Abstract

Uppfinningen avser en vakuumtublyftanordning innefattande en lyftslang. (105), vilken lyftslang (105) uppvisar en första ände (106) för infästning av lyftslangen (105) och en andra ände (107) för anslutning till ett medel för sammankoppling av lyftslangen (105) med en last, varvid lyftslangen (105) är anpassad för anslutning till en vakuumkälla (101) och är ut- och hopdragbar för att genom reglering av trycket inuti lyftslangen (105) åstadkomma en utdragande eller hopdragande förflyttningsrörelse hos lyftslangen (105) för förflyttning av en last. En accelerometer (120) är anordnad i anslutning till lyftslangens (105) andra ände (107) för kontinuerlig övervakning av acceleration i minst en riktning vid lyftslangens (105) andra ände (107), i syfte att detektera en acceleration indikerande tappad last och en styrbar säkerhetsventil (130) är anordnad att reducera undertrycket i lyftslangens inre volym till en nivå som åtminstone sänker accelerationen vid indikering av tappad last.(Fig-1)
