By Beth Mueller, PFlow Industries

Even the most dependable equipment benefits from regular inspections by a qualified technician. These inspections can help prevent unexpected downtime and keep your operation running smoothly.

Crush Downtime with Preventive Maintenance

Preventative maintenance is your secret weapon against downtime. It’s like that ounce of prevention that saves you a pound of trouble (and a hefty repair bill). Here’s why a well-defined preventive maintenance program is a game-changer:

• Dodge the Downtime Demon: Say goodbye to unexpected breakdowns that halt production;
• Slash Repair Costs: Catch small issues early to avoid expensive repairs later;
• Extend Your VRC’s Lifespan: Regular care keeps your equipment running smoothly for years to come;
• Safety First: Reduce the risk of accidents caused by malfunctioning equipment; and
• Peak Performance, Maximum Efficiency: Regularly maintained machinery operates at its best, leading to optimized productivity.

Let’s break down the key steps involved in a thorough, scheduled inspection.

8 Critical Steps to Keep Your VRC Running Smoothly

While inspection protocols can vary depending on your specific VRC model and any custom features, here are some key steps that apply to any VRC. Please note that preventive maintenance should be conducted only by a qualified and trained service technician.

1. Consult a Playbook

Don’t wing it!  Following a detailed preventive maintenance checklist or playbook for all VRCs ensures you’re doing the right maintenance at the right time.

2. Put Safety First

Before you get started, prioritize safety by following safety protocols located in owner’s manuals and preventive maintenance checklists.

3. Scrutinize Safety Components

The most important place to begin is with inspecting all safety components/devices. Interlocks, gates, safety cams, chains, brake gap/wear (mechanical VRCs), down solenoid and hydraulic hose connections (hydraulic VRCs), and DeckLocks (if applicable) to ensure they are working properly.

4. Check All Operational Components

After inspecting the VRC’s safety components, direct your attention to reviewing operational components such as wheel blocks and chain tensioners to ensure they are within proper tolerance and adjust if needed.

5. Electrical Check-Up

Inspect all electrical components, checking for signs of wear/damage, or loose connections and frayed wires.

6. Ensure Level Stops

Verify that the VRC stops flush with the floor or ramp at each level. Misalignment can lead to loading and unloading issues and may also indicate that the unit has been overloaded or operated incorrectly.

7. Make it Clear

Inspect and clean areas under and around the VRC to remove debris or obstructions that could hinder operation.

8. Document and Report

Keeping accurate records is crucial. It ensures that issues are addressed promptly and helps you track maintenance history and identify potential problems early. Remember to document and correct any unsafe conditions immediately.
