Lifting spreader beam calculation.

The difference lies in the way the forces are transmitted. Spreader bar lifting device calculations and design spreader bar lifting device calculations and design. Lifting factor f is the acceleration factor. How to design a spreader bar.

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. Find the load capacity minimum and maximum spread and headroom that fits your application. 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. 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.

So we must dismiss this mod. A lifting beam is a below the hook lifting device that performs the same function as a spreader. Lifting calculation method 3. 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.

Design of weld joint of the eye bracket with the spreader beam for shear strength 50 of the allowable stress is governing. Choose from modular adjustable and two position spreader beams and fixed and adjustable fiberglass battery lifting beams. 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. Dynamic factor when the movement of the precast unit is performed by lifting gear dynamic forces that depend on the lifting gear used appear.

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. Spreader beams are universally applied gear which is widely used in various types of lifting operations onshore and offshore. Safe working load swl. Sparta s approach to optimizing the spreader bar design otherwise known as lifting bar or lifting beam is an iterative process.

High quality spreader beams from grainger help lift uneven loads and keep them level for increased safety.
