ABSTRACT:
A cable car type vehicle arrester features a pair of trumpet bars which are interconnected by a link which either maintains the distance between the bars constant or reduces same upon one of the bars being deflected outboard of its home or rest position. This reduces the free swinging time of the vehicle between bars and increases the distance through which the bars subsequent to the initial deflection are deflectable by the vehicle. This accordingly increases the stroke of shock absorbers associated with the bars increasing the conversion of the kinetic energy of the vehicle. Casters can be provided to support the bars to allow longer lighter bars with less robust bearing and structural members. The casters can be run on a corrugated surface to cam the bars vertically further increasing the kinetic energy conversion and endow a self-centering action on the arrester. Extensions on the trumpet bars which are coextensive with guide rails on the station are simultaneously engageable with a roller or rollers on the vehicle for forcing the trumpet bars back to a centered or home position.
