Executive Summary

Written by Mark Thompson, Technical Sales Manager at Industrial Supplies Co with 15+ years experience in logistics and warehouse equipment specification.

A major third-party logistics provider operating a 50,000 sq ft distribution centre in the West Midlands needed to replace worn castors across their entire picking trolley fleet. The ageing castors were causing increased noise levels, floor marking, and frequent breakdowns that disrupted operations.

Key Results: 480 heavy-duty blue elastic castors supplied and fitted over one weekend, 40% reduction in castor-related maintenance calls, zero floor marking issues, significant noise reduction in picking aisles.

Project Background

The distribution centre handles next-day deliveries for multiple e-commerce retailers, operating 18 hours per day, 6 days per week. Their fleet of 120 picking trolleys is in constant use, with each trolley travelling an estimated 15-20 kilometres daily across the warehouse floor.

The original castors—standard black rubber units fitted when the trolleys were purchased 4 years ago—had reached end of life. Symptoms included flat spots, stiff swivel action, visible rubber degradation, and black marking on the recently painted floor.

Client Requirements

• Load capacity: 180kg per castor minimum (trolleys carry up to 500kg when fully loaded)
• Non-marking: Essential for newly painted warehouse floor
• Quiet operation: Reduce noise in picking aisles for staff welfare
• Durability: 3+ year lifespan under continuous heavy use
• Weekend installation: Zero disruption to weekday operations
• Budget: Competitive bulk pricing for 480 units

Our Solution

After reviewing the trolley specifications and operating conditions, we recommended our 100mm Heavy-Duty Blue Elastic Rubber Castors. The combination of swivel and braked units provides manoeuvrability with safety when stationary.

Frequently Asked Questions

What castors are best for warehouse trolleys?

For warehouse trolleys, heavy-duty swivel castors with 150-200kg load capacity per wheel are recommended. Blue elastic rubber wheels offer quiet operation and floor protection. Always use braked castors for safety when loading/unloading.

How often should industrial castors be replaced?

Quality industrial castors last 3-5 years in heavy warehouse use. Signs that replacement is needed include flat spots on wheels, reduced swivel action, visible rubber degradation, and floor marking. Preventive replacement programs reduce unexpected equipment downtime.

What load capacity do I need for warehouse castors?

Calculate the total load (trolley weight plus maximum cargo) and divide by the number of wheels. Add a 25% safety margin. For example, a 500kg maximum load on 4 wheels requires castors rated at 150kg+ each. Always specify based on dynamic (moving) load, not static.

Are blue rubber castors better than black?

Blue elastic rubber castors are non-marking, quieter, and offer better floor protection than standard black rubber. They're ideal for clean warehouse environments, showrooms, and healthcare facilities where floor marking is unacceptable.

Do you supply castors in bulk for trade customers?
