1. Pivot Point
A lateral move system using a hose feed works in a linear movement to irrigate a rectangular area. Unlike center pivot systems, where the area irrigated depends only on the length of the machine, the area irrigated by the lateral system is determined by system length and travel distance.

Water is fed to the irrigation system by a flexible hose attached to the machine. The size of the hose is 6’ and 8’. The length can stretch from 1 span to 7 spans, though not more than 7 spans because of the hose weight limitation 450m length. The hose feed system requires hydrants and an underground pipeline.

The lateral move center is the only irrigation machinery which can water all of the land. In square patches of land, each span is parallel with the land so there are no blind angles and the irrigation ratio increases to 99%.

3. Spans
Metallic zinc-coated spans are installed on intermittent towers, each with two wheels, an axle drive unit with electric gear motor, and gearboxes on wheels; the electronic block of the system of the equalization and checking.

The truss design is the most important part of pivot irrigation systems. That’s why Rainfine precisely calculates the structural mechanics and test are pivot systems in tough conditions. Our pivot structures are durable enough to withstand 20 years of work without bending or breaking.

Two pipe options

The flexible joint design makes the pivot strong enough and flexible enough to encounter rolling or hilly terrain while in motion. Because the aluminum coupler will break if the spans are not properly aligned, causing water to leak and water pressure to drop, we’ve designed the control panel to switch off the system and stop the machine when the water pressure lowers. Rubber pipe fittings reduce water friction and resistance.

We use a high frequency electric heating system to heat both ends of the steel rods and a head forging machine to form them. When the rod is cut, the steel rod and the headed part have the same molecular makeup. This truss rod can withstand 60,000psi. We use 22mm diameter rods instead of 19mm, making our truss rods stronger than others on the market.

5. End Gun
Corner control system for end gun
When the pivot moves near corners, the end gun will switch on/off by solenoid valve so it can water more area. This valve is controlled by switches in the pivot center.

6. Sprinkler
The vast differences in crops, soils, farming practices and climatic conditions worldwide, coupled with the availability of water and energy resources, requires a range of center pivot sprinkler performances. Our sprinklers are designed to simplify the variety of choices into one basic and versatile group of center pivot products.

7. Chemical Injector
The chemical injector has a capacity of 85 to 500 LPH and a maximum pressure of 12 bar. Measuring accuracy is /- 2% with a flow rate of 10%–100%.

8. Multiple Filters
Though pivots only need one filter, multiple filters are good optional parts for when one filter fills too quickly with dirt. A cluster system composed of several filters can often be used for more than one pivot. For more effective drip irrigation, clients can choose segmented filter system.

9. Auto Reverse and Stop System
Due to factors such as the terrain, barns and houses, and other obstacles, the pivot may not be able to work a full circle. An automatic stop and reverse controls the pivot to avoid collision. A barricade on the last tower of the pivot works so that when hit by a sensor arm, the pivot will stop and reverse automatically. This system includes a control box, sensor arm, traverse arm, cable and springs, and collision prevention.

10. Shipment
Each span is packed into one wooden box with a clear packing list and instructions for easy installation. All wooden boxes are durable for safe exporting. A 500m fixed pivot (9 spans) can be loaded into a 1×40’ HC container.

11. Installation
We will send our engineers to supervise installation. Normally one 7-span pivot needs eight people working one week for installation.

12. Spare Parts and Guarantee
We will ship 2% of spare parts together with the equipment in the container, whichever of the spare parts were listed on the contract. Our local representatives or dealers will help farmers replace damaged parts when necessary.
