How do you calculate lifting lugs?
A lug, also known as a lifting lug or a padeye, is essentially a plate with a hole in it where the hole is sized to fit a clevis pin….The dimensions from the figure include:
- D = hole diameter.
- Dp = pin diameter.
- e = edge distance.
- a = distance from edge of hole to edge of lug = e − 0.5 D.
- w = width.
- t = thickness.
How much weight can a pad eye hold?

What are lifting lugs?
Small projections attached to, or built into, heavy components. The lugs have an opening in the center to which cables can be attached for lifting. Lifting lugs are in the construction of storage tanks and multi-grade dispensers.
What is a lifting eye?
Lifting eyes, also commonly known as eye bolts, have widespread use in industrial plants. They are commonly used on dies, cabinets, compressors, heat exchangers, motors, molds, and other equipment to facilitate their movement, either when being installed or moved to a different plant location.
How is lifting capacity calculated?
Measure geometric components
- The standard calculation for maximum crane capacity is (r)(hC)/100.
- R = Radius between the ground and load.
- hC = Lifting height multiplied by the capacity.
How much weight can a 3/8 eye lag hold?
In case you didn’t already know, an eye bolt’s “rated capacity” describes how heavy of a load a single eye bolt can support when the load is angled at 0 degrees through the eye bolt’s shank….How Much Weight Can An Eye Bolt Hold? [ANSWERED]
