Lifeline retrieval device |
摘要 |
A self contained portable device for use on the roof of a building for retrieving a lifeline from along the side of the building. A motor and drum drive assembly is mounted on a movable cart. An adjustable davit arm is pivotally mounted on the cart and is adapted to extend over the edge of the roof. The lifeline extends around a sheave mounted on the outer end of the davit arm and through a rope grab clamp and then about the take-up drum of the drive assembly. The davit arm is formed by telescopically joined tubular arm sections. The motor is controlled by a foot operated switch for rotating the drum to retrieve the lifeline. A safety line is adapted to secure the cart to rigid structure on the roof in addition to a wheel brake.
