Booms in an aircraft wing design

Both superbly robust and superbly light

Thanks to the special profile design AMAZONE booms are at the same time superbly light and superbly strong. The boom working widths from 21 to 42 m allow optimum adaptation of the sprayer to the structure of the farm. The exceptional high quality ensures a long operational life even over very high acreages. Compact transport dimensions with transport widths from 2.55 m contribute to safe road transport.

Maintenance-free and with a long service life

The decades of experience in boom design pay off: The conical hinge pin is the intelligent centre of a well thought-out boom philosophy! The boom pivots self-adjust against any play on the conical hinge pins and that ensures, for the end user, an optimised boom function even after many years.

The standard use of stainless steel, the automotive-industry standard, cathodic dip painting process and the targeted use of plastics and aluminium are the perfect guarantee of a long service life.

Super-L2 boom in working widths from 21 to 40 metres

Even with the maximum boom width of 40 m, the transport width of the Super-L2 boom is only 2.55 m. In the transport position, the boom is behind the cab. This means: no limitations in the field of vision for the driver and no liquid dripping in and around the cab area.

“The booms can be folded in either side independently or both sides together. This means that a variety of tramline widths can be covered making it the ideal solution for contractors”
(dlz magazine "Test report Pantera 4502" 2/2016)

Super-L3 boom in working widths from 36 to 42 metres

AMAZONE designed the Super-L3 boom for the most extreme of demands and it offers an absolutely smooth boom ride. Alongside the 36 m boom, a 42 m version is now also available which has an additional boom section on either side. The boom can be used at a reduced working width with pivot points at 12, 24 and 33 m.

On the basis of the 42 m boom, smaller working widths such as 40 m or 39 m can also be implemented by means of a shortened end section. Furthermore, a reduction joint can also be fitted to the outer boom section. This can be used to manually reduce the working width e.g. from 42 m to 39 m.

Super-L3 booms from a working width of 39 m are equipped as standard with ContourControl active boom guidance, SwingStop boom tip swing compensation and AmaSwitch or AmaSelect individual nozzle control with DUS pro in each case. 

The substantial boom sections with hydraulically pressurised break back joints in the boom ends ensure an absolutely smooth boom ride under any conditions. If any vibrations caused by cornering or acceleration occur in spite of the substantial design, they are directly reduced by SwingStop.

Flex-fold for Super-L2 and Super-L3 booms
AMAZONE offers two electro-hydraulically actuated boom fold options, Flex-fold 1 and Flex-fold 2. Each boom folding joint is equipped with an electro-hydraulic valve block that is directly controlled by the machine software. This enables faster folding. As soon as the first boom section is folded in or out by approximately 70%, the next section automatically starts to fold in or out.

Flex-fold 1
In addition to the benefits already outlined, Flex-fold 1 provides the following extra functions:

  • Height adjustment 
  • Folding in and out 
  • One-sided independent fold at reduced speeds (max. 6 km/h) 
  • Boom width reduction 
  • Tilt adjustment

Flex-fold 2
In addition to the advantages mentioned previously, Flex-fold 2 offers the following functions:

  • One-sided/bilateral positive boom angling 
  • One-sided/bilateral negative boom angling (in combination with ContourControl)

"To speed up the folding procedure, AMAZONE has replaced the simple sequence control by a sensor controlled process. With this we clocked a quick 19 seconds for folding out and 27 seconds for folding in – great!” (”profi“ – Test report Amazone UX 5201 Super - 10/2017)

Individual user profiles for reduced working widths

Via the user profiles in the machine software, individual profiles that recognise a reduced working width can be stored. If e.g. it is intended to fold out a 36/30/24 m boom to just 30 m, this can be carried out quickly and simply via a profile change. After folding out, the active working width is automatically detected and the outer nozzles are deactivated via the AmaSwitch or AmaSelect individual nozzle control. The reduced working width is automatically stored for Section Control.

