With lateral move irrigation systems that use ditch feeds as a water source, there are two ways to build the ditch – with cement bricks or geomembranes.
1) Cement bricks
The advantages of cement bricks are that they conserve water by reducing friction loss caused by earthen ditches, minimize erosion and invasive weed growth caused by irrigation, are easy to maintain compared to dirt ditches, and can be used in any field. Cement ditch feeds also work well with gravity systems as no pumping is required.
The advantage of geomembrane ditches are that it’s ten times faster than laying precast slabs or in-situ concrete as no mixing, measuring or compacting is required and the cost of installation is up to 60% less. Geomembrane ditches also help to prevent weed growth and erosion, reducing maintenance cost.
1.lateral move center
In a lateral move center, water is piped from the ditch to the sprinkler. Because ditches provide a large quantity of water more of your field at one time. If the irrigation system is designed with two wings, the span can be longer than 800m, and if the machine is made to move 2,000m, the total irrigation area could be up to 160ha.
The capacity of the pump and diesel engine depends on the size of the land and water application rate as well as the working speed of the machine. Pump and diesel engine are installed on the center pivot’s cart. An alternator is installed at one end of the diesel engine to produce electric power for the machine while a water suction pipe and boat are installed on one side of the cart to pump water from ditch.

We can offer various diesel generators from 6 to 20kw for pivots. We can supply small diesel generators that most big brands do not with chinese best engine. We are able to supply any spare parts for these generators as well.
Metallic zinc-coated Spans rubber-boot united between themselves, mounted on support of intermediate towers-each with two wheels, axles drive unit from electric geared motor to Wheels gearboxes; the electronic block of the system of the equalization and checking.
Truss design is the most important part on pivot parts on pivot irrigation system. The structural mechanics are precisely calculated by computer and tested in tough road. It can stand 20 years long lasting work without any bending or breakings.

This flexible joint design can support all the strength of the pivot and maximum the flexibility of the pivot in rolling land. The aluminum coupler will break when the spans are not in proper alignment. This will cause the water leak and the water pressure loses. The control panel will switch off the system when the water pressure gets lower and stop the machine. The rubber boots can reduce the water friction and resistance.
We use high frequency electric heating system to heat both ends of the steel rods and use head forging machine to form them. When the rod being cut as the picture shows, you can find that the steel rod and the headed part are exactly the same molecular. This truss rod can stand 60,000psi yield strength. We use 22mm diameter rods instead of 19mm to make it stronger than other manufacturers.

We use automatically controlled welding Robot to do the welding for pipes to ensure the quality. The welding line is in perfect quality for the span pipe welded by Robot. We introduce Form drill technology from Germany and use it in our pipe drill processing system. This technology can help the gooseneck to have a maximum connection to the pipe outlet holes and reduce the gooseneck damages during the sprinklers vibrating.

The vast differences in crops, soils, farming practices and climatic conditions worldwide, coupled with regional differences in the availability of water and energy resources requires a diverse array of center pivot sprinkler performance. The sprinklers we choose for you are advanced designed to simplify the variety of sprinkler choices into one basic group of center pivot products.
