****Here’s the Question everybody asks about the Giraffeg4 System****

I know the question, because it’s the same question I asked my engineers when we first designed the GiraffeG4 System…

Question…With the GiraffeG4 System, can I measure a bridge, trestle or tree from a distance before I get there? Because when I reach the  obstacle it might be too late.




The GiraffeG4 overhead collision alert system has a wide range of uses:

Oversize Loads
Will measure hazards 12 feet from where it is mounted . . . mount it at 9 feet, it is good to 21 feet.

  • My name is David Valiga from Pennsylvania. I have a Freightliner classic. I haul primarily over sized loads. Number 1 rule of hauling oversize , never screw up getting out of a screw up. You make a wrong turn and of course you’re worried about the height. So if I come up to an object I’m not familiar with the GiraffeG4 tells me the exact height. I know whether I can get under it or not. The GiraffeG4 just gives me peace of mind now. I don’t have to guess, I don’t have to stop in the middle of the road wondering if it’s clear. The GiraffeG4 is just a wonderful tool. I probably count on it more than anything I have in this truck. I absolutely love it.

  • Using the GiraffeG4 gives me the extra bit of confidence - along with my high pole to protect the load, if I have contact on the pole and need to back up to remeasure the GiraffeG4 gives me a readout of the height so I can inform the driver of the height. The GiraffeG4 is a great tool for the high pole car operator and for the driver with no pole car. ... PS: I have fourteen years experience and I think GiraffeG4 will give you the edge to do a great job and to protect the load.

  • Yes, the GiraffeG4 has saved us time and money. We bought the GiraffeG4 because we do many loads that are tall. Now when something is questionable, like a fuel island or an unlabeled bridge, we can be sure with the GiraffeG4.

  • I have been in the heavy haul trucking business for over 29 years. ... On the bottom of every permit it states that the "accuracy of the permit is the drivers responsibility." ... Knowing exactly how high a structure truly is has its own peace of mind. The ability to know that you can dump the air and clear a bridge on route versus calling 911 and waiting to explain how the route won't work, the lost time and delay costs justifies this unit at twice the price. ... Saves time and miles, all comes back to your time and money in additional miles. This product is a great tool to have, and should be in every escort vehicle. It should be required equipment, it is in our trucks!

  • The GiraffeG4 unit was with me on my most recent trip in the western states and it saved my air conditioner on my 5th wheel trailer. There were two R.R. crossing that were not marked correctly and low trees in a remote camp grounds...

  • This product is indispensable to anyone with a tall RV.

I’m originally from Georgia, I haven’t made it to Hawaii cause I can’t get there-the other 49 I’ve pretty much covered all of them. I’ve done everything from dump trucking to semi’s over the road, I’ve done a little bit of all of it, I’m 29 years in. If you’re going to NY, Philly or Chicago the GiraffeG4 is a great tool to have. All the bridges are mismarked. I used to haul prefab houses down in Georgia-18ft high. I wish I had the GiraffeG4 back in those days- I wouldn’t feel safe traveling without it anymore. I would recommend it to any driver, all drivers, they should have it.

My husband relies on his Giraffe G4 for protection from low clearance obstructions. The installation and setup were easy and it allows for peace of mind when approaching any questionable area. We travel approximately 8,000 miles per year with our high profile fifth wheel.

... We purchased our Giraffe G4 unit following our most devastating RVing experience. ... While stopping for fuel on an interstate, we cleared the stations overhead going into the fuel island. There was a road grade change on the outbound side which altered the clearance. This resulted in hitting the overhead as we pulled out. We were actually stuck under it. Naturally embarrassed and simultaneously devastated, we let the air out of the tires, the air bags on the truck and the Trail-Air pin. With the remains of our air conditioner cleared from the roof we delivered the rig to our dealership. There was over $7,000 in damage to the roof of our coach.

Our Giraffe G4 won’t let us be taken by surprise in the future. With the Giraffe, we have peace of mind and real time knowledge of what is over our heads so this won’t happen again!

Travel safe.
