Liebherr LTR1220 Top Roller Production Core Steps

1 Premium Raw Material Selection

The quality of raw materials directly decides how long crane top rollers last. Cheap raw materials often cause top rollers cracking and fast wear. We manufacture Link-Belt LTR1220 top rollers from 40Mn2 alloy steel, and every steel batch comes with complete traceability records. This material choice greatly boosts top roller’s load capacity, wear resistance and ability to resist impact

2 Precision CNC Machining

After rough machining and heat treatment processes, we will use CNC machines to further polish the top rollers. Every surface detail gets precise trimming to eliminate burrs and uneven spots. This can not only make the appearance of top rollers neat and uniform, but also increase the smoothness of the surface and reduce the resistance during installation and operation of top rollers. Less friction also slows down part abrasion and extends the service life of the whole undercarriage.

3 Heat Treatment Process

The heat treatment process is essential for producing high-quality top rollers for crawler cranes. Unlike other ordinary manufacturers of crawler crane undercarriage parts who neglect heat treatment processes, every undercarriage parts produced in our factory requires a dual heat treatment process of quenching and tempering. In order to improve the wear resistance and impact resistance of the undercarriage parts of the crawler crane, and extend its service life.
