Why is Polyurethane (PU) the standard for warehouses?

PU offers an optimal balance of load capacity, wear resistance, and low rolling resistance. For clean, flat warehouses, it outlasts rubber significantly.

When should I choose rubber over PU?

Choose rubber when traction is the primary bottleneck, such as on steep ramps, wet floors, or dusty concrete, where PU would slip and trigger safety sensors.

Do I need a suspended drive wheel?

If your warehouse has expansion joints, door sills, or uneven concrete, a rigid drive wheel will momentarily lose contact. Suspension ensures constant normal force and traction.

What makes a wheel "Heavy-Duty"?

Heavy-duty wheels use premium polymers like Vulkollan with higher rebound resilience to reduce overheating risk. They also feature reinforced iron or steel hubs and high-capacity bearings.

What is Traction Margin?

It is the ratio of Available Traction (Normal Force x friction coefficient) to Required Traction (Rolling + Ramp + Acceleration forces). We recommend a margin above 1.5x.

Is an AGV drive wheel for warehousing factory use different from a generic AGV wheel?

Yes. Warehousing factory routes combine long travel, pallet loads, ramps, dock dust, floor joints, and repeated acceleration. A generic wheel can pass static load checks but still fail traction, heat, or preload checks.

What should I measure before asking for a quote?

Measure loaded mass, empty vehicle mass, wheel layout, drive-wheel preload, maximum ramp, floor finish, expansion-joint height, contamination, speed, duty cycle, and braking case.

What should I do if the calculator shows low traction margin?

Treat it as a stop-and-review signal. Reduce payload or ramp speed, increase drive-wheel normal force, test a higher-grip tread, or request a suspended drive module before approving fleet purchase.

When is premium PU such as Vulkollan worth the cost?

Consider it for high duty cycle, heavy load, repeated turns, 24/7 logistics, or heat-related tread failures. It still needs hub, bearing, temperature, and route validation.

Why do expansion joints change the wheel decision?

A rigid chassis can unload the drive wheel over joints and gaps. Once normal force drops, available traction drops even if the tread material has good grip on a flat test surface.

Should a warehousing AGV use two or four drive wheels?

Two drive wheels are simpler and common for pallet movers, but four drive wheels can improve drive-wheel load share and redundancy. The tradeoff is higher control, suspension, and cost complexity.

Can this tool approve final wheel size?

No. It is a procurement screening tool. Final approval needs supplier drawings, load distribution, motor torque, brake case, floor test data, and pilot run observations.

Key Conclusions for Warehouse AGVs

PU is the Default

For clean, level warehouses, standard Polyurethane handles high loads with minimal wear.

Ramps Require Traction

Ramps > 5% drastically reduce traction margin, often necessitating rubber wheels.

Suspension Matters

Uneven joints cause drive wheels to lose floor contact. Preload suspension ensures continuous traction.

Method Used by the Tool

1. Convert route inputs

Payload, vehicle mass, wheel count, ramp grade, speed, and floor condition are converted into gross mass and screening force inputs.

2. Estimate traction margin

The tool compares rolling, ramp, and acceleration demand against available drive-wheel normal force multiplied by a floor-friction placeholder.

3. Choose the review path

The result maps the margin and floor risk to PU, rubber, Vulkollan, or suspended drive-wheel review rather than treating the number as final approval.

This is a screening model for RFQ and pilot planning. It does not replace supplier drawings, motor torque curves, brake tests, or measured floor-friction data.

Material Comparison

Material	Best For	Watch Out	Decision Evidence
Standard PU	Clean epoxy or polished concrete, flat routes, low debris	Can lose margin on dust, oil, wet patches, steep ramps, or open floor joints.	Best used as the default only after route friction and wheel load are measured on the actual warehouse floor.
High-Traction Rubber	Dusty or wet floors, ramps above 5%, shock absorption needs	Higher rolling resistance, faster wear, and possible flat-spotting under heavy static load.	Use when the calculator shows low traction margin or when pilot tests show PU slip under braking.
Vulkollan (Premium PU)	Heavy loads, 24/7 throughput, repeated turns and acceleration	Higher upfront cost; overkill for standard low-speed pallet movers.	Use for dynamic-load and heat-risk screening, then request supplier duty-cycle and temperature data.

Application Scenarios

Standard Pallet Mover

1200kg payload, standard concrete, 2% ramp, 1.5m/s

Standard PU Drive Wheel. Traction margin is sufficient; PU provides best wear life.

Cold Storage / Dusty Warehouse

1000kg payload, slippery floor, 0% ramp

High-Traction Rubber. The reduced friction on dusty/wet floors makes PU a slip risk.

Heavy Payload Tow Tractor

5000kg payload, smooth epoxy, 5% ramp, 2m/s

Heavy-Duty PU (Vulkollan). The combination of high speed and extreme dynamic load requires premium polymers to avoid overheating.

Risk & Mitigations

Assuming 100% load distribution

Impact: Rigid drive wheels lose contact on uneven floors or expansion joints, causing the AGV to stall or spin out.

Fix: Specify pre-loaded suspension drive wheel modules on any floor with >3mm deviance per meter.

Ignoring floor contamination (VDI 2510 risk)

Impact: Calculated PU traction fails in reality; braking distance increases dangerously if oil or dust is present.

Fix: Adopt a lower friction coefficient (mu=0.3) in calculations or switch to High-Traction Rubber.

Undersizing for ramps

Impact: Wheel slip going up; inability to hold position or brake safely going down with heavy payloads.

Fix: Calculate required traction using F = m * g * sin(theta) and mandate a >1.5x safety margin.