Boom guidance with maximum comfort and even more precision

AutoLift – the comfortable automatic headland system
AutoLift automatic boom lift (standard equipment) lifts the boom to a pre-selected height every time the machine is switched off. 
It lowers back down again to the target height when the sprayer sections are switched on. This reduces the risk of damage to the boom while turning on the headland.

DistanceControl or ContourControl? Decide for yourself!
The DistanceControl and ContourControl automatic boom guidance systems offered by AMAZONE provide a suitable solution for every demand. The fully automated DistanceControl boom guidance leaves the control of your sprayer boom in the hands of the machine.

The innovative ContourControl boom control is AMAZONE’s high-end solution, ideal for customers with difficult terrain conditions. ContourControl provides maximum precision, even at high forward speeds.

  • Automatic boom pre-lowering in GPS-Switch 
    The GPS-Switch function in the operator terminal can be used to start lowering the boom before it reaches the untreated area. This means that the boom is already at the correct working height when the nozzles come on. Requirements for this function are just a field boundary saved within the GPS-Switch in the AMAZONE ISOBUS terminal.

DistanceControl with 2 sensors or DistanceControl plus with 4 sensors

As an option on the Super-L boom, AMAZONE offers the DistanceControl fully automated boom guidance system with 2 sensors or DistanceControl plus with 4 sensors for the Pantera self-propelled sprayer. DistanceControl with 4 sensors is recommended if the crop height varies greatly or there are areas with partially lodged corn. The sensors are electrically connected in parallel and so it is always the sensor that is closest to the target surface that is sensing.

Benefits of the DistanceControl boom guidance 

  • Fully automatic boom guidance including boom height, tilt adjustment and boom lifting on the headland  
  • Automated simultaneous boom angling, in combination with Flex-fold 2

  1. Ultra-sound sensors
  2. Angle sensors

ContourControl – reduces those vertical boom movements

With the active boom guidance system, ContourControl, AMAZONE offers a fully automatic boom guidance system for booms from 21 m working width. This meets the increasing demand for higher precision during application owing to the minimal deviations in the distance from the target surface, even at high forward speeds and large working widths. ContourControl can be used with Super-L booms in conjunction with either Flex-fold 1 or Flex-fold 2.

The basis of the new boom guidance system is a highly responsive electro-hydraulic system and 4 sensors, or as many as 6 sensors in combination with Flex-fold 2, which enable both automatic positive and negative angling.

The benefits of ContourControl: 

  • Optimum lateral distribution 
  • Precise, super-fast automatic height guidance 
  • Target surface distance below 50 cm – less drift 
  • Very quick folding processes 
  • Higher accuracy at faster working speeds 
  • Elegant boom control for those wider working widths

  1. One-sided positive angling on the right (Flex-fold 2)
  2. Simultaneous positive angling (Flex-fold 2)
  3. Simultaneous negative angling (Flex-fold 2)

SwingStop – for reducing the horizontal boom movement

In order to tailor the horizontal boom ride to the growing demands, e.g. wider working widths and higher forward speeds, AMAZONE offers SwingStop active boom tip movement prevention as an option for the ContourControl boom guidance system. By external influences, such as ground undulations, driving round bends, acceleration and deceleration and increasing operating speeds the boom is under extraordinary strain in the horizontal plane. This may result in the boom ends swinging back and forth and thus negatively affecting the lateral distribution at the outer ends of the booms.

Since horizontal movement occurs more at the boom ends, this effect is amplified by large boom widths. To reduce this horizontal tip swing effect, SwingStop measures, via acceleration sensors, the resulting acceleration at the boom ends. The two actively-operating hydraulic rams in the boom suspension compensate live for these swing movements and in this way provide a very smooth horizontal boom ride.

The benefits of SwingStop: 

  • Optimum longitudinal distribution 
  • Reduction of the horizontal boom movement for a very smooth boom ride 
  • A system which operates very quickly and precisely, even at high working speeds 
  • Highest performance and outstanding precision

  1. 6 ultrasound sensors for ContourControl
  2. Direction of travel
  3. 2 acceleration sensors for SwingStop
