What indicates that a stacker may not be functioning properly?

Unusual vibrations or noises are key indicators that a stacker may not be functioning properly. When a stacker exhibits these signs, it often suggests underlying mechanical issues that need attention. For example, abnormal vibrations could stem from misaligned components, worn-out parts, or issues with the hydraulic system. Likewise, unusual noises—such as grinding, clanging, or whining—could indicate friction between components or a failure in the drive system. These indicators are critical for ensuring safety and efficiency during operation, as they often precede more significant malfunctions if not addressed promptly. Regular maintenance and attention to these signs can help prevent downtimes and enhance the lifespan of the equipment.
