Product Description

As the name suggests, center pivots irrigate in a circular pattern around a central pivot point. Most center pivot machines are electrically powered, using either a generator or a public power source.

Pivots use both 120 and 480 volts of alternating current (VAC) to operate. 120 VAC is used as the control circuit, powering the safety circuit, the forward and reverse movement of the pivot, and, more precisely, the movement of the Last Regular Drive Unit (LRDU). The 480 VAC is the power circuit and supplies the needed energy for the drive units to move.


The pivot's control panel operates the main functions of the machine. Depending on which control panel the pivot has, the controls will be different, but the way the pivot operates is the same. When a command is entered into the control panel, an electrical signal is sent down the pivot until it reaches the Last Regular Drive Unit. 480 VAC then travels through a motor lead cable from the tower box to the engine. The LRDU moves, either forward or reverse, as the control panel indicated.

When a pivot moves, it is led by the Last Regular Drive Unit. The LRDU moves until the switch arm, connecting the last span to the second-to-last tower, is pulled to an angle that activates the next tower. Both towers then move until the next tower is activated, and this continues down the pivot until all towers have moved.

There are 2 microswitches in the tower box because one is used to send signals to the drive motor to make the drive unit run, and the other controls the safety circuit in case the pivot comes out of alignment. If a pivot comes out of alignment, the safety microswitch will break the safety circuit and shut down the machine.


Tower Box - Located at each drive unit is a tower box. This compartment controls the drive unit components, telling it to move in the right direction and for how long.

Irritech China supply Tower control box for center pivot irrigation system includes:
1)Intermediate tower box,
2)End tower box
3)Booster pump tower box,
4)Stall timer tower box (next to end)
5)Auto stop Auto reverse control box 
6)End of field stop control box
7)Guide tower box for Linear system
8)Central pulse towerbox

We have supplied these tower boxes to several centre pivot manufacturers around the world. In addition, they can be used on all other brands with our bolt or weld on conversion kits.


Irritech tower boxes use Honeywell micro switches, Schneider contactors and UL Recognized terminal blocks. We have designed and developed an indicator light underneath the tower box which will provide an instant visual alert if there is a break in the safety circuit.

All of our tower boxes carry the UL label and include the tower box stiffening bracket as standard equipment.
The tower box is constructed of white, heavy-wall UV stabilized thermoplastic with a galvanized steel base. Features include a stainless steel cam shaft and adjustable, moisture-resistant directional micros. The rigid base and oversize cam spring enhance the machine alignment characteristics to reduce structural stress.

FAQ

1.What kinds of pivots do IRRITECH produce?

Our products can be classified into three categories: fixed center pivot, towable center pivot, and lateral move system.
The main difference between these systems is their mobility.
1.The fixed system has one stationary end of the machine, while the other moves clockwise by motorized wheels.
2.Towable pivots have three or four wheels assembled at the center of the pivot, making it towable by tractor.
3.Lateral move systems work in a linear fashion, driven by motorized wheels. Unlike center pivots, where area is determined by the length of the machine, lateral move systems depend on both system length and distance traveled.

A towable center pivot should be a maximum length of 300m for safe towing, but fixed pivots can be much longer.
Compared with both fixed and towable systems, lateral move systems depend on the source of water. Ditch fed machines recieve water from the built ditch. Hose fed machinery recieves water from underground pipelines with hydrants. For hose fed systems, the maximum length is 450m because connecting one hydrant to another incurs labor costs.

2.PIVOT DESIGN CHOICES

When purchasing a center pivot system one must select:

Mainline size and outlet spacing;
Length, including the number of towers;
Drive mechanisms;

Application rate of the pivot;

The type of water applicator.

These choices affect investment and operating costs, irrigation efficiency, and crop production. Wise decisions will result in responsible water management and conservation, flexibility for future changes, and low operating costs.

3.What is the warranty on your products?

Warranty covers our center pivot and lateral move systems up to 1 year concerning electrical equipment, and 10 years or 10,000 working hours for gearboxes and gear motors-whichever expires first.
We guaruntee 15year use concerning our galvanized eqipment against corrosion, and 3 years for our tires and rims.

4.How much does your equipment cost?

Our pricing depends on the machine you are looking for, along with several other variables. In regards to our center pivots, we have both fixed and towable pivots and lateral move systems available. We will need to know your preferred water source (ditch or hose fed), land data and the types of crops that will be irrigated. Given this information, we will also determine the necessary sprinklers for your system.

5.What are your payment terms?

We accept 30% down by T/T (wire) or 70% by L/C or T/T before shipment.

6.How long will it take to manufacture and ship a center pivot or lateral move system?

Time spent on each order depends on the quantity and specifications of your order. Some machines we have in stock, but special orders require more time. We can provide you a time estimate once we have adequate information concerning your order.
However, we can say that lateral move systems take a longer time to produce, especially if you require a ditch feed water source. Because they also require a main cart pump, diesel engine, and alternator, time also must be included for our suppliers.

7.Are these machines difficult to operate?

Our machines are very simple, and you will be able to learn their functions within an hour's time. Once you learn to operate the systems control panel, it will function automatically. We are also currently working on a remote control for our systems, which should be released soon.

8.Do center pivots and lateral move systems work on rolling or mountainous terrain?

Yes, both systems can work on rolling or mountainous land. Lateral move systems only work on up to 5% slopes, but center pivot systems will work on up to 20% slopes.

9.What is the auto stop/reverse system and when can it be used?

In certain situations, a pivot will not finish a full rotation due to obstacles in the field such as terrain, poles, houses, etc. Now the auto stop/reverse system is needed. A touch device is installed in the tower of the pivot, when hit by the rod connected, the pivot can stop/reverse automatically.

10.Can I use fertilizer device on more than one machine?

Yes, you can use our chemical injector on more than one machine such as center pivot and lateral move systems. The chemical injector is small and easily transferred by just one person. It can also promise the safety of livings, you can find the details on the introduction.

11.Can I use fertilizer device on more than one machine?

If your field is rectangular and you are not using a lateral move system, you may need end gun to spray the area uncovered. The corner control systems can control when the end gun is spraying, so that no water is wasted on covered land.

12.Is the diesel generator included in my quote?

Our diesel generator is only included with lateral move systems, otherwise we will quote with electric power. If you would like, we can include the generator in your quote for other systems.

13.If I need a CFR price, what should I do?

All we need is your destination port. Then we will provide a CFR quotation by adding the freight cost provided by our freight forwarder .
