THIS CONDUCTION SYSTEM IS NOT VERY COMMON IN THE WORLD BUT YOU MAY FIND IT IN SOME GERMAN VINE-GROWING REGIONS, USALLY IN VINEYARDS LOCATED ON STEEP SLOPES. THERE IS NOT A CONTINOUS WIRE SYSTEM, SO IT HELPS TO MOVE BETWEEN VINES WHILE WORKING.

THE TRUNK IS LEFT AT A HEIGHT OF 1.5 METRES AND IT ENDS IN A HORIZONTAL RING WITH 3 OR 4 METAL SPOKES. THE CANES ARE DISTRIBUTED AROUND THE RING. THIS PREVENTS THE BRANCHES AND BUNCHES FROM BEING LUMPED TOGETHER.

THE LEAVES AND BRANCHES WILL FALL DOWN FROM THE RINGS AS A CURTAIN, SO THE BUNCHES WILL BE ON THE TOP, WITH ENOUGH AIR AND LIGHT.
