What is a straight truck?

What is a straight truck?

To transport large quantities of goods, you must choose the right heavy-duty vehicle. A rigid truck is the best choice for many logistics needs.

But what exactly is a rigid truck, and what are its specific features? Here’s a detailed overview of this essential vehicle for freight transport.

The straight truck

A rigid truck is a heavy-duty vehicle designed or modified to carry a container or heavy load directly on its chassis. Unlike a tractor-trailer, which pulls a trailer, the rigid truck carries the load directly.

It generally weighs over 3.5 tons and is known for its ability to handle various body types adapted to different goods.

This vehicle is especially useful for direct home delivery, as it can reach residential zones with limited access.

 

Main components of a rigid truck

A rigid truck consists of several elements:

  • Cab: The cab size varies by model; some include a sleeper compartment for long trips, enhancing driver comfort.
  • Chassis: The base structure supporting the container or body. It can hold various forms — tankers, dumpers, refrigerated vans, etc.
  • Engine: A powerful engine is necessary for carrying heavy loads.

  • Axles: These support the vehicle’s weight. A single axle can bear up to 13 tons; a rigid truck can have up to four for maximum capacity.

Dimensions of a straight truck

The size of a rigid truck depends on its maximum load capacity. The most common models are the 19-ton truck and the 12-ton truck.

 

19-ton rigid truck

This type of truck can be up to 12 meters long, 2.55 meters wide, and 4 meters high. It can carry up to 50 m³.

Dimensions may vary depending on the body type used (e.g., tankers or tippers).

 

12-ton rigid truck

Smaller than the 19-ton version, the 12-ton truck measures around 10 m long, 2.55 m wide, and 3.60 m high. Interior dimensions also vary: 7.5 m length, 2.45 m width, 2.40–2.50 m height.

It’s ideal for mid-range deliveries and is frequently used for direct home delivery.

The use of a straight truck

Rigid trucks are versatile and can carry a wide variety of goods. This flexibility comes from the many body types that can be mounted to the chassis, each suited for specific needs.

 

Food products

Rigid trucks with refrigerated bodies are essential for transporting raw materials, meat, and perishables.

They maintain a controlled temperature to preserve freshness while meeting strict health standards.

 

Chemical and liquid products

Transporting chemical reagents and liquids requires special tanks made from corrosion-resistant materials.

These trucks are fitted with safety systems to prevent leaks and ensure secure transport of hazardous materials.

 

Construction materials

Rigid trucks carry heavy and bulky materials like wooden pallets, stones, and tools.
Often equipped with dumpers or flatbeds, they’re essential for job site deliveries.

 

Moving

Moving trucks have large, secure compartments to transport furniture and personal belongings.

With tail lifts and special suspension, they make loading/unloading easier while minimizing damage.

 

Sand and waste

Rigid trucks with dump bodies transport bulk materials like sand or industrial waste.
These robust dumpers are used in construction and waste management for effective site deliveries.

 

Other additional uses

  • Vehicle transport: Equipped with ramps to carry cars and utility vehicles.

  • Emergency services: Converted into fire or recovery vehicles for rapid intervention.

  • Animal transport: With ventilated and secure compartments for animal welfare on long journeys.

 

Additional equipment

Rigid trucks often include tools to improve handling:

  • Crane: Installed at the front or rear, helps load and unload cargo.

  • Tail lift: Acts as a lifting platform for heavy goods — saves time and avoids docking, ideal for heavy loads.
