KOBELCO CK1600 is a lattice boom hydraulic crawler crane, with a lift capacity of 160 Tons. Crane bottom rollers directly support the entire weight of the crane, adapt to complex terrain and ensure the crawler tracks normal operation.
Forging Crane Lower Roller’s Advantages:
- Superior Material Performance
Forging by high temperature and high pressure alters the metal granular structure, eliminates internal defects (such as air pores), enhances the density of the material, and can reach tensile strength of over 1200MPa, improving impact toughness by 30%-50%.
So, forging track roller’s service life is 40%-60% longer than casting’s
- Precision and reliability
Precise moulding can control the tolerance within ± 0.2mm, ensure precise coupling with track shoes, reducing abnormal wear.
Forging process parameters (temperature, pressure, speed) are controllable, parts consistency far exceeds casting, and defect rate can be controlled below 0.5%
