This is lateral move system or linear system. All the machines work in linear movement by motor driven tires to irrigate rectangle area. Unlike center pivot systems, where the area irrigated depends only on the length of the machine, lateral system area is determined by two factors: system length and travel distance.
The length can be from 1 span to 18 spans, normally more than 7 spans system is economical. Lateral move system is the only machine which can irrigate all land. In square land, all spans are parallel with the land, no blind angle. The irrigation ratio can increase to 99%.
Water source to fill the machine can be canal, concrete ditch, rivers, pond and well. The lateral move can be ditch feed and hose feed.

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 can be broken when the spans are not in proper alignment. This will case 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 punching machine to punch 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.
