DISPOSITIF ANTI-PIÈGE, DESTINÉ À DES TABLES ÉLÉVATRICES À CISEAUX

摘要

The present invention provides an anti-entrapment device (40) for an aerial lift (10) having a basket or cage (20). The anti-entrapment device (40) comprises an elongate housing (41); two or more sensors (42) housed within said elongate housing (41) and a switch activation device (43) coupled to the elongate housing (41). At least one of said two or more sensors (42) is positioned proximate an end of said elongate housing (41). Said switch activation device (43) is arranged at an angle to the orientation of said sensor(s) (42) positioned proximate the end of said elongate housing (41). The sensors (42) are arranged to provide a detection zone (48) and to detect obstacles within the detection zone (48). The sensors (42) are configured to facilitate the alerting of an operator standing in a basket or cage (30) to the presence of an obstacle that may potentially strike the operator before the strike occurs, and the switch activation device (43) is configured to prevent further movement of the basket or cage (20) once the switch activation device (43) is activated.
