INTRODUCTION

The NAVI-TRAC LT can be configured as a Hip End, Gabled End,
or Clearspan unit, as described below:

20’ NAVI-TRAC LT HIP END UNITS

The 20’ wide NAVI-TRAC LT frame configuration is based on the
hip roofed square tent shown at right. Hip bars connect corners
to the peak, and rafters connect eave bars to the peak. The
square tent can be extended into a rectangle by adding 10’ or 15’
bays consisting of parallel beams connected to the hip ends and
to each other by ridge bars, purlins, and eave bars.

70’

SQUARE TENT

FRAME

When the overall length
of the unit exceeds 60 ft.,
an X-cabled bay must be
added for each additional
60’ of length.

20’ NAVI-TRAC LT GABLED END UNITS (AND HIP-GABLED & HEX-GABLED UNITS)

The 20’ LT can also be supplied and installed as a gabled end tent consisting of a series of parallel beams interconnected
by ridge bars, purlins and eave bars (see the Appendix I). The hip end, gabled end & hex end versions of the LT
are guyed units that depend on staked, ratcheted guy webs at legs and corners for their stability. All three versions are
supplied with uprights adjustable from 8 ft to 10 ft high, with the gabled end unit requiring at least one bay of X-cabling.

20’ NAVI-TRAC LT CLEARSPAN (CS) UNITS (Gabled End Configuration only)

By adding appropriate additional X-cabling, and hinged Base Plates, the 20’ NAVI-TRAC LT can be converted into the 20 ft
NAVI-TRAC CS, a clearspan unit which is installed without external guy webs (see Appendix 2).

NAVI-TRAC LT INSTALLATION SAFETY GUIDELINES

Your own installation techniques will evolve to fit the varied needs of your clients, the experience level of your installation
crews, the nature of other tentage that may be common to the installation site being planned, and the equipment that you
may have previously available or with which you feel most comfortable. Whatever techniques you adapt for your crews, we
encourage you to keep safety utmost in mind.

Please read through this assembly manual completely before beginning your installation. Be sure the proper equipment,
crew and safety precautions are in place. We hope that you enjoy the design features of the Navi-Trac Lite®
each time the unit is installed.

1. It is recommended that workers wear safety shoes and hard-hats on site.

2. When moving frame sections by hand, use proper lifting techniques to protect the back, and avoid pinching
fingers while making hardware connections.

3. Be sure all workers are cautious and attentive to the falling paths of frame sections being raised or
lowered.

4. Be aware to avoid contact of frame sections with any overhead power lines near the site.

5. When anchoring the structure, avoid all underground power lines and gas lines or other utility easements.

6. Keep site clear of debris to avoid tripping, especially while carrying frame parts or bundles of fabric.

7. Do not drag bundles of fabric on concrete, asphalt, or ground as this can cause damage to the fabric from
abrasion through the bag.

8. Do not climb onto the fabric “roof” of the structure. When necessary, work safely from a ladder of
appropriate size.

9. When standing frame sections to vertical, or when lowering, use a smooth motion and have other
workers “foot” the base of the section to avoid slippage along the ground.

10. When installing gabled end units, be sure all beams are stabilized either by safety guys or cross­ cabling until connected to a section of the unit that is already stabilized in this manner.

11. Pay close attention to the proper use of the Navi-Trac Frame Jack (see Page 9). Use care in position
the jack carefully to maintain proper balance points in relation to weight, wind, and terrain.

12. Before installing fabric, be sure the frame is safely guyed off against the windload the fabric will transfer to the
frame (in the LT and Gabled LT). In the Clearspan (CS) units, be sure X-cabling is in place.

13. When liner ropes are installed on the frame during installation, leave these ropes partially coiled to avoid
tangling in them during frame assembly and standing.

14. When assembling the LT Gabled End units or the Clearspan (CS) units, be sure to safely stabilize the first
standing beam by using the safety guys supplied and the techniques described in Appendix page X-1b.

15. When installing a unit in which the overall length exceeds 60 ft., add one extra X-cabled bay for each additional
60 ft. of length. To meet design loads, no more than 60 ft. of consecutive length can remain non-X-cabled.

16. Notice that the Clearspan configuration has a narrower bay spacing and extensive X-cabling, especially
in the lower roof area in order to supply the stability needed to omit external guying. Do not install standard
Hip Lt or Gabled LT units without safely guying them out before fabric installation.

17. The installation method described here requires coordination of tasks between workers. A safe installation is
dependent on that coordination. Please work cooperatively as a team.

18. Inspect Site! Consult your local utility locator service or the National Utility Locating Contractors Association
(NULCA) prior to installation. Prior to actual tent assembly, be sure to look up, down, above & below for obstacles,
pipes, wires, trouble, etc.

REQUIRED DISTANCE OUT BETWEEN FRAME UPRIGHTS AND STAKE
LINE IS EQUAL TO THE UPRIGHT HEIGHT.
(FOR EXAMPLE, 8’ UPRIGHT = 8’ STAKE-OUT DISTANCE.)

ground as far as possible.

42” Stake driven through
stake plate. Stake must be
driven into ground as far as
possible. (1) per upright as
