Optimizing Conveyor Maintenance: A Comprehensive Guide to 'Walk the Belt' Inspections
In its typical usage, 'walking the belt' refers to the routine inspection and servicing of conveyors within an operational facility. The individual tasked with this responsibility, often referred to as the 'belt boss' or plant's belt person, systematically walks the conveyor system. During this process, they inspect its operation, make minor adjustments or perform cleaning activities, and make note of any significant issues requiring further attention.
The belt inspector should diligently document observed problems as they arise. For instance, they might note issues like 'The center roller on idler number 127 on Conveyor B is not turning' or 'There is significant spillage at the tail of Conveyor 3.' It is crucial to record these observations immediately rather than waiting until the inspection of a specific conveyor is complete or returning to the maintenance room. Notes can be recorded on paper or a digital device. A basic cell phone can even be used to leave voicemail messages for oneself, ensuring that critical observations are not forgotten amidst daily tasks. Additionally, using a digital camera or smartphone allows the inspector to capture photos of issues, which can then be shared for evaluation.
Remaining stationary while 'walking' the conveyor may seem contradictory, but it is essential for the inspector to carefully observe the belt's operation as it completes at least one full revolution. This allows for a thorough examination of the belt's condition, including its edges, splices, top cover beneath the skirtboard, and tracking, to identify any potential problems. The inspector can also check whether the belt remains centered when loaded and unloaded.
There may arise situations where immediate action is necessary. If the inspector identifies a risk to the belt, conveyor, or plant personnel—such as a tramp iron lodged in the structure, an overheating idler, smoldering material buildup, or other fire hazards—they must stop the belt promptly. Ensuring safety and preserving equipment integrity takes precedence over avoiding unscheduled downtime.
It is crucial that the individual conducting the survey follows a comprehensive checklist of components to inspect during every 'walking the belt' conveyor inspection. This checklist should include manufacturer-recommended maintenance guidelines for various components and subsystems like samplers, scales, metal detectors, and magnets, tailored to each plant's specific needs.
