Center Pivot 7000, 8000, 8120 Series 25
OVERVIEW
Alignment
There are 3 types of span alignments available,
Standard, Modified and Pivot floating alignment. See
Figures 25-1, 25-2 and 25-3.
The type of alignment used varies depending on the
length of machine, type of field and other application
requirements.
General machine length guidelines are listed below:
• Standard alignment for machines up to 1500 ft
(457 m) long.
• Modified Alignment for machines 1500 ft to
2000 ft (457 m to 610 m) long.
• Pivot Floating Alignment for machines 2000 ft
to 2800 ft (610 m to 853 m) long.
The last tower is the controlling tower. As the end
tower moves, all of the other towers move to maintain
straight alignment.
When the last tower moves, it creates an angular de-
flection with the next intermediate tower, this closes
the run microswitches and causes the next interme-
diate tower to move.
This cycle repeats itself throughout the length of the
entire machine.
The result of these cycles is that any tower can be
moving at any time, depending on its relationship
with the next outer span.
