Ladder mounting equipment in access to the roof of a container, in particular a stacked one

Osprzęt drabiny ma adaptery górny (A) i dolny (B) kotwione zamkami w usytuowanych ponad sobą górnym i dolnym narożniku kontenerowym za pośrednictwem rygli zaciskowych (3A, 22B). Rygle zaciskowe (3A, 22B) zamocowane są trwale do śrub sztywno połączonych na drugim końcu do elementów mocujących końce podłużnic (26.2) drabiny. Rygle (3A, 22B) po wsunięciu i przekręceniu w owalnych otworach bocznych zewnętrznych ścianek narożników kontenerowych zaciśnięte są na tych ściankach przez nakrętki, obracane kołem gniazdkowym (6) w adapterze górnym (A) i rękojeścią pokrętną (24) w adapterze dolnym (B). The ladder rig has an upper adapter (A) and a lower adapter (B) that are anchored with locks in an upper container corner and lower container corner situated vertically in relation to each other, by means of clamping pieces (3A, 22B). The clamping pieces (3A, 22B) are permanently fixed to bolts rigidly connected on the other end to elements that fix the ends of the rails (26.2) of the ladder. The clamping pieces (3A, 22B) - after being pushed in and turned in the oval openings of the side external walls of the container corners - are clamped on said walls with nuts, rotated with a sprocket wheel (6) in the upper adapter (A) and with a turn handle (24) in the lower adapter (B).In the second solution, the upper adapter (A) and the lower adapter (B) are anchored with locks (ZA, ZB) to an upper container corner (27) and a lower container corner (28) by means of clamping pieces (3A, 22B) that are permanently fixed to bolts (2A, 21B) rotationally connected on the other end to closed sections (36A, 36B) that have a quadrangular cross-section surrounding the rail of the single-rail ladder (32) with support rungs on both sides (33) in its upper and lower outermost segments. The bolts (2A, 21B) have axially-symmetrical spacer plates (25) and nuts (37) with turn handles (24), whereas the clamping pieces (3A, 22B) - after being pushed in and turned in the oval openings (29) of the side walls of the corners (27, 28) - are pressed against said walls by means of rubber caps (38) that adhere to the spacer plates' (25) surfaces.List of items marked in the drawingA.
