There are two options to build the ditch:
1. Cement bricks
Conserve water (e.g. reduce friction loss from earthen ditches)
Minimizes irrigation-induced erosion and invasive weed growth
Work well with a gravity system; No pumping is required
Maintenance minimal compared to a dirt ditch
Can work on any field
1.lateral move center
Water is fed from the ditch along the irrigation machine. This machine is lateral move, ditch feed system.
As the ditch can supply big quality of water, this system can be made longer. If the system is designed to have two wings, the span can be longer than 800m. if the machine can walk 2000m, the total irrigated area could be up to 160ha.
The capacity of pump and diesel engine will be calculated by the size of the land and the water application rate as well as the working speed of the machine.
Pump and diesel engine are installed on the cart of the center. Alternator is installed at one end of the diesel engine to produce electric power for the machine.
Water suction pipe and boat are installed on one side of the cart to take water from ditch.
lateral move center:
Leg angle size: 100mmx100mmx10mm thickness
Riser : 8”x3mm
Elbow: two wings 8”x 3mm thickness
It is a special design to form a solid anchor for even longest system.

2.diesel generator
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.
3.spans
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 parts on pivot part 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.
Two 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
Galvanizing Kettle:
Inside Dimension: 14,000 long x 1,200 wide x 2,000 mm deep
By W. Pilling of Riepe, Germany, the world’s leading kettle manufacturer.
50mm wall thickness, European Special Grade Plate (see analysis below)
Typical Analysis: C, .08%; Mn, .5%; P, .02%; S, .02%; Si, traces only
Zinc Volume of Kettle: 90 tons
Weight of Kettle: 25,150 kgs
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.
Two options:
1. Commins 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
150% improvement compare to the standard
Special designed for Sudan market where the pivot being used 300 days per year
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 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.
Tower box:
Contactor rated 600V at 16 amp min.
Alignment switches rated 277V at 15 amp tested to 10,000,000 cycles.
On-Off switch rated 600V at 10 amps.
4.overhang
The high yield strength overhang cable is used in longer overhang. This design can help farmers to increase yield with less investment.
6.sprinkler
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.
