Pneumatic Truck Loading and Unloading

Faster Rates – Less Downtime – Superior Dust Control

Pneumatic conveying is an elegant, efficient solution that allows us to engineer systems without excessive use of horsepower.

Our unique design concept provides for limited maintenance and prevents premature wear on components. Savings in the use of horsepower translates into less system heat and product degradation.

There are many advantages to pneumatic truck trailer unloading compared to mechanical conveying. Less moving parts means less breakdowns, and an enclosed system means easy dust control. Another important advantage is flexibility in routing – we can convey material to places others can’t.

Our Pneumatic Conveying Solution Eliminates:

  • Blow-by Air
  • Worn Shaft Seals
  • Bent Rotors
  • Holes in Elbows
  • Wasted Horsepower and Energy
  • Worn Out Housings
  • Chain Drive Maintenance
  • Valves with Inherent Leaks

High Rates

These high-rate systems employ either diesel or electric driven portable units that can range from 10 to 200 horsepower and can move material at a rate of one to one-hundred ton per hour.

We Achieve High Rates with All Types of Truck Trailers:

  • Hopper
  • Dump
  • Pressure Differential Pneumatic Trailers

We Provide Choices:

Depending on the application, proven solutions could include header systems for multiple tracks and car spots, choices of vacuum, pressure, or combination systems and portable and self-powered units.

Other Options Include:

  • Booster for Multiple Trailers
  • Choices of Vacuum, Pressure, or Combination Systems
  • Portable and Self-Powered Units


Our systems feature industrial-duty NEMA-rated control panels that automate much of the process, allowing your system to run smoothly, with less downtime.

We build control panels to meet your application needs and may include:

  • NEMA-Rated Panels
  • Disconnect Switch
  • Primary Circuit Protection
  • Industrial-Duty Buttons, Selector Switches, and Door Devices
  • PLC – Programmable Logic Controller
  • Motor Starters
  • HMI – Human Machine Interface
  • LED Indicator Lights
  • Variable-Speed Controls
  • Touchscreen
  • Remote Networking Capability
  • Data Collection

Accessories that enable the operators to work safely and efficiently include easy to connect aluminum vacuum gate adapters with leak proof connections, manifolds, and flex hoses of stainless steel and food-grade rubber to mate railcars to systems.

System Support:

To adjust our scope of supply to meet your needs, US Systems can also supply peripheral components:

  • Storage Silos
  • Dust Collectors
  • Convey Piping
  • Couplers
  • Elbows
  • Industrial Automation Controls
  • Manifolds
