摘要:
Eine Vorrichtung zum Trimmen einer Liekleine (114) eines Segels (100) weist eine Spanneinrichtung (14), mit der die Liekleine (114) verbindbar ist, und einen Stellantrieb (16) zum Bewegen der Spanneinrichtung (14) in einer ersten Richtung, um die Liekleine (114) zu spannen, und in einer zur ersten Richtung entgegengesetzten zweiten Richtung, um die Liekleine (114) zu entspannen, auf. Der Stellantrieb (16) weist einen Elektromotor (22) auf, der mit einer Energieversorgungsquelle (24) verbunden bzw. verbindbar ist. Der Stellantrieb (16) ist selbsthemmend.

A capstan winch (10) includes a reel assembly comprising a reel (12), which rotates, and two generally annular floating flanges (20) which are supported so that the planes in which they rotate converge towards one another, which has the effect of creating an apparent axial movement of the flanges with respect to the reel as they rotate together. The cylindrical surface of the reel (12) is provided with alternating lands (19) and grooves (18) and the floating flanges (20) have formed on them alternating inclined faces (26 and 24) which correspond with lands (19) and grooves (18). The inclined faces (24 and 26) are angled so that the faces (26) which correspond to each land (19) on the reel (12) are generally parallel to one another. The inclined faces (24) which correspond to each groove (18) converge. Consequently, substantial lateral forces are exerted on a cable being wound onto the reel (12) only when the cable overlies the grooves (18) and frictional forces on the cable are minimised.

This device comprises a drum (42) intended to be driven in rotation about a central axis (B-B'), the drum (42) defining a circumferential casing (50) for winding the elongate element about the central axis (B-B'), the elongate element being intended to form at least one turn about the central axis (B-B') on the circumferential casing (50). It comprises a mechanism (44) for driving the or each turn of the elongate element over the circumferential casing (50). The driving mechanism (44) comprises at least one assembly (80) for moving the turn in a moving direction (D) that forms a non-zero angle with the local axis of the turn, taken in a bearing region of the turn on the moving assembly (80).

摘要:
The invention concerns a device for manoeuvring and storing a rope, in particular a ship hawser. Said device comprises a vertical drum (2) engaging with means (3) for rotating same. Said vertical drum (2) comprises a tubular body (21) that comprises two opposing surfaces: - an outer surface (211), around which said rope is capable of being wound, and - an inner surface (212), delimiting at least a lower portion (51) of a vertical passage (5). Said vertical passage (5) comprises two opposing ends: - a lower end (511) provided with a through-opening that extends through said tubular body (21), and - an upper end (522) associated with a system (4) for storing said rope and for manoeuvring said rope in translation along said vertical passage (5).
