Lifting-points are a connection between load and lifting-equipment and are required, for example, when working with lifting-chains, lifting-ropes or textile slings, such as lifting-slings, when loads need to be lifted or moved. Lifting-point is the generic term, whereby lifting-swivels and eyebolts are sub-categorized. The pre-selection for your lifting-point is usually the question of whether it is welded or screwed in, whereby we can supply you with the right lifting-points for both types of connection. A further subdivision is the rigid, rotatable or swiveling application, whereby Dolezych can also guarantee all applications with different products. At Dolezych, you can purchase various lifting-points such as eyebolts, lifting-brackets, lifting-swivels, stainless steel lifting-points, ring-brackets and welding-points and welding- and mounting-hooks based on your requirements.

Find the right lifting-point for your load
We help you to find the optimum lifting-point for your requirements.
Screwable and weldable lifting-points
The screwable or weldable lifting-points can be mounted as required and removed with little effort (e.g. if no longer required or disruptive in the subsequent work process). Thanks to the wide variety of threads, they can be attached to almost any load and are flexible in use.
- Usually already included in the design (e.g. trusses)
- Permanently connected to the load
- No additional threads required on the load
- No need to unscrew the lifting-point during use
Type of application: Swivel or rigid lifting-points
Rigid lifting-points:
- Rigid lifting-points include eyebolts or weldable eyebolts
- As the direction of pull cannot be changed, they are often used for single-leg solutions
- Used when load is only guaranteed in the prescribed tensile direction
Swivel or swivel and pivot lifting-points:
- These lifting-points are mainly used when using multi-leg slings, but are also used with single-leg solutions, for example, if the load needs to be rotated and positioned. (Note that this only applies to lifting-points that can be rotated under the load (e.g. Twister with ball bearings)).
- Rotating/folding lifting-points are more flexible than rigid lifting-points
- The direction of pull can be changed before or during attachment (please note the technical features)
Rotatable:
- Rotatable in the axis of the screwing direction
Rotatable and pivotable:
- Rotatable in the axis of the screwing direction
- Additional bracket for the swivel range
Can be rotated loaded or unloaded:
Adjustable in load direction:
- Before lifting (unloaded)
Can be rotated under load:
- During or before the lifting process (loaded or unloaded)
- Automatically aligns itself under the load in the load direction
- Actually only decisive for 1-leg solutions
- Continuous rotation is always prohibited
You should consider these selection parameters
- Total weight of the load
- Working area (swivel range, collisions)
- Number of lifting-points/strands
- Weldable or thread type and length
- Symmetry of the lifting-points (where is the load's center of gravity?)
- Angle of inclination of the lifting gear used
- Load direction of the lifting-points (fixed/rotatable, lateral attachment, etc.)
- Temperature influences
In addition:
- For sensitive surfaces, choose a lifting-point that ensures sufficient distance from the load and does not damage it
- Various systems offer lower installation heights, this can be an advantage or disadvantage for you, but must always be taken into account
Load capacities of lifting-points: What you need to consider
Shallow or steep angle? The load-bearing capacity of your lifting-point depends on the angle at which your load is attached.
- Flat angle: 45-60°
- Steep angle: 0-45°
The load capacities only apply...
...with symmetrical load distribution. Load capacities for asymmetrical load distribution can be found in the operating instructions.
...if the eyebolt rests flat on the entire bearing surface.
...if the forces introduced can be absorbed by the base material without deformations affecting safety.
Can you use lifting-points for lashing when securing loads?
If you want to use a lifting-point as part of your load securing when lashing, the permissible tensile force (LC) = 2 x WLL (load capacity). A lifting-point loaded with more than 1 x WLL during lashing may no longer be used for lifting!
