  2. Proof test - Wikipedia

    en.wikipedia.org/wiki/Proof_test

    A proof test is a form of stress test to demonstrate the fitness of a load-bearing or impact-experiencing structure. An individual proof test may apply only to the unit tested, or to its design in general for mass-produced items. Such a structure is often subjected to loads above those expected in actual use, demonstrating safety and design margin.

    and assuming the test data is taken from a statistically valid test method, the data is to be determined via statistical means to derive the Load resistance model, for the anchor. There are adequate load case coefficients available to estimate sling angle load amplification , suction from the casting bed , and various dynamic transportation ...

    en.wikipedia.org/wiki/Lifting_equipment

    Lifting equipment, also known as lifting gear, is a general term for any equipment that can be used to lift and lower loads. [1] Types of lifting equipment include heavy machinery such as the patient lift , overhead cranes , forklifts , jacks , building cradles, and passenger lifts, and can also include smaller accessories such as chains ...

    Two days later, it underwent a cryogenic proof test to destruction, bursting at 8.5 bar (123 psi). [157] [154] [158] GSE 4.1 was first spotted in August 2021 and was the first ground support equipment (GSE) test tank built, made from parts of GSE 4. [139] It underwent a cryogenic proof test in August 2021 before it was rolled to the Sanchez ...

  6. Static load testing - Wikipedia

    en.wikipedia.org/wiki/Static_load_testing

    Static load testing is an in situ type of load testing used in geotechnical investigation to determine the bearing capacity of deep foundations prior to the construction of a building. It differs from the statnamic load test and dynamic load testing in that the pressure applied to the pile is slower.

  7. Safe Load Indicator - Wikipedia

    en.wikipedia.org/wiki/Safe_Load_Indicator

    A Safe Load Indicator (SLI) or an Automatic Safe Load Indicator (ASLI) is a device which is installed on mobile or portal cranes to alert the operator if the lift is exceeding the safe operating range of the machinery. [1] In some cases, the device will physically lock the machinery in circumstances it determines to be unsafe.
