Field Test
There is no ASME standard for davit cranes. OZ Lifting Products davit cranes have a minimum 3:1
design factor. We individually load test and certify every davit crane to 125% of the rated capacity.
A test certificate is generated that includes the serial number and a photo of the davit under load.
If a load test is required on site, we recommend contacting a civil engineer to determine if the base
has been properly mounted to a secure location. We provide the information on the moment a base
would pull away from the mounting bolts.
