TESTING OF CHAINS, WIRE ROPES, SLINGS & ACCESSORIES
We have installed since November 2013 in our main facility in Constanta, the first test bed in Romania with a maximum load test capacity of 300 tons-force and a maximum usable length of 12 meters.
With this test bed we can perform, as per customer request, destructive or non-destructive mechanical tests of load chains, mooring ropes, webbing slings, industrial magnets and also for for any other wire rope and chain accessories (hooks, shackles, sockets, etc.).
After the testing procedure is completed it is followed by the issuing of a Testing Certificate, which will contain all the data required by the employed method such as: certificate issuer, the customer's name, the performed testing type, the applied load, the elongation of the tested item, preset breaking test value and actual breaking load, the testing chart and the test results.
This service provided by us enables the customer to test both new and old products. If the tested products have an expired certificate, after passing the testing procedure, the operator in charge of the supervision and technical inspection of these equipments can safely issue a new technical bulletin for the tested products, thus getting a prolonged lifespan for those products with minimum costs, in a easy and 100% safe way.
The main advantage for the customer is testing of both newer and older products.
Important: For all lifting accessories with finished warranty, after testing, it is possible for the technician in charge, based on results, to extend service life, in a safe manner, fast and cheap!
The destructive tests can be performed on the following products:
- wire ropes up to 65mm in diameter (tensile strength class 1960N/mm2);
- wire ropes up to 68mm in diameter (tensile strength class 1770N/mm2);
- grade 80 chains with link size up to 48mm;
- webbing slings with maximum work load of 300t;
- mooring ropes with work load of 300t.
Non destructive tests are made for:
- wire ropes up to 102mm diameter;
- grade 80 chains with link size up to 68mm diameter;
- webbing slings with maximum work load of 150t;
- mooring ropes with maximum work load of 150t.
Our mechanical testing laboratory is accredited by Romanian Naval Authority. (ANR) since 2015.
The proof load test is the most common type of test required by our customers. The target load is set by entering the working load limit
(W.L.L. / S.W.L.) and by choosing a multiplying (design) factor. We are usually performing these kind of tests with a design factor of 2 times the rated W.L.L, in accordance with ASME B30.9 standard specs, but is possible to use different design factors.
At customer request, testing can be performed either to the breaking point of the tested item or the item can be released after reaching the target load.
The breaking test mode will push the tested item to destruction at the desired speed, set by PROlift's operator. Results will be compared with theoretical limits or manufacturers certificates.
The cyclic test parameters include test speed, upper load limit, upper load hold time, lower load limit, lower load hold time and number of cycles. This method is very useful to simulate real life scenarios and the behaviour of lifting sets on different load values.
The hold test setting allow the operator to set the target load (holding load) and how long the tested item should be held at the desired load value. This method is useful to check fatigue.
The testing certificate states in an explicit and easy to read manner all data related to the test performed.
