Carrying out a tilt simulation of your load could prevent contingencies during shipping that might endanger the goods and the product being transported.
Tilt testing simulates the forces that might cause the goods to topple over or shift, with the purpose of designing a system that adequately secures them, attaining package stability.
Step by step guide for a tilt simulation of your load
Tilt testing involves a very simple premise: replicating the effect of gravity during the simulation. To this end, the load is tilted in a controlled manner, simulating the effects of this motion on the stability of the load.
The tilt simulation process can be broken down into three main steps:
- The simulation-ready sample is placed on a platform and secured using the load securement system to be evaluated.
- The load is tilted up to a certain angle. This angle is defined based on the coefficient of sliding friction, the target resistance and the mass in use.
- Once this angle is reached, the evaluated system must not exceed the deformation threshold for a certain amount of time. Otherwise, the test is considered to have failed and an adequate securement system must be found.
Additionally, it is possible to perform a tilt simulation of your load on palletized loads. One of two methods may be used in this case:
- Verification: consists of tilting the load up to the angle required to determine the coefficient of sliding friction, based on the acceleration that it must withstand. Once the inclination that is equivalent to the target G level is reached, that position must be maintained for at least 5 seconds.
- Characterization: involves tilting the load unit until failure. After knowing the angle of failure and the coefficient of sliding friction of the surface, it is possible to calculate the equivalent acceleration in order to define a maximum stability value.
Machines required for tilt testing
This testing method is easy to implement, since having any elevation system that is capable of moving the sample will suffice.
When evaluating lashing systems, it is necessary to use machines specifically designed for tilt simulation. However, when testing packages, any system or machine that allows one part of the sample to be elevated may be used.
Indeed, the EN12195 standard on tilt testing makes no mention of the machinery to be used; instead, it outlines a simple testing procedure: the sample is placed on a flat surface and tilted while it is possible and the sample can resist.
For this reason, package stability testing systems are many and varied, including non-controlled elevation systems such as block & tackles and forklifts.
This said, these systems do not guarantee reliable results or allow for test repeatability.
The goal of the InnTilt system by Safe Load is to address this inadequacy – a system that is specifically created for an intuitive performance of this simulation, enabling the obtainment of accurate results and designed as per the EN12195 standard.
This machine is, therefore, suitable to quickly compare different samples (for example, during design) and measure stability at the end of the production line without the need for more components.
In addition, this system is highly recommended for quality control systems and guarantees test repeatability, making it a useful tool to study the way to optimize your packaging to ensure load stability.
