What is the role of strength calculation in the safety of lifting accessories?
Strength calculation is a critical part of the design and use of lifting accessories, as it ensures structural strength and safety. When lifting accessories such as lifting chains, hooks or slings are subjected to daily use, they must be able to safely withstand enormous loads. This requires their structural integrity to be carefully calculated and optimised.
At Hefmec, we always aim to give our customers a sense of security when we take on a project. Strength calculations allow us to assess the ability of materials and structures to withstand a range of forces and stresses, ensuring safety at every stage of the work. In this way, we can prevent accidents and extend the life of equipment, saving costs and increasing efficiency.
How is the strength calculation carried out in practice?
The implementation of a strength calculation is a multi-step process that starts with understanding the root cause of the problem. This step is critical, as obtaining the right initial data is key to ensuring the accuracy of strength calculations. The first step is to select materials and accurately determine their properties, followed by a detailed structural analysis.
At Hefmec, we use both linear and non-linear analysis to accurately model the behaviour of structures under different loads. Linear analysis is well suited to simpler structures and loads, while non-linear analysis is essential for more complex structures and loads.
The analyses are followed by a review of the results and a suggestion for possible improvements. This step is important to ensure that each component designed meets or exceeds the required safety standards. In this way, we ensure that our customers can have confidence in the safety and durability of their lifting equipment.
What tools and software are used for strength calculations?
Modern strength calculations make use of a number of advanced tools and software that improve the accuracy and efficiency of the calculation. At Hefmec, we use advanced FEM (Finite Element Method) software that enables accurate analysis of complex structures. This software allows us to simulate and evaluate the behaviour of structures under different loading conditions.
We also use various material databases and simulation software to help us choose the right materials and design structures optimally. These tools allow us to provide our customers with accurate and reliable solutions that improve product safety and reduce the risk of design errors.
Examples of applications of strength calculations
At Hefmec, we have carried out strength calculations on a wide range of projects covering a broad spectrum of industrial needs. One example is the strength calculation of load-bearing steel structures, where we ensure that the structures can withstand the designed loads without damage. Another example is the strength calculation of ball valve lifting and pivoting accessories, where we check that the accessories can safely withstand the required forces.
We have also carried out strength calculations for the supports of wind turbine maintenance facilities, ensuring their safety and durability in harsh weather conditions. Such projects show how strength calculations can support innovative solutions and efficiency in industrial production.
Hefmec is committed to providing customers with reliable strength calculation services that ensure the durability and safety of structures for industrial needs. We can help you optimise your structures and reduce material costs while ensuring that all safety requirements are met. Read more about our services here.
