Preventative Maintenance Schedule for a conveyor/tunnel
By Robert Andre
Observation is the most important aspect of these checks. Remember to: observe, look, note, and confirm. It’s important to catch small problems early before they cause greater damage.
Opening Checks: These are performed prior to opening the carwash and before running any water.
- Check the hydraulic fluid: All leaks should be repaired immediately.
- Look for low oil levels, leaks, and sub-standard performance of the overall system.
- Do a wet test: This portion of the opening check is performed before opening and is designed to bring all of the equipment on line and ready to wash vehicles. The wet down procedure is programmed into the controller and allows you to concentrate on observing the equipment.
- Visually check all of the chemical barrel levels in the equipment room (you do not want to run out of a chemical for any reason. The entire wash process can be compromised if this happens.) Please note: When changing a barrel, always clean and test the foot valve. Transfer the last of the old container into the new container when possible. Besides just looking for barrels that need to be replaced, you are looking for excessive use and minimal use.
- Check the salt level of the water softener system. Fill with salt as needed. It’s better to have too much than too little.
Operational Checks: Performed while the wash is operating, these checks confirm the equipment is functioning properly and correctly adjusted.
- Walk through the tunnel while a wash is occurring with all extra service applicators operational. Check for overall performance and specific adjustment indicators.
- Inspect the equipment room while a wash is occurring with all extra service applicators operational. Check for overall performance and specific adjustment indicators.
Closing Checks: These are performed after the wash has closed for the day. These checks confirm the equipment is functioning properly and is correctly adjusted. In addition, any heavily soiled cloth is cleaned.
- Inspect the tunnel. Look for any damage that may have occurred during the day.
- Inspect the equipment room. Check for any damage or problems that have come up during the day.
The two most important aspects of the weekly checks are lubrication and close inspection.
- Pay close attention to lubrication. When weekly procedures are performed, long-term wear and tear will become apparent and further deterioration can be avoided. The Weekly Procedures are divided up between the tunnel and the equipment room for a typical conveyor carwash.
The two most important aspects of the monthly checks are cleaning and close inspection. The assignments are divided up between the tunnel and the equipment room; and are scheduled for individual days assigned at the manager’s discretion.
- Thoroughly clean the equipment.
- Closely inspect long-term wear points to gauge overall wear and tear on the equipment.
Annual and Semi-Annual Tasks
The scheduling of individual tasks is determined by the manager of the facility. However, they must be done within 30 days, plus or minus, of their due dates.
- Look to replace wearable items, such as chains and rollers.
