Lifting Lug Design Calculator
Een hijsoog (ook bekend als een nok of een pad-oog) is a device commonly found on a range of equipment and structures, including storage tanks, scheepscontainers, and other vessels that need to be lifted and moved around.
When analyzing and designing lifting lugs, various modes of failure must be checked. The SkyCiv Lifting Lug Snel ontwerp allows you to design lifting lugs of various dimensions and loading based on the following standards:
- AISC 360-16 Hijsoog ontwerp
- ALS 4100:2020 Hijsoog ontwerp
The lifting lug capacities calculated in this calculator include maximum tension capacity, maximale draagkracht, maximale afschuifcapaciteit, maximale pin-uitscheurcapaciteit, en lascapaciteit.
About the Lifting Lug Design Calculator
Wat is een hijsoog?
In its most basic form lifting lug is a metal plate with a hole in it attached to equipment like shipping containers, equipment skids, structural elements, various types of tanks, en meer.
Zoals de naam al doet vermoeden, lifting lugs enable things to be lifted and moved around on construction or other industrial sites. Daarom, they must be designed so that the hole is resistant to bearing and shear failure, and the welds are strong enough to resist stresses in the plate and neck of the lifting lug.
Lifting lugs are commonly made of carbon, structureel, or high-strength steel, depending on the exact nature of the lifting application. The plate can typically be as thin as 12mm (3/8in) for light loads and upwards of 50mm (2’’ inches) for heavy industrial loads. The hole diameter will also range based on the plate size and the size of the eyebolt used when lifting. Over het algemeen, the width and height of the lifting lug will be factors of the hole size, bijvoorbeeld, the width maybe 2-3 times the hole diameter and the height 3-4 times the hole diameter. Some examples of lifting lug diagrams can be seen below.
Design of Lifting Lugs
AISC 360 Lifting Lug Quick Design
De AISC 360 Quick Design Lifting Lug module completes the following design capacity checks:
- Maximale spanningscapaciteit
- Maximaal draagvermogen
- Maximale afschuifcapaciteit
- Maximale pinuitscheurcapaciteit
- zodat ingenieurs precies kunnen nagaan hoe deze berekeningen zijn gemaakt
Momenteel, the lifting lug calculation is based on the E49XX electrode. De AISC 360 Lifting Lug Quick Design supports only limited calculation of eccentric in-plane moments.
ALS 4100:2020 Hijsoog ontwerp
De AS 4100:2020 Quick Design Lifting Lug module completes the following design capacity checks:
- Tension in Lug
- Shear in Lug
- Bearing in Lug
- *Shear and Tension in Weld
Depending on the static lifting weight, lifting angle, and dynamic amplification factor, the net action of forces acting on the lug is calculated. The lug capacities are then worked out in tension (yielding), schuintrekken (horizontal and vertical), en lager.
The same are compared concerning the design action of forces, and the utilisation factors are evaluated against each mode of failure for tension, schuintrekken, en lager, and compared to the design action of forces. Weld capacity is also checked for Shear and Tension.
De AS 4100 Lifting Lug Quick Design can take the Dynamic Amplification Factor (DAF) as an input. This factor is to account for dynamic effects that often arise because structures respond differently to moving or changing loads compared to static loads. The DAF helps translate the impact of dynamic loads into a format that can be handled within the static load calculations by amplifying the load to reflect the increased stresses and strains on the lifting lug.
Houdt de rekenmachine rekening met hijshoeken??
Ja, the Quick Design Lifting Lug Calculator can consider the Maximum Angles of Load can be provided as an input, which will be used ultimately for checking the weld strength.
Accessing the AS 4100:2020 Ontwerpsoftware voor hijsogen
SkyCiv maakt ook het ontwerp van hijsogen mogelijk volgens de Australische standaard 4100. To access this version, please switch design codes using the flag icon at the top of the input panel. De AS 4100 Met de ontwerptool voor hijsogen kunt u de capaciteiten van een stalen hijsoog berekenen op basis van de lengte ervan, breedte & hoogte. De berekende capaciteiten zijn inclusief lagering, schuintrekken, buigen, en lascapaciteit.
Vrijwaring: Hijsoog ontwerp
De SkyCiv Lifting Lug Calculator-tool is alleen bedoeld voor het voorlopige ontwerp van hijsogen volgens AISC. Bij het ontwerpen van hijsogen, aanvullende factoren, zoals hechtingsstress, moet mogelijk worden overwogen om vervorming en integriteit van het vaartuig tijdens hijswerkzaamheden te voorkomen.
In scenario's waarin hechtingsstress aanzienlijk is, it is strongly advised that engineers consult additional sources beyond the initial lifting lug calculations provided by this tool. Verdere ontwerpcontroles zouden het uitvoeren van controles met goedmazige eindige-elementenanalyse moeten omvatten, het raadplegen van gekwalificeerde deskundige ingenieurs, en conform alle relevante lokale ontwerpcodes.
Lifting Lug Software FAQs
