Maximum Working Load (MWL)

Never, under any circumstances, exceed the capacity or Maximum Working Load (MWL) of any piece of equipment. The maximum working load may be found in our catalog, on our website, or through our technical service department. Loads above the MWL can cause the equipment to fail suddenly and unexpectedly.

Maximum working loads are a 4:1 coefficient ratio of the breaking load. Human suspension applications require a 10:1 ratio.You must carefully read, understand, and follow all of the warnings and instructions in the User Manual provided by Harken in order to avoid an accident.
