Damage to rubber buffers and preventive maintenance
The rubber buffers should be checked for cracks and deformation in the course of every scheduled maintenance inspection.
Always replace damaged or defective rubber buffers in good time. This can significantly extend the service life of the other buffers, as a defective buffer can cause the unnecessary transfer of loading stresses to its remaining intact counterparts.
The service life of buffers depends to a great extent on where and for what tasks the machine is deployed. Continuous jump operation in the course of extremely demanding earthworks is a typical cause of premature wear on damping components.
Always use the machine under consideration of its operating weight and the scheduled task.
