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.
Lifting spreader beam calculation.
We verify by the formula of question 3 that for the 20º configuration we require a height of 1 37x that is 27 4 meters of height which exceeds the predetermined height requirement in this example case.
The lifting classes are described in din 15018.
It consists of a body and a set of lugs just like a spreader bar but lifting beams generally have one lug on the top in the center and 2 or more lugs along the bottom.
The difference lies in the way the forces are transmitted.
Lifting beam v lifting spreader lifting beams lifting frames and lifting spreaders are a means of providing two or more lifting points from the hook of the lifting machine or crane spaced so as to match the position of the lifting points on the load.
Choose from modular adjustable and two position spreader beams and fixed and adjustable fiberglass battery lifting beams.
Spreader beams are universally applied gear which is widely used in various types of lifting operations onshore and offshore.
When lifting and carrying precast elements the lifting load has to be.
Safe working load swl.
We check the capacity of a spreader beam sb 170 that supports up to 170 tons and check that it reaches that capacity at 20m but only at 20º.
Dynamic factor when the movement of the precast unit is performed by lifting gear dynamic forces that depend on the lifting gear used appear.
A lifting beam is a below the hook lifting device that performs the same function as a spreader.
So we must dismiss this mod.
High quality spreader beams from grainger help lift uneven loads and keep them level for increased safety.
Lifting factor f is the acceleration factor.

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.
Spreader bar lifting device calculations and design spreader bar lifting device calculations and design.
Find the load capacity minimum and maximum spread and headroom that fits your application.
