UNDER-GROUND RAISE, MANHOLE, VAULT, OR MAN-WAY SAFE ENTRY/EXIT SYSTEM

摘要

A safety system, attached to the underside of a access (lid, cover, grill, grate, or hatch), that allows the user to mount and dismount a ladder below in an ergonomically friendly and safe manner. The safety system comprises of a locking device (post member) and two handrails attached to the underside of the access cover. This locking device (post member) has a weighted latch on top that holds it in a stored un-operational position until needed. The handrails are attached in line with the manhole ladder handrails. When the access cover is in a vertical open position the locking device (post member) can slide down into a stationary hollow receiver sleeve that is in a permanent fixed position below the surface of the access cover. This secures the access cover in a vertical open position, allowing the user to utilize the handrails on the underside of the access cover as an extension of the ladder that is affixed below the surface of the access cover.
