Linear 4RMVE - Ditch-Fed
The Ditch-fed laterals - 4RM1, 4RM1-2 and 4RMVE) - are water fed through a lateral or central ditch. The water is directly pumped by self-cleaning strainers and an embedded pump unit that can be electrically or diesel powered. The electric energy can be also produced by a generator. These totally automatic machines can have extraordinary path lengths and cover oversized surfaces.
The laterals are moving irrigation systems to irrigate rectangular parcels. On these machines, there is no fixed anchor point to the ground; therefore, the lateral must support the mechanical pressures of the moving loads. Hence, the cart frame is made in S275 galvanised steel in compliance with the NF EN ISO 1461 and it is equipped with an electric management system in compliance with the NF EN909 February 2009 + A1. We chose these top-quality components to make Otech's experience known as global leader in the production of laterals
Swivel elbow power supply
The swivel elbow allows the connection of the polyethylene or flexible hose on the cart and the setting up of the buckle at the time of the inversion at the end of the parcel in order to reduce the human interventions on the machine.
Upper 90° elbow
The rotating upper elbow is mounted on bearings to balance the loads on the cart axis, simplifies the rotation while ensuring a maximum alignment precision.
According to the needs, the supply hose can be in polyethylene or flexible with a diameter adapted to the machine needs.
