CHAINS, WIRE ROPES, WEBBING SLINGS, MOORING ROPES AND ACCESSORIES TESTING
We have installed since November 2013 in our main facility in Constanta the first test bed (bench) 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 tests of load chains, mooring ropes, webbing slings and also for any other wire rope and chain accessories (hooks, shackles, sockets etc.).
After the testing procedure is completed it is followed by the issuance of a Certificate of Testing, which will contain all the data required by the employed method such as: the certificate issuer, the customer's name, the performed testing type, the applied load, the elongation of the tested item, the preset breaking load value and the actual breaking load, the testing chart and the test results.
Testing certificate states in an explicit and easy to read manner all data related to the performed test.
This service provided by us enables the customer to test both new and old products. In case the tested products have an expired certificate, after passing the testing procedure the operator in charge of the supervision and technical inspections of those 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.
Destructive tests can be performed on the following products:
- wire ropes up to 65 mm in diameter (1960 N/mm2 tensile strength);
- wire ropes up to 68 mm in diameter (1770 N/mm2 tensile strength);
- chains (grade 80) up to 48 mm in diameter;
- webbing slings with minimum breaking load up to 300 tons;
- mooring ropes with minimum breaking load up to 300 tons.
The non-destructive tests can be performed on the following products:
- wire ropes with a maximum diameter of 102 mm;
- chains (grade 80) with a maximum diameter of 68 mm;
- webbing slings with a working load limit of max. 150 tons;
- mooring ropes with a working load limit of max. 150 tons.
Proof load test is the most common type of test required by our customers. Target load is set by entering the working load limit (WLL) and by choosing a multiplying factor. We are usually performing these kind of tests at a multiplying factor of 2 times the rated WLL of the item to be tested, in accordance with ASME B30.9-2010 Standard.
At customer's 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.
Breaking test mode will push the tested item to destruction at the desired speed set by the operator. Cyclic test parameters include test speed, upper load limit, upper load hold time, lower load limit, lower load hold time and cycles number. Hold test settings allow the operator to set the target load (holding load) and how long the tested item should be held at the desired load value.
Our mechanical testing laboratory is accredited by Romanian Naval Authority.

WIRE ROPES TERMINATIONS (SOCKETS) FITTING
Beside the classic wire ropes end connections (eyes formed with wire rope clips, braided or swaged) there are various other ropes end connections, such as sockets. Terminating a wire rope with this kind of end connections can be achieved by using:
- a swaging machine;
- inner socket wedges;
- Wirelock resin.
The wire rope end connections that are fitted using a swaging machine are characterized by a sleeve which is slid onto the wire rope's end and it is fitted to the wire rope using a swaging machine. The swaged socket is mainly used for small diameters wire ropes.
The wire rope end connections that are mounted using inner wedges can easily be fitted on site. By using a wedge the wire rope's end is jammed into a tapered socket. As the load increases, the wedge is pulled deeper into the socket and it exercises normal clamping force on the rope. The loose end of the wire rope is then secured with a wire clip. The use of this kind of socket is highly popular as an end connection for the hoisting ropes on mobile cranes.
The wire rope end connections that are fitted using Wirelock resin are very reliable and efficient wire rope end connections. In a pull test they achieve the highest breaking loads compared to other terminations and furthermore, tension-tension fatigue endurance is excellent.
They are used extensively in applications which require the end connections to withstand high, continuous tension-tension stresses, as it is the case with the suspension ropes of the crane booms (ship mounted winches, bridges).
WIRE ROPES SWAGING AND SPLICING
We are operating the largest hydraulic swaging machine for mechanically spliced wire ropes not only in Romania, but also in the South East Europe, with a max. capacity of 2.000 tons-force (WIROP-2000) and also 6 hydraulic swaging machines with a max. capacity of 300 tons-force (WIROP-300).
By using these machines we can manufacture wire rope slings with eyes at both ends, with or without thimbles, by swaging with cylindrical or conical aluminum or steel sleeves (Flemish Eye type), for any wire rope diameters from 3 mm (0.01") up to 102 mm (4") in compliance with the latest European standards in our field of expertise.
Main feature of conical steel ferrules is that they allow the plaiting of the wire rope eye and swaging under the sleeve to prevent the wire ends from becoming disheveled. By using this type of ferrules we can manufacture "Flemish Eye" wire rope slings that have 25% higher working load limits for the same type of wires when compared to using the aluminum sleeves.
