Medium bulldozer undercarriage components

Undercarriage systems for construction dozers

Dozers for construction sites travel at long distances and high speeds, to a maximum speed of approx. 10-12 km/h. Hence, the UC of these machines requires a larger volume of wearable material and deeper heat treatment. In addition, medium-track dozer undercarriages move for 80-90 % of SMU (Service Meter Unit) hours and require more undercarriage maintenance and service/refurbishment on components. That’s why Berco is committed to delivering a complete service and competitive products.
