The aspects herein relate to the field of fall prevention systems, and more specifically to fall arrest systems for storage bins and more particularly to grain bins or silos. In one aspect, a fall prevention system for a ladder may have an anchor plate coupled to a roof. In another aspect, the fall prevention system for the ladder may have an anchor bar coupled to at least a portion of the ladder. A rope is coupled at one end to the anchor plate or bar and at the other end to at least one rung of the ladder using a fastener. A rope grab is slidably coupled to the rope between the anchor plate or bar and the fastener.

A portable storage bin includes a base frame on the ground and a bin support frame operable relative to the base frame between a working position and a transport position which is reduced in height relative to the working position, and a storage envelope supported on the bin support frame to define a storage chamber for storing particulate material therein in the working position of the bin support frame in which the storage envelope is collapsible with the bin support frame from the working position to the transport position. The bin support frame has an upper frame portion from which the storage envelope is suspended in the working position and a central support post which is extendable in height between the upper frame portion and the base frame for raising the envelope from the transport position to the working position.

The present invention relates to a ventilating and blanking device for a coal storage Eurosilo. The ventilating and blanking device includes a top blanking pipe, an axial flow fan and a baffle door, the top blanking pipe including a first pipeline and a second pipeline, an air supply pipe is connected to a side wall of the second pipeline, and the baffle door is connected to a driving mechanism; during blanking, the driving mechanism drives the baffle door so as to make the baffle door close the air supply pipe and the axial flow fan is shut off; and during ventilation, the driving mechanism drives the baffle door so as to make the baffle door close the first pipeline, and the axial flow fan is turned on. Compared with the prior art, the present invention has the advantages of ventilation efficiency, good ventilation effect, etc.

A flexible portable silo for storing grains and bulk materials, comprising a flexible cylindrical wall and a flexible conical roof made of a flexible, foldable, tension bearing sheet membrane, and a single pressure bearing post, with outriggers installed at the top of the post. The flexible cylindrical wall and conical roof are then draped over the outriggers and post and filled with grain or other bulk material.

A fan assembly attaches to and may be used with an existing fan of a storage container. The fan assembly includes an exhaust fan, a mounting assembly for operatively mounting the exhaust fan to the existing fan of the storage container, and a sealing member operatively positioned between the exhaust fan and the existing fan to provide a seal to direct movement of air streams created, in part, by the exhaust fan. During operation of the exhaust fan, the exhaust fan pulls contaminated air and airborne matter from within the storage container through the existing fan and an existing duct in order to exhaust the contaminated air and airborne matter from the storage container.

A collapsible storage system for flowable material, for example granular material, includes a base frame and an upper frame which is movable between a collapsed position and a working position spaced above the collapsed position. A plurality of storage silos are supported in a row, each including a hopper discharge cone on the base frame and a collapsible tubular wall assembly connected between the discharge cone and the upper frame. Redundant loading conveyors are provided in communication with the silos across the upper frame for loading and redundant unloading conveyors are provided in communication with the silos across the base frame.
