A Bunker Trailer is a specialized pressurized tanker designed for transporting bulk powdered materials such as cement, fly ash, lime powder, granular products, and industrial dry materials. These trailers are built with a sealed, pressurized tank, which allows for easy and fast pneumatic unloading directly into silos or storage units.

The aerodynamic tank shape minimizes residue, ensures maximum loading efficiency, and reduces the risk of material moisture. With a strong chassis, reinforced steel tank, and advanced pneumatic systems, the Bunker Trailer is an essential vehicle for industries that rely on clean, efficient, and moisture-free bulk material transportation.


Key Features of the Bunker Trailer

Pressurized Tank System

Built with high-pressure discharge technology that enables fast and complete unloading using air compressors.

High-Capacity Design

Tanks typically range from 35,000 to 60,000 liters, providing large-volume transport for cement and powdered materials.

Reinforced Steel Structure

Constructed using ST52 or high-strength alloy steel with anti-corrosion coating for long service life.

Efficient Unloading Mechanism

Equipped with fluidized beds, air chambers, and discharge valves that ensure smooth and clog-free unloading.

Three-Axle Stability

Multiple axles ensure improved load distribution, better road handling, and increased transport safety.

Moisture-Proof Design

Completely sealed tank prevents moisture entry, keeping materials dry and preserving product quality.

Optional Compressor Unit

Can be equipped with on-board compressors for autonomous unloading without external power sources.

Bunker trailers are designed for dry bulk powders, including cement, lime powder, fly ash, flour, plastic granules, and other moisture-sensitive materials.

The trailer uses a pressurized pneumatic system. Compressed air fluidizes the material and pushes it through discharge valves directly into silos, ensuring fast and clean unloading.

Some models need an external compressor at the unloading site; however, many Bunker Trailers come with an optional onboard diesel compressor for full independence during unloading.
