Metal Folding Cart With Wheels is a portable tool that uses an iron frame, PP impact-resistant basket and EVA buffer layer, combined with a modular folding structure to achieve a balance between high strength and lightness.

1. High-strength composite material

• Iron frame: Q235 cold-rolled steel plate, yield strength ≥235MPa, passed 10,000 full-load vibration tests without deformation, hinge fatigue life ＞50,000 times.

• PP basket: temperature resistance range -30℃ to 90℃, impact energy ＞40, in line with FDA food contact safety certification, can directly transport fresh ingredients.

• EVA buffer layer: shock absorption coefficient ＞60%, effectively reducing the breakage rate of fragile products during transportation by 90%.

2. All-terrain wheel system

• Front wheel configuration: double set of 360° PU universal wheels, bearing accuracy ABEC-5, minimum turning radius 40cm, suitable shelf channel width ≥60cm.

• Rear wheel performance: solid rubber wheel, rolling resistance coefficient 0.06, passed ASTM F2641 standard gravel road test.

• Braking system: electromagnetic parking brake, automatically triggered when slope inclination ≤15°, passed EN 12150-1 safety certification.

3. Intelligent folding and space optimization

• Folding mechanism: four-link hinge design, folding operation force ≤8N, unfolding/folding time<5 seconds="">

• Packing density: 5 units/box, sea transportation volume is reduced by 45% compared with the non-folding solution, and the container loading rate is increased to 90%.

4. Human-computer interaction optimization

• Handle parameters: TPE coated handle, grip contact area increased by 30%, in line with ISO 11228-3 push-pull specification, hand pressure<10kpa 2="" for="" hours="" of="" continuous="" use.="">

• Basket partition: removable partition + anti-slip silicone pad, no displacement of goods when the tilt angle is ≤10°.

5. Environmental tolerance and compliance certification

• Corrosion resistance: zinc coating thickness ≥ 80μm, salt spray test > 1200 hours, suitable for coastal high humidity environment.

• Environmental protection standards: iron frame recycling rate > 95%, PP material passed GRS certification, carbon footprint < 7kg CO₂/unit.

1. Commercial and supermarket high-frequency replenishment

• Dynamic load-bearing: push resistance ≤ 12N under 25kg full load, employees' daily replenishment mileage reduced by 30%.

• Intelligent compatibility: barcode scanning slot integrated on the side of the basket, inventory counting efficiency increased by 40%.

2. Family vertical transportation

• Stair climbing: supports stair transportation from 1st to 6th floor, single trip transportation of bottled water/rice, flour, grain and oil and other heavy objects, and the risk of lumbar muscle strain is reduced by 70%.

• Space optimization: folded thickness of 25cm, can be hung on the wall or placed behind the door, reducing the space occupied by the family by 80%.

3. Efficient market operation

• Quick loading and unloading: Quick-release hooks are installed on the side of the basket, and 100kg of fruits and vegetables can be transported in a single trip, reducing the frequency of replenishment by stall owners by 50%.

• Sanitary management: The drainage rate of the mesh bottom is >95%, the residual blood and water in seafood transportation is<0.1l>
