Upgrading the weight capacity of trucks is a legitimate need for many vehicle owners and transportation businesses in Vietnam, aiming to optimize economic efficiency and meet the changing demands of the goods market. However, increasing weight capacity is not a simple and unrestricted process. It requires strict adherence to legal regulations and a specific procedure. This article from Xe Tải Mỹ Đình will provide a comprehensive and detailed overview of the truck weight capacity upgrade procedure, helping readers understand the necessary steps to carry it out legally and effectively.
Understanding Truck Weight Capacity Upgrades
Before delving into the truck weight capacity upgrade procedure, we need to understand the essence of this process. Upgrading truck weight capacity, also known as payload capacity modification, is the process of changing the structure and technical specifications of a vehicle compared to its original approved design, with the aim of increasing its load-bearing capacity. This may involve changing the suspension system, chassis, axles, tires, and many other components.
The main reason why vehicle owners want to upgrade weight capacity is to carry more goods per trip, thereby reducing transportation costs per unit of goods and increasing profits. This need is particularly common in the context of an increasingly competitive and diverse goods transportation market.
However, it is crucial to emphasize that upgrading truck weight capacity must comply with legal regulations. Unauthorized weight capacity upgrades exceeding permitted limits not only endanger traffic safety but also violate the law and can result in severe penalties.
Key Legal Regulations Regarding Truck Weight Capacity Upgrades
To ensure the truck weight capacity upgrade process is legal, vehicle owners need to be well-versed in current legal regulations. Below are some important points excerpted from Circular 85/2014/TT-BGTVT, although there may have been updates, referring to it still provides a basic foundation of knowledge:
- Restrictions on modifications for older vehicles: Vehicles older than 15 years are generally not allowed to be modified to change their purpose of use.
- Limitations on modifying imported truck bodies: There are certain restrictions on modifying imported truck bodies, especially for new vehicles used for less than 6 months.
- Prohibition of vehicle type conversion: It is not allowed to convert cargo vehicles into passenger vehicles or vice versa.
- Restrictions on modifying critical systems: This Circular also regulates against modifying the suspension, brake, and steering systems of vehicles, except for some special cases specifically regulated.
- Limitations on increasing truck body dimensions: Increasing the inner dimensions and volume of the truck body is restricted. If a truck roof has been installed, the height of the body sides cannot be increased.
- Ensuring weight after modification: The total weight of the vehicle after modification must not exceed the designed value and regulations on road and bridge weight limits.
- Regulations on replacement parts: Modifications are only allowed to change one of the two main components: the main frame assembly or the engine.
- Prohibition of using used parts: When modifying, it is not allowed to use old, used systems, except for specialized equipment.
Important Note: Legal regulations on motor vehicle modifications may be amended and updated over time. Therefore, vehicle owners need to proactively seek and update information from official sources of competent state agencies to ensure compliance with current regulations.
Step-by-Step Truck Weight Capacity Upgrade Procedure
To carry out the truck weight capacity upgrade procedure accurately and legally, you need to follow these steps:
Step 1: Prepare the Dossier
This is the first crucial step, determining the success of the weight capacity upgrade process. The dossier to be prepared includes:
- Technical design explanation of the motor vehicle (original copy): This is a document detailing the technical design changes planned to be implemented on the vehicle to increase weight capacity. This explanation must be prepared by a qualified design unit.
- Technical drawings (original copy): Accompanying the technical explanation are technical drawings clearly showing the modification details, changes in dimensions, and vehicle structure. These drawings also need to be prepared by a qualified design unit.
- Dossier requesting design appraisal: This dossier includes a Declaration form for requesting appraisal of modified motor vehicle design (according to the prescribed form) and related technical documents (technical explanation, drawings). This dossier will be submitted to the Vietnam Register or the Department of Transport for appraisal.
Step 2: Design Appraisal
After preparing the complete dossier, you will submit it to one of the following agencies:
- Vietnam Register: For large-scale, complex truck modifications or special cases as regulated.
- Department of Transport: For ordinary trucks, design appraisal can be carried out at the local Department of Transport.
The appraisal agency will review and evaluate your design dossier. If the dossier meets the technical requirements and current regulations, the appraisal agency will issue a Certificate of Appraisal of Modified Motor Vehicle Design. This is an important permit for you to proceed with vehicle modification.
Step 3: Perform Vehicle Modification at a Permitted Unit
After obtaining the Certificate of Appraisal of Design, you need to choose a unit that is qualified and permitted to perform motor vehicle modifications to carry out the weight capacity upgrade of your vehicle. The modification process must be carried out in accordance with the approved design and in compliance with technical and safety procedures.
Step 4: Acceptance Testing and Registration Inspection
After completing the modification, you need to conduct acceptance testing and re-register the vehicle to obtain a Certificate of Inspection of Safety and Environmental Protection for Modified Motor Vehicles. This process includes:
- Vehicle Acceptance Testing: The modification unit and the vehicle owner conduct acceptance testing of the quality and technical aspects of the modified vehicle, ensuring the vehicle meets the requirements according to the approved design.
- Registration Inspection of Modified Vehicle: You bring the vehicle to a Motor Vehicle Registration Center for re-inspection. The dossier for registration inspection of a modified vehicle includes:
- Vehicle registration certificate (original copy)
- Certificate of Appraisal of Modified Motor Vehicle Design (copy)
- Dossier of acceptance testing of modified motor vehicle
- Other documents as required by the Registration Center.
If the vehicle meets the inspection requirements, the Registration Center will issue a Certificate of Inspection of Safety and Environmental Protection for Modified Motor Vehicles and update the vehicle’s new weight capacity information into the registration system.
Important Notes for Smooth Truck Weight Capacity Upgrade Procedures
- Thoroughly understand regulations: Before starting any procedures, thoroughly understand the current legal regulations on motor vehicle modifications, especially those related to truck weight capacity upgrades.
- Choose reputable design and modification units: Choosing capable, experienced, and reputable units will ensure the quality of design and modification, and help the procedural process run more smoothly.
- Prepare a complete and accurate dossier: A complete and accurate dossier is crucial for the appraisal and registration inspection process to be quick.
- Thoroughly check the vehicle after modification: After modification, thoroughly check the technical condition of the vehicle, ensuring it operates safely and stably before putting it into use.
- Comply with weight capacity regulations: After successfully upgrading weight capacity, always comply with the permitted weight capacity regulations when operating the vehicle, avoid overloading which is dangerous and violates the law.
