What’s the Heaviest Tow Truck?

Tow trucks come in a variety of sizes and shapes, and they can be used for different purposes. But when it comes to the heaviest tow truck, there is one that stands out from the rest.

The Kenworth W900 is the world’s heaviest tow truck, weighing in at a whopping 38 tons. This monster machine was designed to take on the toughest jobs, such as hauling heavy loads of timber or pulling large pieces of construction equipment.

The Kenworth W900 is powered by a 17-liter diesel engine that produces up to 500 horsepower. It also has an impressive 17-speed transmission and two axles with a total of 10 wheels.

This allows it to carry more than double the weight of most other tow trucks. It has a maximum towing capacity of 40 tons and can haul up to 100 tons when equipped with additional axles.

For operators who don’t need quite so much power, there are several other heavy-duty tow trucks available on the market today. Some of these include the Freightliner M2 106, Peterbilt 389, Western Star 4900EX and International ProStar+. Each of these models have their own unique features but can still handle loads up to 30 tons.

No matter which tow truck you choose, they are all designed with safety in mind. Every model is equipped with brakes that are capable of stopping quickly and safely, as well as other features such as airbags and roll bars for added protection in case of an accident.


When it comes to the heaviest tow truck around, nothing beats the Kenworth W900. With its powerful engine and 10-wheel design, this monster machine has a maximum capacity of 40 tons – making it perfect for those big hauling jobs. Other heavy-duty tow trucks may not be able to compete with its power but still offer plenty of capabilities for operators who don’t need quite so much muscle.
