points simultaneously consistent with the available
personnel and handling equipment. Speed of removal
of matting will be considerable y greater if disassemble y
takes place in the opposite direction of assembly; that
is, the female connector is removed from the male
connector.
MATTING REMOVAL WITHOUT
A GUIDE RAIL
In a SATS system where a guide rail is not used,
matting removal at points other than exposed ends of
matting requires removal of typical keylock sections
as the initial step.
The procedure for removal is composed of the
following steps:
1. Remove typical keylocks by loosening the
socket head screw at the first joint until it is free of the
lower thread (about 7/1 6 inch). Do not remove further
as this screw is self-retaining, and disassembly and
future assembly are accomplished from this position. If
the exposed end of the typical keylock is a cut end, that
particular section must be pried out or pulled out. If the
female end is exposed, the section may be removed
using the special removal tool. (See fig. 11-35.)
2. The backfill must be removed from the runway
approach aprons that may be accomplished as the center
portions of the runway are being disassembled.
3. The 90-degree connectors are independently
removable by sliding individual connectors lengthwise.
However, the mat disassembly procedure should be
planned so that the matting engaged on the 12-foot edge
is removed first. This cccurs, for example, where the
lateral taxiway matting (12-foot edge) meets the runway
(fig. 11-26), then 90-degree connectors can be removed
more easily than by sliding connectors lengthwise.
4. Tie-downs must be removed before parking area
disassembly.
5. Disassembly of a mat row may proceed from the
end with the overlapping mat. Remove the locking bar
from the adjaent mat by inserting a bent rod or wire
into the hole in the locking bar and pulling it straight
out. (See fig. 11-35.) The most efficient procedure
requires disassemble y in reverse order of assembly.
Therefore, starter keylocks will be the last component
removed from the runway. Remove the starter keylocks
by removing the socket head screws from each
adjoining starter keylock Insert the connector bar in the
starter keylock just removed to the second hole (the bar
will protrude 1 inch), and tighten the screw. Replace and
tighten the screw in the adjacent keylock.
MATTING REMOVAL WITH
A GUIDE RAIL
In a SATS system where a guide rail is used,
portions of the installation, other than the runway, may
be disassembled in the same manner as described
previously. However, the presence of the guide rail
prevents the removal of matting other than from one
end. Runway aprons that do not include guide rail
sections are an exception. These portions may be
removed at any convenient time after the backfill has
been removed. Removal of the runway matting and
guide rail must start at the same end at which the
runway was completed. In addition to the removal of
locking bars between the mats, the locking bars
connecting the mats to the guide rail must also be
removed. Removal of guide rail locking bars is
accomplished in the same manner as for mats. (See fig.
11-35.)
