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.

Gooseneck:M X M, M X F, M X B, Furrow arm and standard

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.

Corner control system for end gun
The end gun can switch on/off by solenoid valve when pivot moves to four corners. This valve is controlled by the switches in the pivot center.

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.

This is an optional part when water is full of dirt. Normally each pivot needs one filter. The picture on the left below is a cluster system with 3 filters for 3 pivots nearby. The left second picture is the filter system being used together with segmented filter for drip irrigation.

Due to the objective factors such as the terrain, obstacles, house and so on, the pivot cannot work a full circle (360 degrees). This system can control the pivot to stop/reverse automatically without manual control.

Install a barricade on the last tower of the pivot, when the touch arm hits the barricade, the pivot can stop and reverse automatically;
This system include control box, sensor arm, traverse arm, cable and springs;
Safety and crash prevention;

Each span parts are packed into one wooden box with clear packing list. This makes it easier for installation.
All wooden boxes are made of export material.
500m fixed pivot(9 spans) can be loaded into 1 x 40’ HC container.

We will dispatch our engineers to organize the installation work but the owner will organize labors. Normally one 7 spans pivot needs 8 labors working 1 week for installation.

We will ship 2% spare parts together with the equipments in containers. The items of the spare parts will be listed on the contract.
Our local representatives or dealers will help farmers to replace the damaged parts when necessary.
