WESTERN pivots utilize the “Bow String” span design, with a maximum length of 62m (203.5ft) between towers. WESTERN pivots offer different span lengths in order to adapt the lengths of the machine to the dimensions of the field. Spans with pipe size of 5” and 6-5/8” are available in the following lengths options: 38.2m (125.5ft), 44.2m (145 ft), 50.1m (164.5ft), 56.1m (184 ft) & 62.0m (203.5ft) In case pipe size of 8-5/8”, maximum span length is 50.1m (164.5ft). Span pipes are available in three different diameters; 5”, 6-5/8” & 8-5/8” with pipe thickness ranging from 2.8mm to 3mm. New truss joiner bracket design provides superior clamping force over the truss rod and reduces stress concentrations when compared with other leading manufacturers. WESTERN Truss Rods are made of high strength steel with hot forged heads on both ends for strength and toughness with two different sizes 3/4” and 13/16”.
The distance between two sprinklers in the span is called outlet spacing. WESTERN spans have three different outlets spacing. *2.97m (117”) *1.48m (58.5”) – Standard *0.74m (29.25”)
Available Ground Clearance
The distance from the lowest point at the span to the ground is called ground clearance. WESTERN spans have three different ground clearances to match different heights of the planted crops:
Low profile: 1.9m, (for shorter crops)
Standard profile: 2.9m (Most field crops)
High profile: 4.52m (Sugarcane)
