A brush fire truck is basically a specialized firefighting vehicle. It is designed to combat wildfires and brush in areas where the traditional fire engines can’t reach. These trucks are built on 4×4 commercial truck chassis and can easily be used for off-road purposes. They also have water tanks and pump-and-roll functionality that the firefighters use to spray water while the truck is moving.
In today’s article, we’ll talk about different components of these trucks and how different types are used for various purposes. Let’s get started.
Key Components of Brush Fire Truck
Chassis and drivetrain are the foundation of any truck. Most brush fire trucks are built on 4×4 chassis offered by famous manufacturers, such as Dodge and Ford. Similarly, to increase payload capacity, medium-duty chassis can also be used.
Then comes the water tank, which usually holds 50 to 750 gallons (depending on the type of vehicle). This tank is usually made from stainless steel or fiberglass. The tanks also have internal baffles that prevent water from surging (when the truck is in motion).
These trucks also have unique pump systems. For fast-moving grass fires, the pump-and-roll capability is used, with water sprayed as the truck moves.
Types of Brush Fire Truck
These trucks are classified by fire engines, starting from Type 3 to Type 7.
Type 3 is the largest truck and can carry a minimum of a 500-gallon water tank. The pump can also spray 150 gallons per minute. This truck requires a minimum of 3 people to handle.
The Type 4 falls in the medium range. They can throw only 50 gallons per minute and are used for initial attack operations.
In Type 5, the truck is a bit smaller and offers better maneuverability than the other types mentioned above. These trucks can carry a minimum of a 400-gallon water tank. Type 6 is the most common truck used by municipal departments.
When Fire Departments Actually Use Brush Trucks
These trucks are primarily used to tackle wildland fires. For grass and brush fires, these vehicles provide initial attack, allowing the flames to be easily contained. If the wildfire is larger, these trucks can even perform mop-up duties after the main fire is extinguished.
These trucks are also used to provide structural protection during construction and development work. They create a kind of defensible space around buildings so the approaching fire doesn’t catch them.
How Are the Brush Trucks Actually Chosen?
When choosing a brush truck, it’s important to closely analyze the fire situation and the ground conditions. For example, flat, hilly, and mountainous terrain all require different kinds of solutions. Similarly, you also need to check how far the water is from the fire source and the road condition.
Operationally, type 6 units are common in municipal departments because they offer good maneuverability and sufficient water capacity. Similarly, type 7 units are well-suited to rapid-response roles.
Bottom Lines
These brush trucks offer something that a traditional truck can’t. A properly equipped truck can make a difference between controlling a fire and watching it grow into a major incident.
