Boeing Dual-Driver Truck/Trailer Combination
This video shows one of the unique dual-driver truck/trailer combination
vehicles used by Boeing to transport aircraft wing spars to the Boeing
assembly facility in Everett, Washington. The first driver, as with any
other truck, is in the "front" cab. You can see the second driver in his
cab underneath the trailer, just in front of the rear wheels.
The Hitch Hog Used to Double Tow
Using The Hitch Hog to support all of the tongue weight of a 2nd trailer.
This allows towing a 2nd trailer with no effects on the 1st trailer
The Orininal Gooseneck Easy Coupler
No more crawling into the back or over the side of your pickup to latch
your gooseneck trailer. Lever actuated cam coupler that hitches your
gooseneck trailer fast easy and secure.
Combilift Container Lifter
Video of the Combilift containerlifter. The Combilift containerlifter is
able to transport all sizes of ISO shipping containers. The Containerlifter
hooks on behind a normal Truck and can lift fully loaded containers from
the ground onto the trailer, from trailer to trailer and from trailer to
Pulling the trailer out
Couldn't hitch it back to the truck so we had to jerk her outta there. The
truck that was pulling it is the white dually in the background. Watch the
other video to see that white GMC get pulled out too!
How to Move a 45' Shipping Container up a Mountain with a 22' Truck
No one would haul this container up to my mountain property. It has 30%
grades, no guard rails and the turns are very sharp. A 40' trailer would
never have make it around the corners. My freightliner weighs 17500 lbs
empty. The container weighs 10000 lbs. I figured that the weight of the
engine and fuel would be enough to hold it down. It didn't stay down all
the time since sometimes the front wheels would lift up, but then it
couldn't go over backwards too far. The container overhang was 23 ft over
the truck bed, and about 32 ft over the back wheels. A challenging day, but
we made it! In high Def at 6:22 you can see the left front tire come off. A
Big Thanks to my brother-in-law, daughter, son, and nephew for all their
Fifth Wheel RV - Simulation of weight transfer under hard braking
What happens when you apply the brakes aggressively while towing a fifth
wheel trailer? Does the front of the trailer push down on the hitch and the
rear axle of the truck? To find out, I ran a simulation in Carsim 7, using
a full-size pickup model, and a model fifth wheel trailer. The loaded truck
in the simulation weighs approximately 5600 lbs, and the trailer about 6500
lbs. Yellow tire force arrows show how much weight is on the tire during
the braking event (the vertical arrows), and how much braking force the
tires are providing (the arrows pointing to the rear).
Brakes are applied at 0:17.
The results of the simulation show that the truck is able to stop much more
quickly than the trailer, even with properly adjusted trailer brakes, so
the trailer actually pushes forward on the hitch. Combined with the forward
weight transfer of the truck itself, this means weight on the rear wheels
decreases significantly under hard braking; enough that the trucks ABS is
activated for the rear wheels.
