hours. Typically used on construction sites, this type of excavator is the ideal choice for many projects that require lifting or transporting large materials. As excavators for construction have high machine weight and high impact on the undercarriage during normal working conditions, Berco undercarriage parts for excavators offer remarkable wear-resistance, protecting the components from moisture, impacts and abrasion.
