Testing and Documentation

DOCUMENTATION

MATERIALS TESTING

We conduct our tests during production, and final inspections are always carried out by an independent inspection body.

MAGNETOSCOPIC CHECKS

Magnetic particle testing is the most commonly used method for detecting surface and near-surface defects, such as cracks in ferromagnetic materials like iron and steel. When the component is magnetized, leakage flux forms at surface discontinuities, causing magnetic particles applied to the surface to accumulate at these points. This creates a visible indication, resulting from the contrast between the background and the test material.

LIQUID PENETRANT TESTING

Liquid penetrant testing is one of the oldest non-destructive testing methods used to detect surface defects and can be applied to almost all metallic and non-metallic materials.

During this process, capillary action allows the penetrant liquid to enter any surface discontinuities in the material. After careful cleaning of the surface, a developer is applied, creating a reverse capillary action that draws the penetrant out of the defects, making them clearly visible.

ULTRASOUND TEST

Ultrasonic testing is particularly effective for detecting both internal and external defects in sound-conductive materials, and is therefore capable of identifying flaws throughout the entire cross-section of a component. This non-destructive acoustic testing method is used for quality control of pipes, welded joints, and cast parts, as well as for thickness measurement.

LOAD TESTING AVAILABLE UPON REQUEST.

ETS works in close collaboration with the leading certification bodies. This means that new projects are often discussed in advance and the required safety features are jointly defined. Tests are carried out on a daily basis to verify the construction of large-scale lifting systems, in accordance with applicable standards. The requirements for lifting equipment used in offshore environments are extremely demanding; as a result, all lifting accessories and equipment employed in this sector are consistently tested with loads exceeding their rated capacities. Continuous exposure to waves, wind, and harsh operating conditions places particular stress on lifting equipment, making proven and thoroughly tested safety features of paramount importance.

DOCUMENTATION MANAGEMENT

Documentation is as important as the product itself. For steel structures, the materials used must always be accurately documented. In fact, an undocumented component may lead to the rejection of the entire lifting equipment. The lifting system must always be supplied with complete documentation. All data and content must correspond to the design, and the documentation must include elements that verify the quality of the components and materials used, as well as details of the inspections carried out. While templates can be used to create documentation for simple standard structures, complex custom solutions require their own dedicated set of operating instructions.

To produce these instructions, documents from various sources must be compiled and the content properly formatted. The proofreading process typically takes place across multiple channels, such as email and phone, which can be time-consuming and make the workflow more complex. However, we have streamlined this process through semi-automated documentation management and archiving, as well as by organizing the workflow between the client and the manufacturer. The content—being the part that requires editing—is prepared separately from the document layout and is correctly positioned on the page only once exported to a PDF file.

Documents produced in this way are stored within the system and can be easily accessed and distributed directly from the program.

RISK ANALYSIS

Point 1 of Annex I of Directive 2006/42/EC (Machinery Directive) states:
“The manufacturer of the machinery or their authorized representative must carry out a risk assessment in order to determine the health and safety requirements applicable to the machinery. The machinery must also be designed and constructed taking into account the results of this risk assessment.”

This applies to manufacturers of machinery falling within the scope of this Directive, including lifting equipment. Manufacturers are required to perform a risk assessment, meaning they must identify all risks that may arise when the lifting device is used for its intended purposes, as well as any reasonably foreseeable misuse.

To prevent potential hazards and reduce the risk of dangerous situations, manufacturers must define the measures that can be taken to eliminate or minimize risks. Lifting equipment must be designed and manufactured in accordance with the results of the risk assessment and the measures identified.

Operators of lifting systems are also required to carry out a risk assessment for this equipment.

When performing this assessment, the following aspects must be taken into account:

interaction with other work equipment while the lifting device is in operation
risks that may arise from the use of the lifting equipment itself
risks that may arise between the lifting equipment and the working environment

Furthermore, when testing work equipment, operators must first determine the type and extent of the tests required, as well as when they should be carried out. Employers must also identify and define the requirements that personnel must meet in order to inspect and test the equipment.

The mandatory process of analyzing risks associated with lifting equipment can sometimes be highly demanding and time-consuming.
