ST Pivot Sector
High and ultra-High clearance Pivot
The 4.80 m high clearance pivot suits for high-growing crops (sugar canes, arboriculture, etc.) and to pass above the obstacles (buildings, machines, etc.).
The pivot point is the center of the irrigated circle. Its function is to keep the span in the parcel center. Hence, it must withstand two main forces: a traction force of the moving spans and the weight of the first span. Besides the single resistance of each element of the pivot point, the global structural resistance of the assembly is essential. For this reason, Otech uses S275 top-quality steel and a NF EN ISO 1461 galvanisation to get a tried and tested structure, composed of an electric management system in compliance with the NF EN909 February 2009 + A1.
Electric collector with minimum twelve rings (25 A to 500 V) IP233 anti-UV watertight under cap, mounted on watertight ball bearing, triple reach contacts, terminal block, predisposed for additional rings and angular coder. French manufacturing on Otech concept
As standard, coupling with the first IP233 anti-UV watertight, span relieve pressures on the upper elbow for tough grounds. Galvanised steel coupler to protect two low-pressure lip seals against environmental threats (UV, sandstorms, etc.).
