This invention relates to a ground actuated lid operating system including (1) a pressure release lid apparatus operable to selectively open and close a pressure lid member to release fluid pressure from the interior of a silo structure; and (2) an entrance lid closure apparatus operable to open and close a closure lid member without leaving the area of the support surface adjacent the silo structure. The pressure release lid apparatus has the pressure lid member biased to a closed positive seal condition and opened through the use of a lid actuator assembly and lid linkage assembly which is operable from a position adjacent to a side wall of the silo structure not requiring the climbing thereof. The entrance lid closure apparatus is provided with an axially movable closure lid member which is movable from the open condition to add granular materials to the silo structure and laterally and subsequently downwardly to a positive sealed position about a silo entrance opening. The pressure release lid apparatus and the entrance lid closure apparatus are operable from a ground surface adjacent to a silo structure not requiring the climbing thereof which is a time, labor, saving function plus providing safety features.

A ground actuated lid operating system connected to a upright silo structure operable to be connected to access openings thereto, comprising: (a) a pressure release lid apparatus including a lid actuator assembly secured to a side wall of the silo structure; a pressure lid assembly secured to an upper portion of the silo structure; and a lid linkage assembly connected to the silo structure and operably connected to the pressure lid assembly; (b) said lid actuator assembly includes a lock handle assembly connected to a cable connector assembly and to a cable member to open and close a portion of said pressure lid assembly; and (c) said pressure lid assembly including a pressure lid member mounted about one of the access openings into the silo structure and having a lid biasing member to bias said pressure lid member to a closed condition; whereby said lid actuator assembly is operable through said cable member to open and close said pressure lid member to allow pressure within the silo structure to escape therefrom and being biased into a closed condition by said lid biasing member.
