Abstract

The safety device for hand led motorized compacting rollers is designed to prevent injury to the operator when reversing and encountering an unobserved fixed obstruction i.e. to prevent crushing between the roller handle and the obstruction, and constitutes a buffer bar which yields under pressure to effect arrest of the motor drive. Pref. a mobile bar is mounted on the rear of the roller guiding handle bar and it connects via a transmission to the roller speed control. The transmission constitutes a primary jack actuated by the bar and a second jack acting on te speed control.
