Introduction to Proof Load Testing

Lloyds British International offer Proof Load Testing and Overload Testing Services. Load Testing involves applying a load to a structure, material, or piece of equipment to verify its strength. A proof load test is usually expressed as a percentage of the working load limit (WLL) or safe working load (SWL) that the equipment is designed to withstand.

Proof Load Testing of lifting equipment is required to ensure that items of lifting equipment can perform to the required British or European standard, and in accordance with the designed safe working load (SWL) or working load limit (WLL) calculated by the original equipment manufacturer (OEM) during the design and manufacturing process.

Typically, Lifting Equipment has to be tested in accordance with LOLER 1998 and the relevant British or European Standard for the following reasons:

  • After the equipment has been manufactured, Installed, Repaired, Modified or Refurbished
  • Following an incident
  • Periodic testing may be specified in some British or European Standards (i.e. BS7121 for Lorry Loader and Mobile Cranes)
  • A competent person may also require a proof load test is carried out during a Thorough Examination process to determine whether a piece of lifting equipment is safe to use.


The exact requirements of a Proof Load Test or Overload Test can vary depending on the standards, equipment, and individual requirements of the customer or original equipment manufacturer (OEM).

Lifting equipment is designed and manufactured in accordance with a British, European, International, or Manufacturer (OEM) Standard. Both the relevant Standard and LOLER requires lifting equipment to be tested to verify and certify the Working Load Limit (WLL) or Safe Working Load (SWL). All lifting equipment has to be tested at some point during the design, manufacturing, installation process, or for any other reason given by a competent person or to ensure compliance with LOLER 1998. The list below includes some, but not all, lifting equipment which requires a proof load test.
