You don’t know if your load is considered oversized?

Wondering if heavy hauling is available in your industry?

You don’t know how to choose an oversize load transport company?

To help you make the best choices and get your cargo to its destination safely and on time, here are our top expert tips!

What is Oversize Load Transport?

Oversize load transport is regulated by the authority in each jurisdiction through which the vehicles pass. Specifics vary according to weight, length, height and many other details.

In general, an oversized load requires a higher level of planning than a traditional load because of the number of variables that come into play. For example, each jurisdiction has its own public safety and road condition considerations, as well as times of the year when there are size and weight restrictions.

How to know if your load is considered oversized?

There may be a thin line between standard heavy transport and oversize transport. In order to plan properly, it is important to know which measures will be applied or not in every situation.

Oversize Load Transport Regulations in Canada

Restrictions on heavy trucks in Canada are managed and enforced by the specific province through which they travel. It is therefore necessary to plan the optimal route according to the oversized loads carried and the permits on hand.

Generally in Canada, any road transport over 75′ 5” (23 m) long, 8′ 6″ (2.59 m) wide and 13′ 7″ (4.15 m) high is considered oversized. There is no gross weight rule imposed in Canada that indicates a specific limit on the vehicle before considering oversized.

Once loads begin to exceed a certain size threshold, a province or one of its municipalities may impose the need to travel with an escort vehicle.

For precise regulations by province, contact one of our oversize load transport experts.

U.S. Oversize Load Transport Regulations

As in Canada, the size and weight restrictions for a heavy haul depend on the corresponding state legislation and the specific section of highway on which the oversized load travels in the United States.

In general, loads that are greater than 75′ 5” (23 m) long, 8′ 6″ (2.59 m) wide and 13′ 6″ (4.11 m) high is considered oversized trailers in the U.S., however a 53’ (16.15 m) trailer is accepted as legal and the gross weight limit, it is generally 80,000 lbs.

Oversized transport solutions tailored to various industries

Many types of equipment and loads are eligible for oversize load transport. The terms “oversize load” and “oversized load” have nothing to do with the type of load and everything to do with its dimensions. Equipment that typically falls into the oversize category includes:

Building Equipment: cranes, dump trucks, excavators and bulldozers
Building Materials: steel beams and piping
Agricultural Equipment: harvester threshers and tractors
Manufacturing Equipment: assembly lines, conveyors and crushers
Housing: mobile and prefabricated homes

To give you an idea of the main industries served by oversized transport (and its applications), here are the sectors in which we regularly operate at Groupe Bellemare.

What to consider when choosing the best oversize load transport company?

Rates are important, but experience and safety are the main criteria to choose which transport company will be responsible for your oversize load. We recommend that you consider the following factors:

Awards in safety, performance, environmental awareness and customer service quality?

These types of distinctions make it much easier to trust a company. You will know that your shipment is in good hands and have peace of mind!

Are the customer reviews positive?

Some companies are good at speaking well of themselves. However, customer reviews don’t lie and allow you to see real testimonials of experiences with the company. Are they on time? Do the shipments arrive at their destination in good condition? Does the company use optimal routes? You can also contact customers directly with your questions.

Does the company have the right trailer for your needs? How to choose the right equipment?

It is important to be aware of the equipment choices available. Does the company have a sufficient fleet to meet your unique needs? Here is an example of the type of technical equipment offered by Transport Bellemare:

To find out each trailer characteristics and which one is best suited to your situation, contact one of our experts!

Proven Company Expertise and Knowledge

These aspects can be assessed when you visit the company’s website and when you first contact them. Do they adequately answer your questions? Does the company demonstrate its expertise by raising important issues related to regulations and permits? Ask several questions to ensure that the company is meeting your expectations.

Does pricing respect your transport budget?

Of course, pricing is also part of the equation. This can be an important factor if you are deciding between two similar transport companies that both meet your needs!

Examples of Our Achievements

Here are a few major projects that have been successfully completed by our team, as well as the type of equipment used and the cargo transported.

