Hose-fed irrigation boom 4RM1-2

4-wheel2-wingfurrow guidance

The 4RM1-2 lateral has four drive wheels and enables the automatic lateral back-and-forth displacement of the machine to irrigate larger rectangular parcels. Like the 2RM1, it tows a hose that can become longer thanks to a higher pulling power. Unlike the 4RM1, the spans are divided on both sides of the cart. 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. Hose traction According to the needs, the supply hose can be in polyethylene or flexible with a diameter adapted to the machine needs.
