Tie-down instructions
All park trailers should be securely anchored
to the ground with 6 tie-downs and ground
anchors (minimum 3 per side), to resist the
sliding and overturning effects of high winds.
Where tie-downs are required, it will be
necessary to follow the instructions herein.
Frame tie-down procedure
All park trailers are equipped with tie-down
attachment provisions on the main "I"-beams
(See Fig. 10.7). Any one of the three methods
featured may be used.
In the tie-down system, it is important to
use materials of proper design and of
adequate
quality.
specifications contained herein should be
considered as minimum requirements.
Materials not furnished with the park trailer
which will be necessary to complete the tie-
down system must meet the requirements set
forth below. Such materials would include:
1. Cable or steel strap with a breaking
strength of at least 4,725 pounds, e.g.
galvanized aircraft cable at least 1/4" inch
in diameter or Type 1, Finish B Grade 1
steel strapping, 1 1/4 inches wide and
0.035 inches thick, conforming with F.S.

2. Galvanized connection devices such as
turnbuckles, eyebolts, strap buckles and
cable clamps should be rated at 3,150
working load minimum.
3. Ground anchors capable of withstanding
at least a 4,725 pound pull. Anchors must
be installed as specified by the anchor
manufacturer.
THE UNIT MUST BE IN ITS FINAL LEVEL
POSITION PRIOR TO TYING IT DOWN.
The procedure for tying down the park trailer
is as follows:
1. Position and install the ground anchors to
line
up
with
the
brackets.
2. Connect the straps to the frame and
ground anchors.
3. Tighten the straps using the tensioning
device provided with the ground anchors.
Use caution to avoid over-tensioning the
straps as this may pull the trailer off the
piers. It is recommended that all straps be
tightened only enough to remove the
slack. Then, after all THE straps are
installed and the slack removed, tension
the straps.
4. The strap tension should be rechecked at
frequent intervals until all pier settlement
has stopped.
During the re-leveling process, do not jack
the park trailer against tight straps.
