A covering equipment for use on sports arenas for protection against precipitation is shown. The equipment comprises a driving motor (6, 9) and a longitudinal drum (14) for coiling and uncoiling a covering sheet, such as a tarpaulin or plastic coversheet. The casing (6) for the driving motor is arranged so as to rotate independently relative to the elongate drum (14), the motor drive shaft (9) is rigidly connected to the drum (14) for rotation therewith, and the motor casing (6) is fixedly connected to a reaction arm (2) which makes contact with the gound, so that during motor operation the casing (6) of the driving motor remains stationary with respect to rotation while the drum (14) is driven round.

L'invention a trait à un équipement de couverture utilisable dans des arènes sportives servant à assurer une protection contre les précipitations. Cet équipement est constitué d'un moteur d'entraînement (6, 9) ainsi que d'un tambour longitudinal (14) permettant d'enrouler et de dérouler une feuille de couverture, une bâche ou toile plastique protectrice, par exemple. Le coffrage (6) du moteur d'entraînement est conçu de manière à tourner de façon indépendante par rapport au tambour allongé (14). L'arbre d'entraînement (9) du moteur est relié de manière rigide au tambour (14) afin de tourner avec lui tandis que le coffrage du moteur est rattaché à demeure à une barre de réaction assurant le contact avec le terrain, de telle sorte que, lorsque le moteur fonctionne, le coffrage (6) du moteur d'entraînement demeure immobile alors que le tambour (14) tourne.
