It increases the a dimension and the forces in the beam are a combination of bending and.
Spreader beam design calculation.
Spreader beams are universally applied gear which is widely used in various types of lifting operations onshore and offshore.
In this the beam is suspended from a sling connected part way along the beam rather than at the ends.
Variations in the design of the multi lift spreader bar evolve over a period of time as requirements and technology change and the demand for a more efficient product is desired.
How to design a spreader bar.
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.
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.
This excel sheet helps the user check the strength and adequacy of a spreader beam used for lifting operations it calculates the design load the dynamic amplification factor daf and lifting point loads it also calculates sling loads and checks sling angles.
Alternatively the combination design previously referred to can be used.
