Martin Engineering M3404-05/12
If air cannon is mounted more than 6 in. (152 mm) above
ground, install restraining cable to secure air cannon to
storage vessel. Without restraining cable, air cannon could fall
and cause injury.
Do not use restraining cable to mount air cannon to storage
vessel wall. Purpose of restraining cable is to keep air cannon
from falling should it come loose from vessel wall, not as
primary means of securing air cannon to wall.
Do not use angle iron or support ring to secure air cannon
rigidly to storage vessel. If restrained too rigidly, tank cannot
flex and cannon can fail.
1. Weld D-ring (A, Figure 12) onto storage vessel (B) with 1/4-in. (6-mm)
field weld.

2. Insert wire rope (C) through D-ring on storage vessel, making a 3-in.
(76-mm) loop. If wire rope supplied with air cannon is not long enough,
loop and clamp it to an additional cable and attach additional cable to air
cannon.
3. Clamp wire rope with one cable clamp (D) as close to loop as possible.
Place another cable clamp 1-3/4 in. (44 mm) from first clamp.
4. Leave at least 1 in. (25 mm) of wire rope on dead end.
5. Gradually tighten nuts alternately and evenly to 15 ft-lbs. Leave 2 to 3 in.
(51 to 76 mm) slack in wire rope.
6. Go to "Connecting air supply to air cannon."
