When it comes to checking lifting equipment, the terms testing, inspection, and certification are often used interchangeably. However, these terms do not mean the same thing. In this article, we explain the differences.
Inspection
An inspection of lifting equipment is a visual examination carried out by a competent person. Based on a series of checks and measurements, the equipment is assessed to determine whether it is still safe to use and complies with the applicable standards. In most cases, the equipment does not need to be dismantled. For many types of lifting equipment, a visual inspection is mandatory once a year, although more frequent inspections may be required depending on how the equipment is used. The inspection findings are documented and recorded in an inspection report.

Certification
The certification of lifting equipment goes beyond a visual inspection. It is a comprehensive examination in which the equipment is checked against a wide range of criteria to determine whether it still complies with the applicable standards. During certification, the lifting equipment is partially dismantled and load tested to verify its rated Working Load Limit (WLL). This is not part of a standard inspection. The certification is documented, and the equipment receives a new inspection date, which is recorded both on the product and on the certificate.
Testing
Also referred to as proof load testing, testing forms part of the certification process. During a proof load test, the lifting equipment is subjected to a test load that exceeds its Working Load Limit. The exact test load depends on the type of lifting equipment. The purpose of the test is to verify that the equipment can still safely withstand its rated working load. If the equipment fails the test, it must either be repaired or removed from service.
In Summary
How often lifting equipment must be certified depends on the type of equipment and how frequently it is used. Many below-the-hook lifting accessories (equipment suspended from the crane hook) must be certified at least once every four years. In many cases, this also includes proof load testing. However, all lifting equipment must be visually inspected at least once a year. The manufacturer's instructions usually specify the minimum inspection and certification intervals.
Equipment above the hook, such as overhead cranes, must be certified annually, including proof load testing. During this process, an EKH inspection report is used to determine whether the crane still complies with the applicable standards and can be operated safely. Among other things, the brakes, wire rope, structural components, and electrical systems are inspected and assessed.
