Metal Folding Shopping Cart is a heavy-duty foldable vehicle with an iron main frame, a PP impact-resistant basket and an EVA buffer layer. It is an innovative tool designed for efficient transportation and convenient storage in multiple scenarios of logistics transportation.

1. Aviation-grade materials and structural strength

Frame material: Q235 cold-rolled steel plate, surface galvanized, passed 10,000 full-load vibration tests without deformation, bending strength > 500N·m.

Basket performance: PP material temperature range -30℃ to 90℃, impact energy > 45J, in line with FDA food contact safety certification, can directly transport fresh ingredients.

2. All-terrain mobile system

Wheel configuration:

Front wheel: 360° universal PU wheel, bearing accuracy ABEC-5, minimum turning radius 40cm, suitable for shelf channel width ≥ 60cm.

Rear wheel: heavy-duty rubber solid wheel, rolling resistance coefficient 0.05, passed ASTM F2641 standard 10km gravel road durability test.

Braking system: electromagnetic parking brake, automatically triggered when the slope inclination is ≤15°, to prevent the risk of slipping, and passed the EN 12150-1 safety certification.

3. Intelligent folding and space optimization

Folding mechanism: four-link hinge structure, folding operation force ≤10N, unfolding/folding time<5 seconds="">

Packing efficiency: 3 units/box, the sea transportation volume is reduced by 50% compared with the non-folding solution, and the container loading rate is increased to 92%.

4. Ergonomic design

Handle parameters: TPE-coated handle, the grip contact area is increased by 35%, in line with ISO 11228-3 push-pull specifications, and the hand pressure is<10kpa 2="" for="" hours="" of="" continuous="" use.="">

Basket partition: removable partition + non-slip silicone pad, no displacement of goods when the inclination angle is ≤12°.

5. Environmental tolerance and compliance certification

Corrosion resistance: salt spray test >1200 hours, suitable for coastal high humidity environment.

Environmental standards: PP material recyclability > 95%, iron frame complies with RoHS directive, heavy metal dissolution < 0.1ppm.

1. Supermarket industry

Applied to high-frequency replenishment in supermarkets:

• Optimization of narrow passage: 5.5-inch 360° universal wheel set is suitable for channels with shelf spacing ≥70cm, with a push rod height of 1.8 meters, and 40kg of goods can be transported at a time, and the replenishment efficiency is 50% higher than that of traditional carts.

• Smart device compatibility: RFID scanning slot is reserved on the top of the basket to support batch sensing and entry of goods, and the queue time at the checkout counter is shortened by 30%.

• Loss control: PP anti-slip basket bottom reduces the risk of tipping of bottled goods, and the cargo damage rate is reduced from 2.3% to 0.5%.

2. Outdoor industry

Applied to mountain activity material transportation:

• All-terrain passability: rubber tire tread depth 4mm, climbing angle ≤8°, can achieve stable transportation of 40kg load on a 30° slope, and the passing speed on gravel roads reaches 3km/h.

• Modular expansion: folding table and cup holder are added on the side to meet the rapid deployment needs of outdoor catering, first aid and other scenarios.

• Extreme environment adaptation: The wheel set elasticity retention rate is greater than 85% in a low temperature environment of -20°C, and the wheel set can work continuously for 8 hours in a desert environment without performance degradation.
