Operation of Side Roll
Side
Roll is an aluminum pipe (lateral) mounted on large wheels. The
Side Roll
irrigates in place (does not move while irrigating) and it is moved from
position to position between irrigation runs. An
air-cooled gasoline engine provides the required power to move the aluminum
sprinkler line across the field. The aluminum pipe is connected to hydrants
by a flexible hose. The hydrants are usually spaced every 18 meters (60')
along the supply line (mainline). The supply line may be located along one
edge or in the center of the field.
The Side
Roll
is very simple to operate. When an irrigation run is
finished, the operator simply turns off the mainline valve and disconnects
the flexible hose. The drain valves automatically drain the pipe due to the
reduced pressure. The operator then starts the engine and rolls the pipe
to the next hydrant position along the field,
reconnects the flexible hose, turns on the water and starts the next
irrigation run. The whole operation of repositioning takes about 20 minutes
for a single person. When the
Side
Roll has reached
the last position at the end of the field, it is driven back to the starting
point for the next irrigation cycle.
