Abstract: Apparatus for controlled lowering or moving of a suspended load, in particular a lifeboat in a davit, from a position near a ship's side or the like to a launching position, comprising a flexible element (1) extending in two or more portions (folds) (1A, 1B, 1C, 1D) between two end pieces (11, 12) which in turn are connected to tension transfer members. This partly corresponds in principle to a single or multiple block and tackle arrangement. The distance (D) between the end pieces (11, 12) capable of being increased in a controlled manner under the influence of tensional forces due to the load. The flexible element has the form of a belt (1), and at least one of the end pieces (11, 12) is provided with one or more transverse bolt(s) (2A, 2B, 4), about which the belt is wound in a substantially U-shape and is designed to slide round in its longitudinal direction. A manual braking device (5) presses two portions (folds) of the belt (1C, 1D) against each other at a place where these move in mutually opposite directions under the controlled lowering or movement in order to bring about a braking effect.

Abstract: Brake (1) having permanent magnets for launching life-saving equipment, characterised in that it comprises: - two coaxial parts having relative rotational movement therebetween around the common shaft (4), - wherein a first part comprises permanent magnets (6), and - wherein the second part comprises at least a solid body (9) of paramagnetic material adjacent to said magnets (6). such that the relative displacement thereof within the extent of the lines of flux induces eddy currents generating forces in opposition to the relative movement between the two parts.
