This system works with 3 pipes, where the center pipe acts as a coil tubing and the system can be adjusted up to a height of 450 cm. With these large wind surfaces, there is a great advantage of the central pipe that strengthens the system.
In this version you can also control the system either with a hand crank or gear motor, and you must reset 250 cm space for the telescope cardan and gear motor.
By exceeding max. Instead, use a center-mounted gear motor with telescope cardan to both sides.
In this case, you must reserve 450 cm for the electrical system.
