Evolution Vario
The Evolution Vario is a dribble bar with a continuously variable working width between 21 and 36 m. It telescopes by up to 7.5 m on each side, so the driver adjusts the width from the cab while spreading. Hydraulically pre-tensioned steel cables, damped by a nitrogen bladder, keep the wide boom stable under braking.

The Evolution Vario in action!
A hydraulically pre-tensioned double steel cable system stabilises the forward-flying wings during braking, damped by a nitrogen bladder.

A height control sensor controls both arms separately, so the distance to the ground stays optimal across the full width.
Everything you need to know about the Evolution Vario
The Evolution Vario is a dribble bar with a maximum working width of 36 metres that can be telescoped by up to 7.5 metres on each side. This allows the driver to adjust the working width continuously between 21 and 36 metres, and offers the option of retracting one arm by 1.5 or 2 metres for buffer strips.
Bomech has used the experience gained from the wide trailing shoe systems and developed a damping steel cable construction at the top behind and in front of the dribble bar. When the driver brakes, the forward-flying wings are stabilised by the hydraulically pre-tensioned cables, which are damped by means of a nitrogen bladder.
Working widths of 36, 33, 30, 27, 24 and 21 metres are set by means of a cam track. Further features:
For extra flexibility and demanding conditions, the applicator offers the following:
- Any intermediate working width possible, per full metre, on request.
- Hydraulically pre-tensioned steel cable system for extra stability.
- Automatic height control with a sensor for both arms separately.
- From an active working width of 24 m, both main booms have a 3 m collision protection system.
- Drop-stop for road travel.
- Transport width 2.99 m for a maximum tank diameter of 2.1 m, mounting on wider tanks is possible.

How does the telescoping work?
The boom telescopes in by up to 7.5 m on each side. While it does, hose after hose is swivelled upwards by a cam track and folds in the middle area, so the hoses stay tight. That cam track also fixes the available widths: 36, 33, 30, 27, 24 and 21 m, in steps of 3 m.
Which working widths can I set?
36, 33, 30, 27, 24 and 21 m by means of the cam track, and any intermediate working width per full metre is possible on request. One arm can also be retracted by 1.5 or 2 m, for buffer strips along a ditch for example.
What keeps the boom stable at 36 m?
At 36 m the wings fly forward when the driver brakes. The hydraulically pre-tensioned cables stabilise them, damped by a nitrogen bladder, which keeps the boom under control and reduces the load on the frame.
How is the height kept right across 36 metres?
A height control sensor controls both arms separately, so each side keeps its own optimal distance to the ground. Without that, one arm would run too high or too low on any field that is not perfectly flat.
Is the machine protected against collisions?
From an active working width of 24 m, both main booms are equipped with a 3 m collision protection system. For road travel the drop-stop keeps the hoses secured.
What does the machine need from the tanker?
The 2.99 m transport width applies to a maximum tank diameter of 2.1 m, and mounting on wider tanks is possible. At 7,000 kg and 144 outlets this is a machine for large tankers and high capacities.
