Portable Digital Crane Dynamometers

for on-board and on-site Proof Load Dynamic Testing of Ship, Offshore, Port, Construction & Industrial Cranes, Winches, as well as Bollard Pull Testing and other applications ie wire rope / cable breaking strength, pull out tests, etc.

Ship & Offshore Crane/Derrick on-board load & pull testing/inspection has never been easier.
The best alternative to weights. Accurate, user friendly, and fast. That is all that is needed.
Proof load testing is an essential part of any inspection, repair and maintenance programme. In many countries proof load testing of lifting equipment such as cranes is a mandatory requirement. A successful proof load test instills confidence in customer, operator and owner.
