This is a very practical and important concern. Large workshops usually have complex road and transport conditions, and every customer's facility is different. Common challenges include grooves left by dismantled tracks, height differences at entrances, and even gravel or steel-paved areas - all of which can affect the performance of a trackless transfer cart.
In fact, choosing the right wheel type can completely resolve these issues. Just as different tires suit different road conditions, different wheels suit different workshop floors. Let's look at several common floor conditions:
1. Flat Surfaces: Epoxy Flooring, Hardened Concrete Floors
If your workshop has a flat epoxy floor or a polished concrete surface, that's ideal. These floors are clean, smooth, and minimize wheel wear. On such surfaces, almost any wheel material can be used.
In this case, we generally recommend polyurethane wheels. They are hard and highly wear-resistant, run smoothly and quietly, and won't scratch the floor. Most importantly, they are cost-effective, making them ideal for workshops with strict requirements for floor cleanliness. Their high load-bearing capacity also ensures durability and stability on flat surfaces.
However, because polyurethane wheels are relatively hard, they are not suitable for environments with debris or uneven bumps.
2. Rough, Gravelly, or Slightly Uneven Floors
Some older workshops have rough, gravelly, or slightly uneven floors, sometimes with debris such as stones or metal shavings. Steel plates may even be laid to cover potholes. On such surfaces, polyurethane wheels wear quickly and may suffer tread damage, drastically shortening their service life.
For these conditions, rubber wheels are a better choice. Rubber has excellent elasticity and shock absorption, which reduces the impact of uneven ground, protects the cart's structure, and increases stability. On slightly potholed floors, rubber wheels provide better grip and help prevent slipping.
This makes them particularly suitable for workshops in industries such as hardware, foundry, or building materials, where floor surfaces are often complex. Their elasticity also makes them well-suited for environments with small gravel.
3. Floors with Track Grooves, Steel Plate Joints, or Large Height Differences
This is one of the biggest challenges in many workshops - especially older facilities with rail grooves, steel plates at entrances, or 2–5 cm height differences between indoor and outdoor areas.
If the wheels are too small or too hard, they can easily get stuck in grooves, or excessive vibration from thresholds can destabilize the load. For these conditions, we recommend large-diameter, treaded tires:
Large diameter helps the cart roll over bumps, grooves, or doorway gaps more easily.
Tread design improves grip and reduces the risk of slipping.
Larger contact surface distributes the load more evenly, protecting wheels from deformation and damage.
These wheels function much like off-road tires, designed for complex road conditions. Many customers have reported that after switching to large-tread wheels, their carts navigate grooves and thresholds smoothly without wheels getting stuck or peeling.
Summary: The Right Wheels Solve Many Problems
Choosing the wrong wheels can cause a lot of unnecessary trouble. The right wheels, however, ensure smooth operation and long service life.
Polyurethane wheels → Best for clean, flat floors
Rubber wheels → Best for rough, uneven, or gravelly floors
Large-tread tires → Best for grooves, thresholds, and large height differences
If you're unsure which type is right for your workshop, we can conduct an on-site survey to help you customize the most suitable wheel configuration. Remember: it's better to adapt the equipment to your environment than to force your operations to adapt to the equipment.
