Casella LL 125/500 Hard Hose Irrigator

CASELLA Fully Hydraulic Control Panel

This unique, cutting edge technology allows you to save lots of pressure that is lost to operate long range hard hose irrigators with turbine and longer than 400m hose.

On left hand side of the panel, the hydraulic control arms operate the trolley lifting mechanism, put the wheels and tow bar lifting jack up and down, rotate the hose drum around.

The hydraulic gear box in the middle spins the hose reel forward or reverse directions at desired speed.

Therefore, the irrigator does not rely on the water flow rate and pressure to be run efficiently and constantly at the same speed.

BUILT-IN HYDRAULIC SYSTEM

The gear box is directly connected to the cog wheel on the drum and it can be easily engaged and disengaged by rotating its leverage left to right.

Performing as:
- Hose rewinding speed can be adjust from 10 to 150m/h.
- Lever for the control of hose rewinding - stop - reverse rotation.
- Automatic stop in case of end of working and wrong hose rewinding.
- Automatic protection against PE hose breaking by a valve calibrated to the maximum allowable strain with regard to the PE hose mounted on the machine.

Simple, accurate, strong and easy to use hydraulic lifting mechanism for the trolley. It does not require any attachments to the trolley.

The standard trolley of this irrigator comes with 4 cement filled steel wheels, hight and width adjustable frame and 3" flanged sprinkler outlet.

Squad type hard hose irrigator's drum and frame with no plastic covers! Designed for tough conditions and longest life span in the market.

HYDRO-CONTROL 260

- Length of unwound hose up to 1000 meters
- Initial pause 0 to 99 min.
- Hose re-winding control 5 to 999 m/h
- Final pause 0 to 99 min.
- End of irrigation
- Automatic calculation of speed by programming the irrigation time. 

During irrigation the back-lit display shows: irrigator recovery speed in m/h, remaining length to be rewound, remaining time to the end of irrigation.

The largest diameters on all major connection pipes of the irrigator to save energy.

IDEAL SYSTEM FOR EFFECTIVE ENERGY SAVING

This irrigator is fully driven by a small (7 HP) diesel Yanmar engine for both hose rewinding and hydraulic control operations. The main advantage of this system over turbine driven irrigators is that it does not rely on water flow rate and pressure to run the irrigator, so the water power is completely and purely used for irrigation. The friction loss to operate this size of a machine is reduced by 25-30% with an average fuel consumption of the diesel engine of 300gr/h. This solution makes this system suitable for using hoses in large diameter and remarkable length (up to 700 m). Moreover, it is the only system allowing spreading of manures or waste waters at high recovery speeds (10 to 150m/h). Since, there is no turbine in the system, solid particules can be easily and directly laid down.

SENSOR FOR HOSE REWINDING SPEED MEASUREMENT

The ELECTRONIC COMPENSATION system keeps the rewinding speed constant irrespective of winding diameter and hose traction force. When the desired speed is selected on the computer the sensor detects the actual rewinding speed on the hose then the computer makes required adjustment on the hydraulic control valve to keep the rewinding speed at the desired speed during the machine's run time.

DISCHARGE VALVE
The machine comes with discharge shut-off mechanism. The valve is opened by an electric motor, when the computer of machine send the end of run signal. Since these machines are designed to work with high volume irrigation applications, using a discharge valve is safer than using a closing valve at the inlet of the irrigator for maintaining the pump's and main line's durability. 

When the valve is opened by the computer, long poly pipe attached to the valve throws the pressurised water to  5 - 10 m further to make sure soil around the irrigtor is dry. 

WATER INLET
Special care has been devoted to the design of water inlet by means of large diameter pipes and wide radius elbows to prevent any pressure loss..

OPTIONAL PTO driven purge pump would be very helpful to empty the hose before shifting machine from one spot to another one. Especially it is highly recommended for the hoses bigger than 125mm diameter. 

The irrigator has a differentiated poly pipe which has wall thickness getting less from the start to end. Therefore, the hose has the highest thicknes where the heaviest weight is and the lowest thickness where the lowest water pressure is. This special hose allows you to maintain the highest water pressure you have and run the machine efficiently.
