WARNING: Never get between the dump truck and the paver when
attempting to engage the two. Serious injury or death could result!!
WARNING: Never attempt to tow the paver before first engaging the
hitch arms. Serious injury or death could result!!!
SCREED ASSEMBLY
standard paving width of eight feet, a nd can b e hydraulically extended to fourteen feet.
This is a very unique screed in so much that the entire mat surface is compacted. The screed
extensions are not strike offs, they have compacting wear plates attached to them.
The screed depth controls are attached to the hopper frame by two spherical, self-
aligning, cast iron nuts. This is to insure effortless depth adjustment regardless of the paving
setting. The screed assembly may be adjusted to a three inch crown or three inch invert.
The crown adjustment is made by ratcheting the adjustment lever on the middle of the screed.
Because of the tight machining tolerances of the connecting joints between the screed
and the hopper, accuracy of the mat thickness can be accomplished. When an adjustment or
setting is made on the depth control screw, a rapid change in mat thickness is accomplished
and can be maintained with ease. In most cases, when a desired mat thickness is obtained,
little or no compensation will need to be made.
UNDERCARRIAGE
The independent mounted boggy assemblies contribute largely to an accurate and
successful paving operation. The independent boggies are precisely located, and mounted
into the hopper frame. This offers the capabilities to pave at different depths on either sides
of the screed assembly and offers an accurately paved mat.
To change the paving depth from five to ten inches, in lieu of the standard zero to five
inch setting, it is necessary to remove and flip the boggy assemblies over, and reinstall them
into the support legs.
Two double acting cylinders power the hitch arms that attach to the dump truck to pull
the paver. The hitch arms have three position adjustments for the rim rolls and side rolls that
will permit attaching to most trucks.
