Experimental testing of sprint lift for liftingconcrete beams (English)
Abstract [sv]

Sprintlyftet är ett vanligt lyft som används på byggarbetsplatser idag för att montera betongbalkar och det används dessutom när betongbalkarna hanteras i fabriken där de tillverkats. Allt fler prefabricerade byggelement tillverkas och det leder till att lyftens kapacitet behöver säkerställas.

I den här studien provades kapaciteten experimentiellt i ett specifikt lyft, sprintlyftet. Det är ett lyft som Abetong använder till sina betongbalkar. Det som under studien kontrollerades var om betongbalkarna idag klarar mer än vad de gjorde vid motsvarande provning för 42 år sedan.

En jämförelse mellan provningar som gjordes av Abetong år 1975 och den här studiens provning visar att sprintlyften som används idag klarar av mer last än vad provningarna från 1975 gjorde. Förklaringen till det är främst att kvalitén av betongen har utvecklats under åren.

Abstract [en]

The sprint lift is a common lift used on construction sites today to mount concrete beams and it is also used when the concrete beams are handled in the factory where they were manufactured. More and more prefabricated building elements are manufactured and this means that the lifts capacity needs to be ensured.

In this study, capacity was experimentally tested in a specific lift, the sprint lift. It is a lift that Abetong uses for its concrete beams. What was checked during the study was if the concrete beams today manage more than they did in the corresponding test 42 years ago.

A comparison of tests made by Abetong in 1975 and this study's test show that the sprint lift used today is capable of more load than what the 1975 tests did. The explanation for this is primarily that the quality of the concrete has developed over the years.
