Safety Information
Adhering to these safety guidelines is crucial for preventing injury and damage to the carrier or your vehicle.
- Maximum Load Capacity: Do not exceed the maximum load capacity of 500 lbs (226.8 kg). Overloading can lead to structural failure and accidents.
- Speed Limitation: A recommended maximum speed of 60 mph (96.5 km/h) is suggested. Always adjust your speed according to the weight of your cargo, road conditions, and local speed limits.
- Hitch Compatibility: Ensure the carrier is securely attached to a Class III or IV 2-inch hitch receiver. Verify your vehicle's hitch capacity meets or exceeds the carrier's requirements.
- Secure Cargo: Always use appropriate tie-down straps or ropes to firmly secure all cargo to the designated tie-down points. Prevent any movement of cargo during transit.
- Pre-Trip Inspection: Before each use, inspect all bolts, nuts, and connections for tightness. Ensure the ramp locking mechanism is fully engaged when the ramp is stowed.
- Vehicle Dimensions: Be aware that the cargo carrier increases your vehicle's overall length and potentially width. Exercise caution when backing up, turning, and parking.
- Visibility: Ensure the carrier's reflectors are clean, visible, and not obstructed by cargo.
- Weight Distribution: Distribute cargo weight evenly across the carrier platform to maintain vehicle stability.

Assembly Instructions
Assembly of the Goplus Hitch Cargo Carrier is required. It involves numerous bolts and nuts. For efficient assembly, a power screwdriver and a good socket wrench are highly recommended. Please study the provided diagrams carefully during assembly.
- Unpack and Identify Parts: Carefully unpack all components and lay them out. Refer to the parts list (if included with your product) to identify each piece.
- Attach Hitch Receiver Bar: Connect the hitch receiver bar to the main cargo basket frame. Align the holes and insert the appropriate bolts, washers, and nuts. Tighten these fasteners securely.
- Secure Side Rails: If the side rails are not integrated, attach them to the cargo basket frame using the provided hardware. Ensure they are firmly in place to prevent cargo from falling off.
- Install Loading Ramp: Attach the loading ramp to the cargo basket frame using the hinge pins and any other specified hardware. Ensure the ramp can pivot smoothly and that the locking mechanism (latch pins) functions correctly to secure the ramp in both the deployed and stowed positions.
- Attach Reflectors: Install the red reflectors to the designated areas on the carrier, typically on the rear and sides, to enhance visibility.
- Final Tightening: Double-check all bolts, nuts, and pins to ensure they are fully tightened. Some nuts may have Loctite applied, requiring additional force to engage properly. Do not overtighten aluminum components to avoid damage.
