III. Load Placement
Load Placement
The image below shows the correct setup that should be used with the PTT3, as well as where to
place the load. These trailers should consist of one wheel axle. When the trailer and the PTT3's cou-
pling are attached to each other, and the PTT3's arm is raised, the trailer leg will be lifted off
the ground.
As mentioned above, trailers should consist of one wheel axle. If there are two axles and the floor is
uneven, the front wheel will be lifted up by the PTT3 and overload the wheels. Uneven floors put the
trailer coupling at risk of unfastening and can disconnect from the trailer.
The PTT3 has a maximum load capacity of 6,614 lbs on the drive wheel under normal conditions.
The load capacity depends on the configuration of the load. Max capacity could be under 6,614 lbs.
depending on if there is a swing bearing or a lift cylinder. Contact Hedin USA if you unsure of your lift
capacity.
The drive wheel needs ground force on it to make sure friction between the floor and wheel provides
the traction required to perform the transport.
The load center has to be in between the trailer's wheels and the PTT3's drive wheel. If not, there is
a chance the load could overturn.
Heavier loads must be balanced on the trailer - see picture below.
