RAILROAD CAR DERAIL SENSING DEVICE AND RAILROAD CAR

摘要

A derail sensing device (1) is disposed upon the fore end part of a platform car (4). This device (1) comprises a mobile member (11), a sensing arm (12) as a derail sensing member, and a derail sensing line (3). The mobile member (11) moves in a prescribed direction by an action of a load which is greater than or equal to a prescribed value. When the sensing arm (12) receives the load which is greater than or equal to the prescribed value by contact of the platform car (4) with a rail line in a derailment, the mobile member (11) to which the load is transmitted moves in a prescribed direction. The derail sensing line (3) is configured such that, when the platform car (4) derails, either an electrical continuity state or an optical continuity state is blocked by the movement of the mobile member (11).
