Empowering 20‑Ton Tag Trailers with Air‑Actuated Ramps

Upgrading a 20‑ton tag trailer to air‑operated ramps brings both convenience and heavy‑duty functionality. This retrofit transforms manual ramp deployment into smooth, safe, and efficient operation—greatly enhancing loading and unloading tasks for heavy equipment.
Why Air‑Powered Ramps Matter

• Faster deployment — Air cylinders lift and lower the ramps at the push of a button, saving time.
  
• Reduced operator strain — Eliminates the physical effort required to handle heavy steel ramps manually.
  
• Improved safety — Controlled motion prevents sudden drops or swings that could cause injury or damage.
  
• Enhanced versatility — More responsive loading options, useful in tight job sites or frequent unloading scenarios.
  

Core Components of the Conversion
To retrofit your trailer effectively, you’ll need:

• Air actuator cylinders — Sized to support the ramp load and trailer angle.
  
• Compressor or air supply — A compact on-board compressor or truck system to feed the actuators.
  
• Control valve and hose network — A solenoid valve with pilot control linked to dashboard switch or remote.
  
• Mounting brackets and reinforcements — Strong mounting welded or bolted to the chassis and ramp hinge points.
  
• Pressure relief and check valves — Ensuring safe, reliable operation without overextending force.
  

Retrofit Process Overview

• Assess existing suspension and ramp geometry — Understand hinge location, ramp weight, and bed angle.
  
• Select appropriate cylinder size — Ensure stroke length and force ratings align with ramp mass.
  
• Fabricate or install mounting plates — Reinforce side rail or dovetail sections for actuator loads.
  
• Install air supply and plumbing — Route hoses neatly, secure, and pressure test.
  
• Wire and mount control switch or remote — Keep it accessible from both rear and tow vehicle.
  
• Test and adjust travel limits — Fine‑tune ramp positions for optimal clearance and operation.
  

Real-World Insight
A contractor performing daily loading of heavy skid steers installed air‑actuated ramps on his 20‑ton tag trailer. One morning on a muddy field, manual ramp deployment failed due to rack binding and debris. With his retrofit, he simply hit the switch, and the ramps smoothly extended despite mud buildup—saving the day and preventing operational delays.
Another example comes from a rental yard upgrade: with air‑actuated ramps, customers were able to load equipment independently in under a minute. The yard's manual handling injuries dropped sharply, underscoring both safety and efficiency gains.
Helpful Terms to Know

• Tag Trailer — A trailer towed behind another trailer, often with tandem axle setups for high capacity.
  
• Actuator Cylinder — A hydraulic or pneumatic piston assembly used to move heavy components like ramps.
  
• Solenoid Valve — An electrically controlled valve that directs air to extend or retract the actuators.
  
• Check Valve — A one‑way valve preventing air loss when the system is deactivated.
  
• Mounting Bracket — A steel fitting that fastens the actuator securely, distributing loads into the trailer frame.
  

Final Thoughts
An air‑ramp retrofit is more than a convenience—it’s an upgrade to productivity, safety, and operational flexibility. Whether hauling equipment into remote locations or streamlining depot workflows, air‑actuated ramps empower operators to load confidently and efficiently.