Gaz Métro Tanks

Cargo: Three 135 feet-long (41.15 m) liquefied natural gas (LNG) tanks from New Prague, MN to Sept-Iles. The tanks measure 132’5” (40.36 m) × 12’78” (3.84 m) × 12’9” (3.91 m) and weigh 155 602 lb. This long journey was punctuated by traffic circles: 4 in total!

Equipment Type: “Directional Dolly”

Highlights:

- This contract started in March and ended in October. Numerous negotiations had to be made with the MTQ, as no convoy this long had taken place on route 138 further than Baie-Comeau in the recent past.

- Once on the trailer, we get a total load of 185 ft long, 12 ft wide and 15 ft high.

Wind Turbine

Cargo: Wind Turbine (including blades and towers)

Equipment Type: Expandable trailer for windmill blades (for the blades) and dual trailer (“schnable” with steerable “dolly”) (for the towers).

Highlights: Project carried out over several months in collaboration with our Hauling Sector. Bellemare Heavy Haul & Rigging took care of moving the parts from Marmen’s Matane facility to the port using multi-lines. They were moved by boat from the port of Matane to La Baie (Grande-Anse), and then transported by Transport Bellemare from Grande-Anse to Saint-Gédéon for the Belle-Rivière wind farm.

REM Trains

Cargo: Trains for the new Greater Montreal REM (Réseau express métropolitain)

Equipment Type: Train Directional Trailer (integrated tracks)

Highlights: We have delivered approximately 33% of the trains to date. Since tracks are integrated to the trailer, trains are loaded onto the trailer and unloaded directly onto REM tracks.

A 13-Axle Trip

Cargo: A huge piece used in the paper-making process for the WestRock mill in La Tuque

Equipment Type: 13-axle trailer

Highlights: The Trois-Rivières to La Tuque trip took two days and required the intervention of public utility (Bell, Videotron, Hydro-Québec, etc.) to shift wires during convoy movement.

5 Traits of Successful Project Logistics Shipments - C.H. Robinson

5 Traits of Successful Project Logistics Shipments

  • Copier dans le presse-papiers Copier dans le presse-papiers Lien copié

In the world of project logistics, no two shipments are the same. Each shipment is unique and has its own set of challenges. However, there are some common elements that need to be considered before moving a wind turbine, a transformer, or a module. Because pictures speak volumes, below the five general traits, are pictures of shipments that C.H. Robinson Project Logistics coordinated.

When Project Logistics plans a shipment, it uses 5 general traits.

  1. Shipment Specification (weight and dimensions): This may seem obvious but it’s a key component in deciding what type of trailer will be required for inland trucking-transportation. Some pieces would be able to fit, for example, on a 16- or 19-axle lowboy combination. But if the length of the piece does not allow for it to be placed on the trailer’s well space, then other specialized equipment will have to considered—for instance, a bolster and steerable dolly.
  2. Center of Gravity: This is a crucial component for heavy/over-dimensional freight. For example, some cargo will be designed and fabricated where the majority of the weight is toward one side of the piece and therefore, in order to compensate this imbalance, it needs to be placed on that side of the trailer accordingly (see picture 3).
  3. Origin and Destination: Depending on how large and heavy the cargo is, the potential route(s) for transportation may be limited due to bridges (height and/or weight capacity of the bridge) road restrictions, construction, permitting, street-furniture, etc. There are times, again due to the size of the units and permit approval, where the only way to transport would be to use river barges instead of using trucks or railcars.
  4. Securing/Lifting/Lashing Points: This is vital when one considers the actual handling of the cargo. Regardless of the mode of transportation, project cargo has to be securely and legally fastened to a platform of sorts and, depending on the intricacy of the move, there may be several times where a piece of cargo would have to be lashed, unlashed, and lashed again.
  5. Onsite Supervision: Project cargo can be very complex and one can have the best plan ‘on paper’. However, theory does not always translate efficiently into practice. An experienced project manager supervising onsite can make all the difference in ensuring everything is achieved as planned or, if something goes array, it is coordinated properly.
