INSPECTIONS AND EXAMINATIONS
The frequency of testing of lifting equipment may vary by country, both onshore and offshore.
Onshore, the minimum inspection time limits vary by country and can vary from 3-monthly to once every 4 years.
The actual period depend also on the intensity of use. By company, organization, project or situation, this should be assessed and recorded in a risk assessment.
Also in this case that the actual to handle term depends on the intensity of use and the circumstances.
For example, for the transport of offshore wind mills the lashing chains be used only once, because of the strong attack by the sea water, causing the tensioners get stuck.
All equipment, including operating equipment as stairs, hand tools, etc., is identified with a sticker or tag to the customer's wishes with RFID (radio frequency identification) and entered in the Equipment Data Management - System via the website Veltkamp.
Based on the risk assessment, intensity of use, projects, etc. is a schedule drawn up in consultation with the customer for inspections and examinations.
The user checks the equipment before use on possible defects.
Lifting equipment must be inspected and maintained annually by an expert further lifting equipment periodically (may vary by country) are inspected by a trained and certified person depending on the situation and expertise, can also be carried out inspections by trained users.
In specific situations by the customer designated employees can also be trained by our inspectors to perform independent inspections. In those cases Veltkamp can arrange the periodic examinations.
Standard procedure is that the inspections and investigations will be done on location.
In case of permanent offshore (rigs) is the equipment picked up in the relevant port and then maintain, the year colour adjusted and approved on a Veltkamp-location. One and other in accordance with planning.
Here is all the necessary residence time onshore is as short as possible in order to optimize availability.
In the case of sea transport are agreed on the basis of arrival and departure of a ship.
Often it is a combination of assets, storage racks, lifting equipment under the hook, hand and electric hoists.
Per part can the verification requirements and time limits vary by country. In some cases, Veltkamp along with selected local inspection companies and inspectors.
In a military organization are often specific circumstances. On the one hand equipment used intensively and also equipment can be stored for long time.
To ensure the continuity and safety at companies and operations within the framework of international and local regulations at minimal cost and minimal disruption of processes and availability.
Quality of Examinations
The safety factor of polyester webbing slings and round slings is 7:1. That is to say that the breaking load 7 x higher than the allowable working load (WLL = Working Load Limit). By the influence of sunlight (UV), the tensile strength initially decrease and stabilizes at a safety factor between 5:1 and 4:1 in accordance with chain and steel cable.
The lifetime of as well polyester and steel lifting equipment is determined in particular by overload, power surges, too high/low temperatures, sea water, chemicals, poor storage and lack of maintenance.
Often examination of lifting and cargo securing equipment has a disadvantaged position, despite the safety aspect and the extension of the lifetime.
Examinations on a test bench leads to overloading equipment of 1.5 to 2 times the WLL. This leads to rapidly ageing and does not guarantee any quality.
