A watering system for use in a greenhouse has a hose carrier that is supported entirely on a single track, the track having a rectangular cross-section. The hose carrier is connected by a cable that winds through a series of pulleys to a drive system so that the carrier moves at one-half the speed of the drive system as the drive system moves along the track in either direction. The water supply and electrical supply are connected at the approximate mid-point of the track and the hose carrier distributes the hose and electrical conductor among support brackets located along the track so that neither the hose nor the conductor become tangled. The tension on the hose and conductor is minimal as each support bracket has rollers thereon and the hose and/or conductor are not used to apply force to the hose carrier to move it along the track. The support brackets on one half of the track can be much smaller than the support brackets on the other half of the track as the hose carrier travels on one-half of the track only. Previous systems have used double tracks, which are more complex and more expensive. Also, it is much more difficult to move a watering system from one track to another track when the track is double than it is when the track is single.
Système d'arrosage pour serres, comportant un porte-boyau d'arrosage entièrement supporté par un rail unique de section rectangulaire. Le porte-boyau d'arrosage est relié par un câble à un système d'entraînement comportant une série de poulies servant à réduire de moitié la vitesse de déplacement du porte-boyau sur le rail de support dans l'une ou l'autre directions opposées. Les sources d'alimentation en eau et en électricité sont raccordées au voisinage d'un point situé au centre du rail de support; le boyau ainsi que les conducteurs d'énergie sont soutenus par des supports répartis le long du rail afin de prévenir tout risque d'enchevêtrement. La tension du boyau et des conducteurs est minimale, chaque support étant pourvu de galets, et ni le boyau ni les conducteurs n'étant utilisés aux fins de déplacement du porte-boyau. Des supports beaucoup plus petits peuvent être utilisés pour soutenir le boyau et les conducteurs le long d'une première moitié du rail, le porte-boyau d'arrosage ne se déplaçant que sur une moitié du rail. Les systèmes de versions antérieures ont fait appel à des rails doubles, plus complexes et plus coûteux. En outre, il est beaucoup plus difficile de déplacer le porte-boyau du système d'arrosage lorsque le rail est double.
