Hatchway safety grab post safety barrier and grate |
摘要 |
A lift-up safety grab post mechanism for rooftop hatchway curbs having a mounting bracket on a hatchway curb and having an elongate opening having a pivot bolt for upward and downward grab post movement. A lift-up grab post has a pivot opening receiving the pivot bolt and having a stop member fixed thereto. The lift-up grab post is rotationally moveable between an upstanding position and a horizontal position relative to the roof hatchway curb. The mounting bracket defines a receiver seat and further defines a stop shoulder adjacent the receiver seat that prevents rotational movement of the grab post until the grab post has been raised from said receiver seat to a position above the stop shoulder.
