Load Testing
A proof load test is a process that requires the lift/pull of a specific type of material (the steel wire rope or chain) using specially designed proof load test machines. With the lift/pull, the system is able to measure the tensile strength and load capacity of the material based on elongation under force.
Load Testing
Proof Load Test performed on lifting gears, and/or equipment ensures the capability of lifting the designated load without any issues. From the static pull test, a controlled, measured application of force over a specific amount of time period, typically from 1.1 to 1.5 times of the designated load or the maximum set working load (MAWL), is given to the test-material / equipment, to ensure it exceeds the requirements.
To ensure accuracy of the verified proof load on the test gears, STL introduced the usage of Digital Load Cell* - the DLM Tensile Link (TL-3.0) together with the Telemetry Handheld (TW-3.0) to validate the Load Test Results.
*DLM digital test load cell introduced in STL on August 2023, for load test on test gear, like chain block/hoist, lever block hoist, plain trolley, snatch blocks, shackles and other rigging/lifting gears.
