Heavy Duty Shopping Trolley is an industrial-grade shopping trolley designed for high-intensity handling scenarios.

1. Military-grade materials and structures:

• Frame: 2.0mm cold-rolled steel pipe, hot-dip galvanized, rust-proof grade reaches ASTM A123 Class 3, resistant to acid and alkali corrosion.

• Basket: diamond-shaped perforated steel plate, compressive strength ≥250N/cm², can carry irregular heavy objects without deformation.

• Wheel set: PU solid tire + double-row ball bearing, load capacity 30KG/wheel, adaptable temperature -30℃ to 80℃.

• Handle: non-slip rubber coating, in line with ISO 23936-2 oil-contaminated environment grip standard.

2. Engineering mechanics design

• Load-bearing system: static load-bearing 25KG, dynamic impact resistance 15KG@1.5m drop test without damage.

• X-shaped bottom frame reinforcement + four-corner diagonal bracing structure, lateral torsional strength increased by 60%, to avoid overload rollover.

• Precise size adaptation: frame size W45×D43×H87cm, matching the side-by-side stacking spacing of European standard pallets, optimizing storage space utilization. The basket volume is 48L, which can accommodate 4 standard logistics boxes or 12 bags of 25kg building materials and auxiliary materials.

3. Industrial-grade logistics adaptation

• 5 units/box, carton compressive strength ≥800kgf, suitable for cross-border sea freight stacking.

• Single box gross weight 15.4kg, perfectly adapted to FedEx/UPS land transportation specifications.

• Pre-installation rate 95%, end users only need 3 steps of buckle installation, support tool-free barehand operation.

4. Special scene optimization

• Safety design: Red emergency stop warning strips are attached to the four corners of the frame to improve visibility in low-light environments.

• Rear wheel mechanical lock, slope parking angle ≤15°.

• Scalability: Top/side hook module, external tool rack, fire extinguisher bracket, etc., adapt to site inspection needs.

1. Construction and decoration industry

Applied to construction sites, it helps to reduce the injury rate of building materials handling and replace manual shoulder carrying. PU puncture-proof tires can withstand steel bar debris ground and reduce the cost of tire blowout repair and downtime.

2. Cold chain logistics industry

Applied to frozen warehouse cargo transfer, it helps to maintain low-temperature operation efficiency, avoid slipping and tipping, and reduce temperature fluctuations caused by basket tipping.

3. Manufacturing and factory warehousing

Applied to production line material scheduling, it helps to achieve JIT lean production.
