Frequently Asked Questions

Q1 Is it easy to maintain?
The belts are the only consumable items. In the event of failure, the belt reel units can be replaced individually through the top of the box.
Q2 Doesn’t dirt or water build up in it?
During cargo work, the lid is kept adequately tight by tensile force provided by compressed air. Any water that enters it during sailing will be expelled via its drain outlets.
Q3 Is the installation work troublesome?
No. It’s just a matter of fastening the box to the deck and fitting up a branch tube from the ship’s compressed air tubing.
