Boom Suspension
Why is boom ride and stability so important?
A boom which bounces, sways or yaws deposits chemical unevenly on the target. This can result in weed escapes and may even contribute to resistant weeds.
The Goldacres TriTech suspension system has been developed to provide you with the best boom ride possible and assist in an accurate application. Working in conjunction with the chassis airbags the boom features three-way suspension that works to reduce boom pitch, roll, and yaw – the three enemies of accurate application. A combination of springs and shock absorbers, as well as hydraulic cylinders and accumulators all work together to provide the best boom ride possible. The TriTech suspension system has contributed to Goldacres consistently having the best boom ride when measured against competitor machines.
Hydraulic yaw
1. Two opposing hydraulic cylinders are mechanically connected together either side of the pivoting boom centre section. As the centre yaws, one cylinder is retracted, the other is extended. This results in oil movement which compresses in a nitrogen-charged accumulator. The result is precise boom yaw control.
Roll
2. Delta links – The key to the superior boom ride is the strategically placed delta links. In all, there are four links. Each link features spherical ball ends which allow the centre to move in all directions.
3. Roll centre point – The roll centre point is the location at which the boom pivots around, both in roll & yaw.
4. Roll dampeners – Reduces high-frequency oscillation of the boom roll.
Parallelogram
The boom parallelogram lift provides 1200mm of boom height adjustment as well as the vertical boom suspension. The system is constructed of three heavy walled torque tubes and diagonal bracing to ensure less flexing which increases boom roll and yaw stability.
3D Breakaway
The end breakaway section protects the boom from stress damage if a ground, fence or tree strike occurs. The end section can break forwards, backwards and upwards. The spring mechanism uses an eccentric mounted sprocket and chain to provide maximum breakout force in the neutral position, then reduces the force the further the breakout.
