发明名称 Equipment for use on covering a sports stadium
摘要 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.
