Cargoes the parameters of which do not meet the normal dimensions or weight permitted for carriage are considered oversized. These may be pipes, building structures, concrete slabs, engineering goods, agricultural and specialized machinery, other cargo of complex configuration or weight. Deviation from the approved parameters of at least one indicator is the basis for recognition of the cargo to be oversized.

The standard is considered to be:

  • height up to 4 m;
  • length up to 20 m;
  • width of 2.55 m;
  • weight up to 38 tons.
  • Transportation of the oversized cargo is carried by special vehicles with a mandatory agreement in the road patrol service of the route.

    Requirements for special vehicles Standard freight transport provides transportation of cargo with width of 2.5 m and length of 13.6 m, and height of 3 m, weighing not more than 20 tons.

    In most cases, it is not suitable for moving the oversized freight, they are transported on special low-bed multi-axle platforms or trawls. Low-bed platforms don’t have restrictive boards. Trawls belong to a variety of truck trailers up to 4 m in width and up to 16 m in length. They can take loads of up to 150 tons.

    Transport is selected taking into account the limit of axle load and the permissible carrying capacity. For transportation of pipes we use the pipe truck, and concrete slabs are best carried by slab trailers.

    Proper positioning and fixing Great importance in transportation of oversized cargo is paid to its positioning and fixing on the platform.

    In most cases, the center of gravity in irregular shaped cargo is offset from the center. Experienced riggers carried out the competent weight distribution to determine the center of gravity of complex parts or cargo. This is a major operation that allows you to position the cargo on the platform at the right place, in the most stable position with even distribution of the total mass of the cargo on the bearing axles.

    The cargo is securely fastened to the platform. If the center of gravity location was specified incorrectly, or the load was not properly fixed, the emergence of serious troubles is possible.

    They include:

  • Turning (rollover) of the transport by the cargo weight while oversteering.
  • Falling of the cargo which is not properly fixed from the platform at the time of maneuvering.
  • Improperly secured oversized cargo can jump out of the anchorage during heavy braking and crush the truck cabin with the driver.
  • Transportation of cargo is not allowed, if the load on the bearing axles exceeds the permissible parameters of the platform manufacturer.

    Duties of the driver The driver of a vehicle transporting the oversized cargo is obliged to constantly monitor the general condition of the cargo, the strength level of fasteners, the fixation degree in fastening or limiters. Difficult to transport oversized loads are accompanied by traffic police car with the officers, who, if necessary, may temporarily suspend the movement of other vehicles on a particular portion of the roadway.

    Envisaged regulative rules for movement of the oversized loads require the compliance with several conditions.

    The oversized cargo located on the platform shall not:

  • Overlap the driver's view.
  • Close the lights, reflectors, marking lights, license plates and other signals.
  • Reduce resistance to the road surface of the vehicle.
  • Embarrass the driving.
  • Deteriorate the environment (to throw out harmful gases, dirt, debris, create a lot of noise).
  • In the dark or foggy weather the binding condition for safe transportation is a symbol on the lorry (truck) bumper of white reflector lamp or light, and lighting of the rear side or the trailer with red reflector or light.

    If the load overhangs in front or behind the platform by more than 1 m and 40 cm from the sides, it is marked with a sign - "Oversized cargo" (in a square the alternating red and white diagonal stripes of equal width).

    Special rules Transportation of oversized cargoes is regulated by special rules.

    They apply to the vehicles, parameters of which without load or with load placed on them, exceed:

  • 4 m in height, marking from the surface of the roadway;
  • longer than 20 m with a trailer;
  • wider than 2.55 m (for refrigerators of insulated bodies 2.6 m is permissible).

    The same rules apply to the vehicles transporting the load, which overhangs for 2 meters beyond the rear point of marker lights.

    Safety transportation Safety transportation by INTERFREIGHT is provided by extensive experience of logistics, freight forwarders and drivers. Qualification of all employees has been approved by certificates, permits to the transport of oversized and dangerous cargoes, skills of usage the special equipment and reliable fastening of goods on platforms, repeated trainings on the technique of safe movement of goods.

    The speed of vehicles with oversized cargo shall not exceed: 60 km/h on the highway; 15 km/h on the bridge.

    Both sides of the driver's cab is secured by two additional mirrors for larger viewing area.

    Compliance with the route For each cargo the logistics of INTERFREIGHT develop the best route, taking into account the strength of the roadway, and the height and width of possible obstacles (tunnels, power lines, bridges). Moving along a certain route is agreed by special permits, so the driver does not have the right to deviate from the pre-agreed route.

    It prohibited the movement:

  • in the areas with icy track;
  • in poor visibility;
  • on the sidelines.
  • Truck parking is allowed only on the special parking lots. Secure of the parking is provided by four wheel chocks, which are installed immediately after complete stop of a road-train in the parking lot.

    Traffic of the vehicle with load shall be stopped immediately in the event of:

  • breakage;
  • threats to security;
  • damage of load fixtures or limiting holders.
  • Requirements for the technical equipment of road-trains The brake system of the tractor unit shall be operated by the brake pedal, and the semi-trailer brake shall be equipped with a parking brake.

    In case of damage or rupture of lines connecting the tractor and trailer, automatic stop of the platform with cargo shall be guaranteed.

    Identification marks The vehicles carrying the oversized cargoes are marked by special signs, such as:

  • yellow or orange flashing beacons;
  • “Road train”;
  • “Oversized cargo”;
  • “Long vehicle”.
  • Adherence to the rules of transportation of the oversized cargo will allow professional drivers to deliver the cargo without damage and accidents just in time.
