摘要:
L'invention concerne une plateforme hydraulique de mise à l'eau et de levage d'annexe de bateau, la plateforme (2) comprenant un plancher (20) et un cadre (22) de maintien s'étendant, dans le plancher (20) étant réalisé une découpe (15) de réception d'une passerelle (6) d'accès à un quai. Avantageusement, la plateforme (2) comprend des moyens de déplacement en translation (7, 28) de la passerelle (6) par rapport au cadre (22) le long d'une direction de translation (X), ces moyens de déplacement en translation comprenant au moins un rail (28) fixe, s'étendant selon la direction (X) au niveau de la découpe (15), et un chariot (7) mobile le long du rail (28), la plateforme (2) comprenant encore des moyens de déplacement en rotation (10, 11, 12) de la passerelle (6) par rapport au cadre (22) autour d'un axe de rotation (A), ces moyens de déplacement en rotation (10, 11, 12) de la passerelle (6) sont au moins en partie montés sur le chariot (7) . L'invention concerne en outre un vaisseau, tel qu'un catamaran, comportant une telle plateforme (2) de mise à l'eau et de levage d'annexe.

An access apparatus (2) for enabling transfer of personnel between a seaborne vessel (6) and an offshore installation is disclosed. The apparatus comprises a body (18) adapted to be mounted to a deck (4) of a seaborne vessel, clamping members (10) adapted to grip a buffer tube, mounted to a support of an offshore installation, therebetween, to limit vertical movement of the buffer tube relative to the clamping members, wherein the clamping members can pivot relative to the body about a respective single pivot axis extending in at least two mutually perpendicular directions.

A container and car carrying reefer vessel A refrigerated-cargo vessel for transporting fruit and like foodstuffs has a roll-on/roll-off ramp (2) and a plurality of decks including an upper weather deck(50), and two or more lower decks (10, 20, 30, 40) for receiving palletised cargo. The weather deck (50) is equipped for receiving containers. A grating allowing ventilation of cargo placed on the grating is part of removable cargo platforms (8). The platforms are transportable via the ramp (2) by transport drive units(100).The cargo, like pallets loaded with fruit boxes, are loaded or unloaded at high capacity.
摘要:
A closed-loop hydraulic control system that may arrest the motion of attached devices in the event of loss of electrical or hydraulic power or in the event of an emergency. Gangways from a ship to a platform and ladders on fire trucks may have hydraulic control systems that allow for free motion in several different directions in order to keep stability in rough waters or shifting ground. If the gangway or ladder begins to fall due to loss of hydraulic power or a failure in the securing of one end, the closed-loop control system may detect these situations and actuate the closing of valves to limit or stop the falling motion of the gangway or ladder. Various control or damping algorithms may be employed to yield a desired and controlled arresting of motion so as to prevent injury and damage.
摘要:
The invention relates to a device for a watercraft for picking up and launching boats. Said device comprises an extension arm that is coupled in such a manner that it can swing freely on the watercraft, that extends at an acute angle in relation to the surface of the water and floats in water by means of floats. Said extension arm comprises guide tracks for a boat retrieving device that is maintained on the extension arm in a longitudinally displaceable manner. Said boat retrieving device comprises a holding head that is articulated in a displaceable manner on a running part guided on the guide rails, about an axis that is horizontal and approximately transversal in relation to the extension arm. Said running part is connected to the drive means for longitudinally displacing the boat retrieving device. The holding head comprises at least one adjusting means that acts upon its adjusting movement about the horizontal axis.
