Spreader beams are universally applied gear which is widely used in various types of lifting operations onshore and offshore.
Spreader beam design calculation.
In this the beam is suspended from a sling connected part way along the beam rather than at the ends.
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.
Spreader suspended by a sling often has the advantage over a lifting beam.
It increases the a dimension and the forces in the beam are a combination of bending and.
How to design a spreader bar.
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.
Sparta s approach to optimizing the spreader bar design otherwise known as lifting bar or lifting beam is an iterative process.
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.
