Beschreibung
Zusammenfassung:	A movable machine includes a frame, an electrical motor on the fame, a cable electrically connected to the motor and adapted to be connected to a source of power, and a sheave bracket assembly coupled to the frame. The sheave bracket assembly includes two mounting plates, two spaced apart sheaves rotatably mounted on the mounting plates, a hinged portion coupled to the mounting plates and pivotally coupled to the frame, and at least one biasing member located between the frame and the mounting plates that biases the mounting plates and sheaves toward a first position. L'invention concerne une machine mobile qui comprend un châssis, un moteur électrique sur le châssis, un câble connecté électriquement au moteur et pouvant être connecté à une source d'alimentation, et un ensemble support de poulie couplé au châssis. L'ensemble support de poulie comprend deux plaques de montage, deux poulies espacées, montées de façon à pouvoir tourner sur les plaques de montage, une partie articulée couplée aux plaques de montage et couplée pivotante au châssis, et au moins un élément de sollicitation situé entre le châssis et les plaques de montage, ledit élément sollicitant les plaques de montage et les poulies vers une première position.
