LAYOUT BUILDING POSITION ON SITE
To fully use the rolling feature of this building, you must
provide adequate distance for the building to move.
Minimum distance to clear the original location of the
building is twice the building length.
For example, if the building is 48' long, site must be at
least 96' long to allow the building to roll from one position
to another. Building is equipped with enough 1.66" pipe to
create a track that is twice the length of the building frame.
To move the building in the same direction, track can be
disassemble, reassembled, and attached to the desired
end of the track that the building rests on.
The information that follows shows using ground cloth
(included) to prevent vegetation from growing around
the track path. Basic steps to layout the track include the
following:
1. Determine the best position on the site for the
assembled building. Consider where the rafters will be
assembled and how these will be transported to the
frame assembly area.
2. A level site is required for best results. Remove
debris, obstacles, and other objects that can prevent
the 1.66" track pipe from running tight to the ground.
If necessary, prepare the track portion of the site by
leveling the bumps and hills and filling the ditches. The
straighter the track runs, the easier it will be to roll the
assembled building.
Allow 24" of clearance on each side of the track pipe to
more easily access the frame and frame anchors when
moving the building.
3. Roll out the ground cloth and stake the cloth to the site
using the fabric staples. Drive one (1) stake every 4'
along each outer edge of the ground cloth. See next
page for photos.
4. Locate the 1.66" pipe (166S099) used for the track.
Pipes are connected; however, joints are not secure
with any fasteners. Doing so will interfere with the metal
castors and prevent rolling. Joints can be secured with
a couple layers of duct tape if desired. Additionally,
pipes are not secured to the site.
5. Drive a couple of stakes to mark the width of the
building and the beginning of the track. Connect a few
pipes and place these in position on the site. Assemble
only enough to allow for the assembly of the first few
bays of the frame. Pipe can be added as the frame is
assembled. This prevents running over the track pipe
during assembly.
6. After setting a few track pipes in place, continue with
the assembly of the rafters and frame.
Photo shows stakes at the width of the frame and at the
beginning of the track positions.
