Frequently Asked Questions

Q: Can The Cranemaster be used to reduce dynamic hook loads when lifting through the splash zone?

A: Yes. The Cranemaster is designed to instantly respond to its surroundings, take up slack wire and reduce dynamic loads. Read about the use of the Cranemaster through the splash zone on our Applications site.

 

Q: What is the deepest operating depth for the Cranemaster?

A: As of today Cranemaster has been used at 2700 meters water depth and is designed to operate down to 3000 meters. The units can be designed to go deeper. Read more about projects at different water depths at our Project References site.

 

Q: Can the Cranemaster be used together with AHC?

A: Yes. The Cranemaster will work perfectly together with AHC that responds to inputs from an accelerometer. For other AHCs please contact us.

 

Q: What load range is applicable for the Cranemaster?

A: The different Cranemaster units cover a load range from 2-400T. Each unit is designed for a specific load range, and they can be arranged in parallel (doubling the load) or series (doubling the stroke) which gives you a vast variety of settings. Read more about the Cranemaster load range on our Product site.

 

Q: What additional information and equipment do you get when you order a Cranemaster unit?

A: The unit comes with certified shackles already mounted in each end. User manuals, certificates and project specific gas pressure instructions are sent, together with a gas filling set which include manometer, minimess hose, minimess tong and adapters.

Ernst-B. Johansen A.S can also provide booster pumps, digital manometers and service engineers if necessary.

The only thing our clients might need to provide themselves is nitrogen (class 2.6). This is only needed if the gas pressure needs to be adjusted.
