Executive Summary
A leading UK food manufacturer operating a 24/7 processing facility experienced escalating maintenance costs and production delays due to failing trolley castors. Industrial Supplies Co delivered a complete fleet upgrade using food-grade stainless steel castors with enhanced braking systems, reducing trolley-related breakdowns by 62% and generating £34,000 annual maintenance savings.
The Challenge
Operating Environment
- Facility: 15,000m² chilled processing area (0-4°C)
- Operations: 24/7 three-shift pattern
- Fleet: 450 ingredient and product trolleys (200-400kg capacity)
- Floor type: Epoxy-coated concrete, regular washdown
Problems Identified
- Carbon steel castors corroding within 6 months
- Wheel bearings failing due to water ingress during washdown
- Brake mechanisms seizing, creating safety hazards
- Wheel materials degrading from cleaning chemicals
Quantified Impact
| Metric | Baseline (Pre-Upgrade) |
|---|---|
| Trolley breakdowns per month | 47 |
| Average repair time | 45 minutes |
| Production delays (hours/month) | 35 |
| Annual maintenance spend | £78,000 |
The Solution
Specification Development
| Requirement | Specification | Product Selected |
|---|---|---|
| Corrosion resistance | Food-grade, washdown proof | 304 stainless steel housing |
| Load capacity | 400kg per trolley (4 castors) | 150kg rated per castor |
| Chemical resistance | Chlorinated cleaners, caustic | Glass-filled nylon wheels |
| Temperature range | -20°C to +40°C | Low-temp rated bearings |
| Braking | Reliable in wet conditions | Stainless steel brake mechanism |
Implementation
The upgrade was phased across 8 weeks to minimise operational disruption:
- Weeks 1-2: High-use production line trolleys (150 units)
- Weeks 3-4: Ingredient storage trolleys (120 units)
- Weeks 5-6: Despatch area trolleys (100 units)
- Weeks 7-8: Remaining fleet and spares provisioning (80 units + 50 spare castors)
Results
✓ 62% reduction in trolley breakdowns (47/month → 18/month)
✓ 71% reduction in production delays (35 hours/month → 10 hours/month)
✓ £34,000 annual maintenance saving (£78K → £44K)
✓ 71% reduction in production delays (35 hours/month → 10 hours/month)
✓ £34,000 annual maintenance saving (£78K → £44K)
Post-Upgrade Metrics
| Metric | Before | After | Improvement |
|---|---|---|---|
| Breakdowns/month | 47 | 18 | -62% |
| Production delays (hrs/month) | 35 | 10 | -71% |
| Maintenance spend/year | £78,000 | £44,000 | -44% |
| Castor lifespan (projected) | 8 months | 3+ years | +350% |
Return on Investment
- Project cost: £52,000 (including installation)
- Annual saving: £34,000
- Payback period: 18 months
- 5-year saving: £118,000
