What’s type of Liebherr track rollers can you supply?
We can produce the lower roller and top roller for the Liebherr crawler crane. The lower roller is connected with the track shoes at the lower part of the undercarriage to share the weight of the crawler and prevent the tracks from slipping laterally during driving, to ensure stable driving of the machine. The top roller is in the upper part of the undercarriage to support the tracks, make sure the tracks run smoothly, and reduce body shaking.

How can you control the quality?
Best Material-ROUND Steel
Liebherr equips its crawler crane roller bodies with high-strength alloy steels, specifically 40Mn2 or 42CrMo. These materials are selected for their exceptional hardness, superior wear resistance, and high toughness. This combination significantly reduces abrasion and deformation under extreme loads and harsh operating conditions.
Standard Process
Replacing duplex metal (iron-copper composite) bushings with 100% fine copper bushings offers distinct advantages in specific applications. Pure copper provides superior thermal conductivity, corrosion resistance, and uniform wear properties. The specified thickness range (6mm–10mm) ensures adequate structural integrity while maximizing space efficiency in assemblies.
Production Process
The most important process of Liebherr crawler crane track rollers is hardening and tempering, if the rollers are not undergo hardening and tempering, its mechanical properties, yield strength and tensile strength will not be very good, the roller will be slip easily during work.
