Spreader suspended by a sling often has the advantage over a lifting beam.
Spreader beam design example.
Below the hook lifting devices such as spreader bars and lifting beams must be designed in accordance with asme bth 1 and are to be manufactured and used in accordance with requirements of asme b30 20 which specifies requirements for marking inspection construction and operation.
It increases the a dimension and the forces in the beam are a combination of bending and.
There are a number of ways you can utilise our modular spreader beams for example.
In summary whenever the force must travel along the beam bending stress occurs and that is what we would call a lifting beam.
Design of adjustable spreader lifting beam of standard profile heb series geometry of lifting at the each end of the hollow pipe spreader beam solved using the equations of static equillibrium a strength design design for flexural bending stress selecting the section initially based on this.
This spreader beam also has a series of lugs on the bottom to attach to the product.
This example has an i beam down the center and a series of lugs welded on the top for attaching to the crane.
In this the beam is suspended from a sling connected part way along the beam rather than at the ends.
Need a span of 20m 66 but are only lifting 70t we can provide you with a mod 250 70 giving you cone adapters and.
The forces acting on the children and the swing in this example are very similar to what occurs in a spreader.
Design 1 typical spreader bar design.
Alternatively the combination design previously referred to can be used.
Asme b30 20 bth 1.
As some of you may have guessed in this example the broom is the spreader beam.
The typical approach to a spreader bar design looks like this.
Spreader beams are universally applied gear which is widely used in various types of lifting operations onshore and offshore.
In this article we will explore the design of a basic spreader beam and see what design checks are needed to establish the suitability of a spreader beam for particular lifting operation.
