Double-Tier, High-Capacity Supermarket Shopping Cart

Custom made

Core Advantages

    Volume efficiency per floor area: The double-tier design increases vertical space utilisation, offering approximately 40–60% more storage capacity compared to conventional single-tier models (exact increase depends on custom dimensions).

    Product separation: Physical division between two levels enables simultaneous storage of ambient goods, chilled packaged items, and non-food products, minimising repeated searching during shopping.

    Structural durability: The frame uses welded metal joints with reinforced connections, supporting a maximum load up to the customised limit (e.g., ≤50kg per cart).

    Aisle adaptability: Cart width and turning radius can be parametrically customised to match main aisles and end-cap clearances, reducing traffic congestion.

Product Features

    Double-tier structure: Upper level as a separate basket or flat platform; lower level as a deep basket or open flatbed, connected by rigid support posts.

    Caster configuration: Four-wheel steering system (front swivel casters + rear fixed direction casters, or all swivel casters optional). Wheel material: TPR or PU, diameter range: 100mm–125mm.

    Handle design: Push-handle height adjustable from 850mm to 1050mm, with anti-slip surface or full-coverage plastic sheath.

    Accessory interfaces: Side-mounted cup holders, signage card slots, or electronic shelf label brackets (optional).

    Nesting & storage: Rear stacking plugs allow carts to nest into each other when not in use, saving storage space.

Application Scenarios

    Hypermarkets: Bulk purchasing needs for rice, oil, beverages, and cleaning supplies.

    Warehouse clubs: Accommodates larger basket volumes and multi-pack product purchases.

    Community fresh supermarkets: Upper level for soft products like vegetables and fruits; lower level for boxed items such as eggs and milk.

    Wholesale retail stores: Partitioned display and self-collection of tools, small hardware, or household chemicals.

Common Issues & Solutions

    Issue: Difficulty turning narrow aisles with double-tier carts.
    Solution: Customise cart width (typically 500mm–650mm) and front caster swivel angle (≤90°) based on actual aisle width (common range: 900mm–1100mm). Conduct passage tests with a prototype.

    Issue: Stability concerns when heavy items are placed on the lower level.
    Solution: Specify that the lower basket/plate’s centre of gravity must not exceed the mid-beam height, and maintain a wheelbase of at least 600mm. Request static tip-over test reports from the supplier.

    Issue: Wear on casters or connectors after prolonged use.
    Solution: Use removable caster assemblies (bolt-fixed) and standard-interface connectors. Perform regular inspections (e.g., every 3–6 months) on swivel flexibility and weld integrity.

    Issue: Can carts from different batches nest together?
    Solution: Define stacking interface dimensions and positioning tolerances during customisation. Stacking compatibility may vary across suppliers or batches – recommend one-time purchase of uniform specifications.

Product Precautions

    Load limits: Do not exceed the customised static load per level. Overloading may cause frame deformation or premature wheel wear.

    Cleaning method: Avoid spraying acidic or alkaline cleaners directly onto welds and swivel bearings. Use neutral detergents and soft cloths.

    Temperature environment: For TPR wheels, avoid prolonged exposure to temperatures above 60°C or contact with grease/oil-based solvents.

    Regular inspection points: Every 200 operating hours or quarterly, check handle-to-frame bolts for loosening, and listen for abnormal noises from casters.
