Water Source
- can be a river, a channel or a bore hole. |
|
|
Water Supply System - Mainline pipes usually buried PVC pipes at 100-150-200 mm
diameter, ending with
a hydrant with a quick coupling connection. |
|
|
Power Requirements
- The self-propelled travellers use either
a water turbine, water piston or internal combustion engine mounted on the
reel/spool to power a winch and cable to tow the vehicle. |
|
|
Pumping System
- Simple or multi stage pumps with a
pressure rate between 3.5-13 bar, based on the size of the machine. |
|
|
Filtration Method - Filtration is not necessarily required, because of the big nozzle sizes (14-37.5
mm). In the case of the boom system a sand or screen
filtration is required based on the nozzle sizes of the sprinklers. An inline, self cleaning filter is usually fitted
to each machine to protect the valve and the drive unit. |

Equipment Description |
|
|
Sprinklers and Booms - The big gun sprinklers can be with
single or double nozzle with a flow rate range of 14-143 m3/hr
with the hose diameter of 40-140 mm at a connecting pressure ranging between 3.5
to 13 bar (see
pictures).
Booms can have a choice of pressure
regulated spray jets, rotators or spinners and
drop pipes. Also can be mounted with end guns (see
picture).
Spray booms
apply a particularly fine mist and operating on a
low pressure (see
picture).

|
Required Pressure - Connecting pressure at the
hydrant for Hard
Hose Travellers is 3.5 - 13 bar, for Soft Hose Travellers is 3.5 - 8 bar
and for Boom Irrigators is 1 - 4 bar. |

Automatic Control System |

Topography
- The traveller system can be used on
topography ranging from level to rolling and irregular. It can be used in
fields that have some obstacles, such as power line poles, trees or
buildings. Can be used on different odd shaped fields and most soil types. |
|
|
Application Efficiency - Under proper operation and management the
application efficiency can be up to 60
- 75% for HHT and SHT and up to 75 - 80% for the Booms. |
