摘要： The invention relates to a cable winch, preferably a sprocket-type large cable winch for deep-sea applications, having a cable drum, the end faces of which are enclosed by end discs, and having at least one drive unit for driving the cable drum. The drive unit comprises a motor and a gear mechanism which on the output side drives an output wheel, said wheel being in engagement with a drive wheel, preferably in the form of a sprocket, provided on one of the end discs. According to the invention, the output wheel of the drive unit is arranged between motor and gear mechanism, and the motor and the gear mechanism extend towards different sides of the end disc.

摘要： A winch is provided that includes a frame and a winch drum mounted for rotation relative to the frame; a gearing via which the winch drum can be rotated by a drive motor attached to the winch, wherein the gearing includes a gear shaft; a first brake that includes a first brake body and a second brake body which is non-rotationally connected to the gear shaft. The first and second brake bodies can be pressed against each other in order to achieve a braking effect based on frictional engagement. A second brake is also provided that includes a third brake body and a fourth brake body which is non-rotationally connected to the gear shaft and/or the second brake body. The third and fourth brake bodies can be pressed against each other in order to achieve a braking effect based on frictional engagement.

摘要： A traction winch for winching an elongated article having a high-tension end connectable to a load and low-tension end connectable to a storage device includes two or more rotatable drums arranged adjacent to each other with their rotational axes substantially parallel, each of them having a plurality of parallel, circumferential sheaves with groove, the sheaves being axially offset with respect to each other to allow wrapping of the elongated article around the sheaves of both drums in a spiral fashion. The sheaves includes fixed sheaves, stationary relative to their underlying drum, and rotatable sheaves, rotatable relative to their underlying drum. The majority of the rotatable sheaves of at least one of the drums is arranged adjacent to each other on a high load supporting side of the winch and the rotational velocity of at least one of the rotatable sheaves is reducible by means of at least one braking device.

摘要： A fall-arrest safety anchorage has a safety line drum 10 and braking mechanism assembled to a spine plate (1). The braking mechanism comprises a rotatable brake component (2) and fixed brake components (1,7) which are relatively rotated against a frictional resistance on engagement of a centrifugal clutch if the unwinding speed of the drum exceeds a certain value. The clutch comprises coupling elements (17) and abutments (16) which lie within or extend into an aperture in the spine plate (1).
