Solution
The solution from Rutec Engineering provides two cable connections that serve as extendable and retractable telescopic elements. They are retracted with a winch and pull the construction upwards with the spray nozzles. The system is also lowered by rolling out the winch. The advantage of this mechanism is that no additional height is required above the spray boom. The arms simply "bend" from the vertical to the horizontal level. This design is made possible, among other things, by the particularly flexible
plastic energy chains. They reliably follow the lifting movements and safely guide all power cables and hoses. They also ensure cable guidance in particularly confined spaces in the installation.
