RKD Circular Irrigation System: The Sturdiest Pivot. The pyramidal structure of the RKD central pivot is built up with galvanized-steel angular profiles and the bolts are anchored to a square reinforced concrete platform. Both of these result in the RKD pivot’s having a remarkable sturdiness and stability which allow it to handle the turning movements of the machine. The pivot is water-fed through a vertical inlet pipe and elbow, both made of galvanized steel of 8 5/8” (219mm) diameter, except model 450, which has a vertical pipe of 5 1/2” (139.7 mm) diameter. It contains a 13-way external electrical collector ring and an access ladder. The standard height of this pivot is 4,220m from the base to the centre of the elbow, and can be bigger in particular crops such as sugar cane, etc.

This works similarly to the center pivot, but it can be transported automatically in order to irrigate 2, 3, or more positions, providing a high increase of irrigation area with only one machine. This is a self-propelled system and neither a tractor nor any other kind of machine is needed to change its position. It moves sideways, and may be guided with alignment performed by means of a furrow or a cable; all required security systems are provided. It does not require the turn of the tower ́s wheels in order to move. The revolving main cart has two driving wheels, used for the circular function, and it is performed by rotating the wheels 90º once the cart is lifted with the hydraulic lifts installed in it.

RKD Lateral Systems are suitable especially for irrigating rectangular plots and are guided by a precise system of alignment by means of a furrow or a cable. The cart is mounted on two or four driving wheels and the feeding of the equipment can be accessed by means of a hose connected to one or more hydrants, depending on the dimensions of the plot and the volume of flow it must provide; or by means of a motor-pump group fixed on top of the main cart, which takes the water directly from a ditch to feed the system.

RKD hippodrome systems have been designed to irrigate square, rectangular or unusually shaped plots, allowing lateral irrigation and making the turn possible by pivoting at one or more points, internal or externally. They are able to irrigate when necessary, without requiring the anchoring of the central cart.

For water conduction in the irrigation systems located in tertiary, secondary, and main tubing’s of high, medium and low pressure. Very suitable and used for irrigation using tape. The diameters that are employed vary from 40 to 200 mm. and the working pressure from 2 to 12 bar. (Depending on the hose’s diameter).
