Mobile Cold Storage Unit Trailer Dual Axle

Mobile Cold Storage Unit Trailer Dual Axle. A Heavy-Duty Dual Axle (Tandem) Mobile Cold Storage Unit Trailer is designed for the high-capacity transport of perishable goods, butchery meats, event catering, and cold-chain logistics. The dual axle setup distributes massive structural weight evenly, preventing sway on highways and enabling a loading capacity of up to 2 tons.

This complete engineering specification sheet outlines a dual-temperature capable (Chiller / Deep Freeze) mobile cold room.

📋 Technical Structural Specifications

1. Dimensions & Capacities

• Internal Length: 2400 mm to 3000 mm (Standard dual axle sizes)

• Internal Width: 1500 mm to 1700 mm

• Internal Height: 1800 mm to 1900 mm

• Payload Capacity / GVM: 2000 kg to 2500 kg (2–2.5 Ton rating)

• Tare Weight: Approx. 750 kg–900 kg (unloaded weight)

2. Chassis, Suspension & Running Gear

• Frame & Chassis: Heavy-duty, hot-dipped galvanized channel steel matrix chassis with anti-rust primers.

• Axles: Tandem/Dual Axles (1500kg load capacity per axle) equipped with mechanical override or electric braking systems and integrated safety handbrake.

• Suspension: Commercial-grade multi-leaf spring suspension system tailored for heavy, shifting thermal weight.

• Wheels & Tyres: 4x 14″ Commercial-rated, road-tough tyres + 1x matching spare wheel mounted to the exterior chassis.

• Stabilization: 2x to 4x Heavy-duty drop-down crank stabilizer legs to lock the trailer in position and avoid tipping when stepped into.

• Jockey Wheel: 60mm heavy-duty adjustable telescopic jockey wheel with a reinforced clamp.

3. Thermal Cold Room Body Construction

• Wall & Roof Insulation: 75mm to 100mm high-density Interlocking Polyurethane (PU) or Polystyrene sandwich panels. These provide maximum cold retention and minimize heat transfer through solar radiation.

• Cold Room Door: Heavy-duty, fully insulated swing door with commercial automotive-grade rubber gaskets and seals.

• Locking Mechanism: Heavy-duty stainless steel Container-style Cam-Lock and latch bar system with padlocking facility and an internal safety escape release handle (prevents staff entrapment).

• Flooring: Multi-layered floor configuration:

  • Marine plywood base board.

  • High-density insulation layer.

  • Finished with a hot-dipped galvanized steel sheet or anti-slip aluminum checker plate overlay for easy washdowns and impact resistance from crates.

❄️ Refrigeration Unit & Controls

• Cooling Capacity: 12,000 BTU to 18,000 BTU commercial dual-temperature refrigeration unit (depending on box length).

• Temperature Range Capabilities:

  • Chiller Mode: $0^\circ\text{C}$ to $+5^\circ\text{C}$ (For fresh produce, dairy, beverages, and flowers).

  • Deep Freeze Mode: $-15^\circ\text{C}$ to $-20^\circ\text{C}$ (For ice, frozen meats, seafood, and ice cream).

• Compressor Protective Cage: Externally mounted compressor protected inside a heavy-duty, lockable steel cage on the drawbar to guard against stones and theft.

• Blower Coil: Internal single or dual-fan evaporator blower coil designed for rapid temperature pull-down.

• Control Panel: Microprocessor-controlled digital thermostat display mounted externally with programmable auto-defrost parameters.

⚡ Electrical & Power Distribution

• Power Inlet: 220V–240V Single Phase external waterproof industrial inlet socket.

• Circuit Protection: Built-in distribution board with dedicated Overload Protection, Earth Leakage, and digital voltage monitoring (crucial when running off portable site generators).

• Interior Lighting: 1x Moisture-proof, low-temperature LED bunker light with a manual switch.

• Power Draw Efficiency: Designed for low amperage start-ups to safely run off a minimum 5.5 kVA or larger portable generator when stationary or in transit.

🚨 Safety, Compliance & Accessories

• Internal Shelving: Optional multi-tiered, removable food-grade stainless steel or galvanized slatted shelving structures down both long walls.

• Drainage: Integrated floor drainage plugs with external relief valves to flush out wastewater during cleaning.

• Road Compliance: Full LED rear tail lights, amber side reflectors, reflective chevron taping, and licensed registration documentation readiness.

• • Safety Gear: Internal safety door release, mudguards on both wheel arches, and heavy-duty wheel chocks
