What Are The Different Types Of Track Rollers?
Integral crane track rollers are characterized by their simple structure, with components such as the roller body and bearings usually designed as a non-detachable whole. This means that the entire crawler crane parts of lower roller needs to be replaced as a whole during maintenance or replacement. The advantage of this design is that the structure is more robust, the error in the assembly process is reduced, the sealing performance is improved, and the possibility of failure is reduced. However, this also means that if a part is damaged, the entire assembly may need to be replaced, which may increase the cost of repair.
Split crane bottom rollers have a more flexible design, and their components (such as wheel body, bearings, bushings, etc.) can be removed and replaced separately. This design allows for targeted replacement of worn or damaged parts during maintenance, thereby reducing maintenance costs. The disadvantage of split crane bottom rollers is that more delicate operations are required during assembly to ensure proper alignment and sealing between the components, otherwise leakage or premature wear may occur.
