Product Overview
▂▂▂▂
The canal-Fed Linear Irrigation System consists of a traveling vehicle, span section (including spray truss and tower), cantilever, and an optional tail gun system. It irrigates by drawing water from a connected channel during operation. As the vehicle and spans move in parallel in the same direction, it provides back-and-forth irrigation in the fields. The trajectory is linear, with a rectangular coverage area, making it suitable for long, narrow plots with a length-to-width ratio of 2:1 or greater.
The span section can be configured as a single unit or multiple combinations based on the size of the irrigated land. Different span sizes combined with cantilever pipes allow for machines of any length, with a single machine capable of controlling an area from 9.2 to 100 hectares. Sprinkler heads can be customized according to local climate conditions and planting needs, with irrigation intensity ranging from 4mm to 50mm.

Product Features
▂▂▂▂
1. Long Service Life: The main structure has a lifespan of over 20 years, providing long-term benefits from a single investment.
2. High Structural Strength: The materials used for the span are robust (see technical parameters for specifics), with a reasonable design ensuring overall rigidity.
3. Corrosion Resistance: All steel components are treated with hot-dip galvanization, with a galvanization thickness of 0.08 mm.
4. Even Water Distribution: Standard with NELSON R3000 spray heads, with options for other heads based on planting needs; water distribution uniformity exceeds 95%.
5. High Intensification: The investment cost per unit area is low, requiring no land leveling, and it can climb slopes of up to 25%.
6. Wide Applicability: Suitable for irrigating all outdoor crops, applicable to sandy, loamy, and clayey soils, and usable in both flat and hilly areas.
Technical Specifications
▂▂▂▂
Cross-body structure |
1.Pipeline |
Main pipe diameter: Ø219 (±2mm), Ø168 (±2mm), wall thickness: 3mm, length: 6.706m. |
2.Truss support |
The central tower's angle steel measures 100x100x10mm; the tower frame's angle steel is 100x80x8mm, utilizing four double "V" shape supports. All truss angle steel is 5x5x4mm or above, and the tower leg cross braces are 75x75x6mm. | |
3.Truss brace |
All components use high-strength round steel of diameter 20mm or above, made from 45# steel, and are hot forged in a single process to avoid cracking. | |
4.Fasteners |
The key fastening bolts in the equipment are all high-strength alloy bolts of National Standard Grade 10.9, while the secondary fastening bolts are all high-strength bolts of National Standard Grade 8.8. All nuts are metal self-locking nuts. | |
5.Cross connection |
The connection between spans uses external A38 aluminum safety covers, which are internally equipped with rubber waterproof sleeves. This design is aesthetically pleasing and provides double protection. | |

Control system | Main control box |
1.Displays operating status, performs real-time monitoring, and provides full-process fault alarms. |
2.Features automatic shutdown and reverse rotation functions, enabling sector irrigation (optional). |
||
3.Adjustable walking speed for the rear span of the sprinkler. |
||
4.The box has dual dustproof and waterproof features. |
||
5.A lightning protection device can be installed as needed. |
