The noise generated by stainless steel manual carts primarily stems from their wheel-ground friction, structural vibrations, and usage conditions. Here's a detailed breakdown:

1. Wheel-Related Factors

Material and Design:

Hard plastic or metal wheels on rough surfaces produce loud noises. Softer materials like rubber or polyurethane (with shock-absorbing properties) reduce noise.

Example: Gear-like wheels (with teeth) create loud "gear effect" noise, while slanted grooves or smooth surfaces minimize this.

Bearing Quality:

Poor-quality bearings increase friction and vibration, leading to squeaking or grinding sounds.

2. Frame and Structure

Looseness or Defects:

Wobbly frames, loose bolts, or welding defects cause rattling or metallic clashes during movement.

Resonance:

Thin stainless steel panels may vibrate and amplify noise, especially on uneven terrain.

3. Ground Conditions

Surface Type:

Noise spikes on bumpy, uneven floors (e.g., gravel vs. smooth concrete).

Debris:

Small stones or dirt trapped in wheels produce clicking or scraping sounds.

4. Maintenance Issues

Lack of Lubrication:

Dry wheel bearings or axles increase friction and wear, causing squeaks.

Wheel Wear:

Worn-out treads or misaligned wheels create imbalance and noise.
