Proof Load Testing FAQs

  • What is proof load testing?

    A proof load test is performed on various lifting and rigging devices to ensure they can withstand the design load safely and without failure or yielding.

  • How is a proof load test performed?

    Force is applied for a designated time ranging from 1.1 to 1.5 times the design load or maximum allowable working load (MAWL). We perform all tests on a machine capable of linear tests up to 400,000 lbs.

  • What are some common lifting products tested?
    • Overhead cranes and supporting runways
    • Patient hoists
    • Motor vehicle lifts
    • Building cleaning cradle and suspension equipment
    • Goods and passenger lifts
    • Telehandlers and forklifts
    • Lifting accessories
    • Chain blocks
    • Web slings
  • When is a proof load test required?
