ENERGY EFFICIENCY WITH LOW ENERGY CONSUMPTION, THANKS TO RM TURBINE GEAR BOX REDUCTION
RM Irrigation Turbine .png

The energy required to rewind the hose is the decisive element in the economy of the self-propelled irrigation machines: RM Turbo-Reducer Unit with in-built water By-Pass and four-speed gearbox drastically reduces pressure losses during the irrigation phase, thus ensuring money saving determined by less energy consumption.

      

The design of the turbine impeller is the result of a cutting edge aerodynamic calculation which allowed reaching an extraordinary channelled flow of the liquid without any turbulence, thus ensuring the operation with a minimum pressure of 1.5 bar at machine inlet. The quality of the Turbo-Reducer Unit is obtained by using all the movable internal parts in stainless steel, such as all bearings (including the ones of the turbine axle) in class A dipped in oil bath.

The system includes a built-in automatic brake that engages during hose unwinding and disengages during rewinding. Moreover, at the end of rewind the Turbo-Reducer positions the “Operation-Stop” lever to the correct position for the following hose unwind.

The exclusive RM Power Save™ system allows for a practical, quick speed change even during the normal hose rewind with water under pressure, thus immediately reducing the turbine rotational speed without having to act on the electronic programmer controls.

RM Turbo-Reducer Unit does not require any periodic maintenance. Moreover, at the end of sprinkling process every liquid residue is automatically ejected from the turbine body.

High Quality Chain Means High Accuracy Driven Rates Of The Reel

Another remarkable characteristic of RM hose-reel irrigation machines: starting from the 581 Gx Evo model the drive between turbo-reducer and reel is manufactured with high-tensile strength ARNOLD STOLZEMBERG® chain with extruded rollers and without extension.

Moreover, by using the adjustable toothing (another exclusive of RM) located in the outer reel diameter, a very high transmission gear ratio is created between the wheel and turbo-reduction gear in order to drastically reduce the energy absorption for rewind as well as the turning moment in the reduction gear output shaft, thus preserving its duration in time.

REEL AXLE: THE BEST TECHNOLOGY AVAILABLE IN THE MARKET

Reel mass with its hose in polyethylene wound and filled with water reaches 80% of machine weight. 

Supports on which reel rotates are subject to very high loads, thus generating high frictions, which must be minimized in order to reduce the effort required for the movement.                 

Already starting from the 540 Gx model RM reel axle is: 

  1. Supported by large diameter rolling-element bearings that cancel frictions (1);   

  2. Protected by an interchangeable stainless steel compass (2) on which lip seals operate, thus ensuring that it lasts long even in the presence of aggressive fluids such as sludge. 

  3. Aided maintenance: when lip seals are worn out, they can be replaced in a few minutes.

This technology – an exclusive of all RM models – is applied to the whole range, including the cheapest models.

INTUITIVE OPERATION BY MEANS OF RM RAINMASTER 2.6 PROGRAMMERS

RM electronic programmers were designed to be perfectly built into the irrigation machine. 

They are simply to use and feature an intuitive, multilingual display; it can be easily bypassed without interrupting the machine irrigation cycle in order to switch from automatic to manual operation.  

             

Electromechanical drain and/or shut-off valves, GSM modem, solar panel for battery and anemometer recharge are available as optionals. The optional additional gun of rewind end can be controlled as well.

MULTI-SECTION TECHNOLOGY FOR AN INDESTRUCTIBLE REEL STRUCTURE

Starting from the 581Gx model the reel resorts to the multi-section ribbed technology fitted with sides completely made up of high strength DOMEX 420™ sheet with yield load to 420 kg/mm2, made up of wedges precut by means of HD Laser system and then assembled through robotic welding. This leads to a high resistance to bending stress, despite the reel lightness, and to an increase by 300% of the PE hose supporting surface on reel sides - a remarkable advantage compared to the outdated system of side tubular tires. The internal ferrule is made up of calendered flat sheet, which helps preserve, then extend the duration of the polyethylene hose in the course of time.

The 890 Gx , 990 Gx  models feature the “tapering profile” side reel section, so that all side bends can be effectively counteracted even during the most difficult rewinds. 

Sections of each side were designed to be fully and thoroughly coated by the double-layer painting treatment even in the most internal parts. In that way steel does not deteriorate in the boxed or hidden parts. A side white segment allows checking the regular reel rotation even from a great distance.

HIGHER RESISTANCE TO AGING THANKS TO RM PAINTING CYCLE

A preventive pickling treatment is performed on the painted parts of all RM machines as well as a following painting process through a double-layer electrostatic system – which ensures a coating even in the most hidden machine parts – with highly eco-friendly water-based paints and primer. Each cycle is accompanied by an in-oven stabilization treatment at 60°C, thus obtaining surfaces which are highly resistant to corrosion and especially to UV rays.

MAXIMUM STABILITY AND DIRECTIONALITY UNDER ANY CONDITION, BY MEANS OF RM RAIN GUN TROLLEYS

All the trolleys are available in the two- or four- fixed tyred wheel version and a steering pneumatics. This wheel allows the trolley to follow the irrigation hose in the position where it was unwound (fig. A), as being steering it is steered by the PE hose itself, thus eliminating the typical inaccuracy of the fixed middle wheel or slide trolleys that are not included in the ideal trajectory during the paths not perfectly straight (fig. B).

   

Cast iron wheels with directional crests – expressly designed to be paired with the steering wheel – are supplied as optional. They increase the steerage and mass in the point where they are most required. Both wheels are fitted with hubs with tapering bearings and lubricator. 

The whole trolley structure is hot-dipped galvanized, thus ensuring an outstanding lifespan against corrosion.
