6.12.1 Gangway system

The system works through a hydraulic control unit located in a technical room on the starboard side.

The system is fed by the pumps that, by sucking oil from the tank, send it through the solenoid valve blocks and pipes to the hydraulic pistons activating the gangway. On the aft transom starboard, is installed the receiving photocell, which detects the signal sent by the radio control and transfers it to the hydraulic control unit.

1. Gangway
2. Gangway push button panel
3. Electrohydraulic control unit

The radio control must be directed towards the photocell and no obstacles must stay in their way.

If the automatic gangway retraction control does not work, for alignment and reentry it is possible to close the gangway manually using the procedure described below, which requires two operators.

Operator 1 will have to act on the electric control unit located inside the hull’s system room while Operator 2 manages operations from the control panel or remote control while maintaining constant visual contact with the gangway.

Phase 1:

• Operator 1: insert the key in the "Safety By-pass" selector on the electric control unit box;
• Operator 2: return the second extension.

Phase 2 (With the selector kept in the "Safety By-pass" position):

• Operator 1: keep the rotary selector in the by-pass position.
• Operator 2: press the "Raise" or "Lower" button until it reaches a perfectly horizontal alignment "0 position" between the first extension and the box (it is possible to use a spirit level).

Phase 3 (With the selector held in the "Safety By-pass" position):

• Operator 1: keep the rotary selector in the by-pass position;
• Operator 2: press the “Automatic re-entry” button while maintaining visual contact with the gangway in order to start the re-entry of the first section of the gangway inside the box. If necessary, correct the alignment of the gangway in order to make it return to a perfectly horizontal position.

Phase 4

• Operator 1: Remove the key from the "Safety By-pass" selector.

CAUTION

In order not to jeopardize the walkway of the seals, perform the washing in the box avoiding that water enters under pressure.

CAUTION

The gangway must always be closed during navigation.
