PIVOTS and LINEARS
1 / 12Pages

OTECH company In 1993 OTECH bought IRRITEC (a subsidiary of IRRIFRANCE) and its plant in Puyoô (south-west France) has been manufacturing pivots and linears since 1980. Thanks to its industrial installations and to its know-how, this plant has the capacity to produce more than 3000 spans and more than 400 linears per year. OTECH and its subsidiary OTECH40 (based in Mont-de-Marsan) employs eighty people who are committed to the development of our products. Production at OTECH is focused on two key areas: the conservation of water and energy and sustainable development. The Puyoô plant...

Adapted solutions to optimise water and energy use Pivots and linears can be adapted to suit any surface from three to several hundred hectares, taking into account energy costs, water requirements of the crop, and labour. OTECH emphasizes the principle that 'by using the right pivot and right nozzle, you can achieve an evenness of irrigation of 90 to 95% without needing more pressure and energy than the 'drop by drop' system. Continuous innovation During the last few years, OTECH has developed the DOSITECH (remote management system), the HD Pivot (hydraulic), the retractable overhang and...

Pivots are irrigation systems consisting of one or more spans which rotate around a fixed point anchored to the ground. The spans turn repeatedly around a fixed central point. They are simple to use and require little intervention. These machines are both reliable and excellent value for money. The H.D. Pivot (hydraulic system) The spans rotate less than 360° and therefore maximize the irrigated surface area when there is an obstacle (farm building, tree, pylon etc.) situated in the middle of the field, or where the shape of the field does not allow full rotation. An automatic reverse...

(by tractor) This machine is equipped with a tower on swiveling wheels and a central unit on a moveable chassis fitted with a beam. Once the wheels are aligned with the span's axle, the whole machine can be moved by tractor. This type of pivot allows a reduction in the cost per hectare irrigated by increasing the area covered by the same machine. (self-moving) The Speedy Rain is a machine which can be moved autonomously. It operates as a pivot during the irrigation phase by rotating around its central tower. During the movement phase it becomes more like a linear. Requiring no tractor, the...

LINEAR MOVES Linear moves are systems consisting of one or more spans which can be used autonomously. The water supply arrives via a pulled pipe or by drawing water from a lateral channel. The electricity supply comes from a pulled cable or from a generator These machines can be adapted to suit the different layouts of fields by following different circuits - linear or combined (linear and European leader in this field with more than 2000 linear moves This machine allows a 'back and forth' irrigation via a linear of five spans maximum. This model is ideal for small to medium- sized...

'Back and forth' irrigation with a linear move Two lines of spans mounted on both sides of the motor which allow the flow to be spread out and reduce water loss • Hydraulic water supply • Tower on a chassis with 4 motorized wheels • 2 jointed axles for a better adaptation to the terrain • Can accommodate an electricity generator • Possibility of hydraulic water supply via a loaded gen-set and a self-cleaning strainer by drawing water from a lateral channel at rates of up to 800 m3/h • Furrow guidance system This model can perform combined programs (linear and circular) thanks to its...

CONTROL SYSTEMS OTECH machines are controlled by an intuitive control panel with electromechanic components which are robust and reliable. Optional control tools can be added: - allows you to directly adjust the desired application rate in mm by setting the required program time. - allows you to adjust the water application in several zones via a tactile colour interface. Among a multitude of other functions, the machine can be operated from a PC connected to the internet and receive alerts via GSM. These small accessories play an essential role in the operation of an irrigation system....

SPECIFIC MACHINES Swingable overhang With a maximum length of 30 metres, the swingable overhang optimizes the irrigated area by avoiding obstacles such as houses, trees and pylons. The whole overhang is mounted on bearings on the last tower allowing a rotation of a quarter turn, and stabilized with a central weight. The automated rotation is synchronized with the start / stop of the sprinklers and end gun, therefore allowing the irrigation of areas inaccessible to a standard machine. Offering maximum flexibility, the folding span is the ideal solution for bypassing obstacles in the middle...
