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.
It can be used for an i beam spreader a hollow pipe spreader or a hollow rectangular beam.
Spreader beams for up to 400t are in stock and available worldwide for distribution please contact modulift for an immediate quote or further details.
How to design a spreader bar.
It calculates the compressive stress on the spreader beam and checks if the spreader beam is adequate.
It increases the a dimension and the forces in the beam are a combination of bending and.
It calculates the design load the dynamic amplification factor daf and lifting point loads.
Alternatively the combination design previously referred to can be used.
Every modulift modular spreader beam consists of a pair of end units and a pair of drop links with interchangeable struts that.
It also calculates sling loads and checks sling angles.
