A proof load test is executed on several items of lifting as well as rigging equipment. It is specially made to ensure that the machinery or heavy equipment has gone through mobile onsite testing and that it is capable of lifting the designated load without any issues. The test is commonly performed on a static pull test. A proof load test is done as a complementary test that guarantees structural as well as other safety guarantees.
Safety and efficiency are extremely important when rigging and load-lifting are involved. Therefore, it’s important to know if everything is going to work properly. A proof load test is the perfect solution. At Q Lift Wire Rope & Sling Company, we offer quality testing services designed to help you assess the efficacy of your load-lifting system so you can feel confident as you use it. Our experienced staff is ready to assist you, whether you are putting together a new load-lifting system or want to ensure your existing load-lifting system is still functioning correctly.
A compression test is any test in which a material experiences opposing forces that push inward upon the specimen from opposite sides or is otherwise compressed, “squashed”, crushed, or flattened. The test sample is generally placed in between two plates that distribute the applied load across the entire surface area of two opposite faces of the test sample and then the plates are pushed together by a universal test machine causing the sample to flatten. A compressed sample is usually shortened in the direction of the applied forces and expands in the direction perpendicular to the force. A compression test is essentially the opposite of the more common tension test.
The goal of a compression test is to determine the behavior or response of a material while it experiences a compressive load by measuring fundamental variables, such as, strain, stress, and deformation. By testing a material in compression the compressive strength, yield strength, ultimate strength, elastic limit, and the elastic modulus among other parameters may all be determined. With the understanding of these different parameters and the values associated with a specific material it may be determined whether or not the material is suited for specific applications or if it will fail under the specified stresses.
Missing or illegible sling identification; evidence of heat damage; slings that are knotted; fittings that are pitted, corroded, cracked, bent, twisted, gouged, or broken; other conditions, including visible damage, that cause doubts as to the continued use of the slings.
