Abstract
Urządzenie do ograniczenia ruchu kabiny lub przeciwwagi dźwigu ciernego posiada dwa słupki (3 i 4) pionowe jednakowej długości przesuwne względem siebie w dwóch płaszczyznach. Słupek (3) zamocowany jest w przesuwnej prowadnicy (2), której ruch ogranicza podstawa (1). Słupek (4) przymocowany jest do przeciwwagi (10) w przypadku zabezpieczania górnej strefy bezpieczeństwa lub kabiny w przypadku zabezpieczania dolnej strefy bezpieczeństwa. Podczas normalnej pracy dźwigu słupki (3 i 4) mijają się ze sobą, a uzyskana strefa bezpieczeństwa podczas zadziałania urządzenia zwiększa się o długość jednego słupka. Podstawa (1) posiada dwa łączniki (5, i 7) bezpieczeństwa, które sygnalizują skrajne położenia słupka (3) i aktywują bądź deaktywują działanie systemu bezpieczeństwa dźwigu. Przesuwna prowadnica (2) jest chroniona przed dostawaniem się zanieczyszczeń pomiędzy prowadnicę (2) a podstawę (1) za pomocą osłony (6). Działanie słupka aktywuje się za pomocą ciągnięcia za linkę (8) lub (9) aż do powierzchni oporowej podstawy (1) i zadziałania łącznika (5 lub 7) bezpieczeństwa.The device for limiting the movement of the cabin or counterbalance of the friction crane has two vertical posts (3 and 4) of equal length sliding relative to each other in two planes. The post (3) is mounted in the sliding guide (2), whose movement is limited by the base (1). The post (4) is attached to the counterweight (10) when securing the upper safety zone or the cab when securing the lower safety zone. During normal operation of the crane, the posts (3 and 4) pass each other, and the obtained safety zone during the operation of the device increases by the length of one post. The base (1) has two safety connectors (5, and 7) that signal the extreme positions of the post (3) and activate or deactivate the operation of the crane safety system. The sliding guide (2) is protected against dirt between the guide (2) and the base (1) by means of a cover (6). The action of the post is activated by pulling the cable (8) or (9) up to the abutment surface of the base (1) and activation of the safety switch (5 or 7).
