ABSTRACT:
A vertically adjustable safety railing system for obtaining safety railing access to the tops of mobile equipment of various heights such as tank trucks. The safety railing apparatus generally includes a plurality of posts, a railing, and activating means in communication with an actuating means. The safety railing having a collapsed condition and a vertically upright condition. The posts are pivotally mounted to mounting plates as well as connected to the railing so that when the posts are rotated to a vertically upright condition, the railing is elevated providing a railing to assist a person walking on top of the tank of a truck. The activating means is engaged by a cover plate hinged to a ladder disposed at the rear of the tank truck. Opening the cover plate to access the ladder places the activating means in a passing condition and actuates the actuating means to pivot the railing system to its upright condition. Closing the cover plate places the activating means in its normally non-passing condition and returns the railing system to its collapsed condition.
