All-Plastic Shopping Cart — Large Capacity Model with Silent Swivel Wheels

Custom made

Core Advantages

    All-plastic construction – Basket, frame, and push handle are injection-molded HDPE or PP. No exposed metal welding points. Suitable for high-humidity environments (fresh food sections, seafood areas) and sheltered outdoor locations.

    Corrosion resistance – The plastic body does not corrode in contact with salt spray, mild acids (fruit and vegetable juices), or mild alkalis (cleaners). Metal components are limited to sealed caster bearings and connection bolts (stainless steel or galvanized). Suitable for locations where contact with corrosive substances may occur.

    Silent swivel casters – All four casters are swivel type with double-sealed ball bearings. Wheel surface material is TPR or polyurethane. On tile or epoxy floors, measured rolling noise ranges from 45 to 55 dB when empty at 3 km/h. Four-wheel swivel design allows 360-degree in-place rotation.

    Lightweight – Empty cart weight ranges from 6 to 12 kg (excluding packaging), 40% to 60% lighter than metal shopping carts of equivalent volume. Reduces operator physical exertion during pushing, nesting, and transport.

    Nesting storage – Nesting slots are built into the basket base and rear wall, with nesting interfaces reinforced with stainless steel or galvanized steel inserts. Ten nested empty carts occupy a total length of 1.2 to 1.5 times the length of a single cart.

Product Features

    Body material – HDPE or PP injection-molded, wall thickness from 3.0 to 5.0 mm. Basket and frame available as one-piece molded or bolt-assembled configuration.

    Basket volume – 80 to 150 liters, depending on custom dimensions.

    Color options – Red, blue, green, yellow, black, gray, white, or custom colors. Material is solid color throughout (not painted). Surface scratches do not reveal a different substrate.

    Caster specifications – Four swivel casters, diameter from 120 to 150 mm. Wheel core: double sealed ball bearings (IP54 dust/water resistance rating). Wheel surface: TPR or polyurethane. Brake available on single or dual casters (optional).

    Push handle – Injection-molded plastic handle, integrated with or bolted to the body. Anti-slip texture on grip surface. Handle height: 900 to 1000 mm above the floor.

    Nesting method – Vertical or angled nesting, nesting angle 10 to 15 degrees. Nesting interface insert material: 304 stainless steel or galvanized steel.

    Load capacity – Basket rated load: 40 to 70 kg. Total cart load not exceeding 70 kg.

    Child seat (optional) – HDPE or PP injection-molded seat, located between the push handle and basket. Seat load capacity: 15 to 20 kg. Includes PP safety belt. Seat surface includes anti-slip texture and leg protection openings.

    Accessory options – Cup holders, phone holders, advertisement slots, and plastic shopping bag hooks.

    Ambient temperature range – -20 to 50°C.

Application Scenarios

    Supermarket fresh food and seafood sections (high humidity, potential saltwater contact).

    Sheltered outdoor shopping venues (open-air markets, seasonal fairs).

    Car wash customer waiting areas (for temporary storage of items removed from vehicles).

    Swimming pool or water park changing areas (moisture-resistant, mold-resistant).

    Medical facilities or rehabilitation centers (smooth, easy-clean surfaces, no metal rust risk).

Frequently Asked Questions and Precautions

Frequently Asked Questions

Q: Is an all-plastic shopping cart more prone to breakage than a metal one?
A: Injection-molded HDPE or PP materials have impact resistance under normal use conditions (within rated load, non-extreme temperatures). The material toughness withstands minor bumps in daily use. However, plastic has lower rigidity than metal. Concentrated heavy impacts (e.g., forklift collision) may cause cracking, whereas a metal frame would dent but not crack.

Q: Does the plastic frame become brittle after long-term use?
A: HDPE and PP materials do not experience significant embrittlement for 5 to 8 years in indoor or non-direct-UV environments. For sheltered outdoor use, material life is approximately 3 to 5 years. UV stabilizers added to the material extend service life. Direct sunlight exposure exceeding 12 months causes surface fading and reduced toughness.

Q: Will caster bearings rust after contact with water?
A: Casters are equipped with sealed bearings (IP54 dust/water resistance), pre-lubricated with grease. Short-term water contact (cleaning, wet floors) does not cause rusting. Prolonged immersion or direct high-pressure water jet at bearing seals may cause water ingress. When cleaning, tilt the cart to avoid directing water jets at bearing seals.

Precautions

    Do not exceed 70 kg in the basket. The plastic basket base includes reinforcing ribs, but overloading causes permanent sagging deformation.

    Avoid placing hot items exceeding 60°C directly into the plastic basket, which may cause localized softening and deformation.

    When nesting, ensure the front basket rim is fully engaged in the nesting slot of the following basket. Only release after an audible click is heard. Plastic nesting interfaces wear faster than metal ones; inspect the insert wear every 12 months.

    Clean with neutral detergent and a soft cloth. Avoid steel wool, abrasives, or solvents containing acetone or benzene, which damage the plastic surface gloss layer or cause chemical cracking.

    When not in use for extended outdoor periods, store carts indoors or under shade to reduce UV exposure.

    Inspect caster bearing rotation smoothness monthly. If sticking or unusual noise occurs, check for debris ingress at bearing seals; replace casters if necessary.

    This shopping cart is not intended for slopes exceeding 5 degrees, as fully loaded four-swivel-caster configurations may experience lateral drift.
