Multi-functional Folding Shopping Cart

I. Structural Design 

  1. Materials & Frame 

• The hand truck utilizes a metal frame that balances lightweight construction with high strength, ensuring load-bearing stability. 

• A four-wheel system is equipped at the base: two large main wheels for bearing heavy loads and two smaller swivel wheels for enhanced maneuverability. 

  2. Functional Layout 

•Layered Storage: The upper section features a high-capacity mesh basket, while the lower open platform allows organized storage of bulky items and small tools. 

•Folding Mechanism: Designed with hinges and buckles for rapid folding, reducing volume by approximately 70% when collapsed, ideal for storage or vehicle transport. 

  3. Detail Optimization 

• Side support bars adopt a triangular mechanical structure to prevent cargo tilting; the handle is wrapped in anti-slip material for comfortable and effortless grip. 

II. Performance 

  1. Load Capacity & Durability 

• Static load capacity: 150 kg; dynamic load capacity: 80 kg. The reinforced metal frame and thickened wheel axles meet high-frequency搬运 demands. 

• Wheels made of high-elasticity rubber material, offering wear resistance and slip resistance, adaptable to tile, concrete, gravel, and other surfaces. 

  2. Handling Experience 

• Swivel wheels enable 360° rotation with a minimum turning radius of 40 cm, ensuring agile movement in narrow spaces like stairwells or warehouse aisles. 

• The ergonomically designed handle height eliminates bending during pushing, reducing fatigue during prolonged use. 

  3. Folding Efficiency 

• Folding/unfolding takes only 10 seconds without tools; folded thickness is ~15 cm, allowing vertical wall storage or flat placement in a car trunk.
