Metallic zinc-coated spans are mounted 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
1. Galvanized pipe 8", 6 5/8", 5 9/16"
2. Galvanized pipe with poly lining 8", 6 5/8", 5 9/16" for special water

This 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.

Coupler two options
1. Traditional UMC coupler (left): no longer used
2. UMC C-X Coupler (right)
Units come preassembled
Universal design
Simple one wrench installation
UV stabilized flexible design

Gear box two options
1. Cummins standard (left):
Material: Grey Iron HT250
Shaft Material: high-strength forged steel
Worm and gear pressure angle is 14 1/2 degree
2. Rainfine heavy duty (right):
Material: Ductile Iron HT300
Shaft Material: Steel 45

Worm and gear pressure angle is modified
Significant improvement over standard models
Specially designed for use in warmer climates where
the pivot is used over 300 days per year

Tire two options
1. Rubber tire:
11.2×38: Good clearance and flotation
14.9×24: Tubeless tire 4ply, for heavier and longer spans
16.9×24: For longer spans more flotation
2. Plastic tire:
Rim: 10×38 with plastic pads (16 pcs×4kgs each)
Similar size with 14.9×24 rubber tire
Never flat / UV protection
Pad replacement / Non maintenance

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

We use automatic welding to make high quality and uniform span pipes. Using form drill technology developed in Germany gives gooseneck pipes a strong connection to pipe outlets, reducing any damage to the gooseneck when the sprinklers vibrate.
