A descender device for manually raising and lowering an object or person on a rope has a housing (which has opposing first and second ends and opposing side walls), an attachment means (provided at the first end of the housing and configured for attachment to an anchor point or to the object or person to be raised or lowered), rope entry and exit ports (at the second end of the housing), a drive pulley (around which the rope may be engaged), a centrifugal brake (configured to limit the speed of rotation of the drive pulley), a gear assembly, a wheel (arranged to be gripped by a user of the device), and a rope retaining means provided on an outside of the housing. The wheel is connected to the gear assembly. The rope retaining means comprises a projection and at least one groove.

The invention relates to an abseiling device comprising a bidirectionally rotatable guiding arrangement (25) for guiding a pulling means (26); further comprising a braking mechanism (30) that is coupled to the guiding arrangement (25); a driving means (34; 35) can be connected to the guiding arrangement (25) so as to actuate the guiding arrangement (25). In order to create an abseiling device that prevents an individual from being injured or parts of the abseiling device from being damaged during rescue operations in particular of people, a mechanical torque limiter (33) decouples the driving means (34; 35) and the guiding arrangement (25) or the pulling means (26) when the torque exceeds a certain threshold value.

The invention relates to a balancer (1) for raising, holding and lowering a load, comprising a cable drum (7) which can be rotated in a manner actuated by pressure medium and has a cable for bearing the load, which cable can be unwound from and wound onto said cable drum (7), and has a device for emergency braking of the cable drum (7) if a defined rotational speed is exceeded, which device for emergency braking comprises at least one locking element (16) which is fastened to the cable drum (7), is held in a freewheeling position in a spring-loaded manner and can be moved into a deployed locking position in a manner which is actuated by centrifugal force, in which locking position the rotation of the cable drum (7) is blocked by virtue of the fact that the locking element (16) is in engagement with a stop which is stationary relative to the cable drum (7). The balancer (1) according to the invention is distinguished by the fact that, after its triggering, the locking element (16) is held in a deployed position when said locking element (16) and the stop which interacts with it move out of engagement.

An abseiling device, includes a guide arrangement that can be rotated in two directions for guidance of a traction means. A braking device is coupled to the guide arrangement, where a drive means is connectable to the guide arrangement for actuating the guide arrangement. A torque limiter with a first coupling body and a second coupling body. decouples the drive means and the guide arrangement when a threshold value of a torque is exceeded. The first coupling body is displaced in translation relative to the second coupling body between a coupling position and a decoupling position.

An electromechanical actuator (1) includes a motor (3) driving a shaft (4), a piston (5) movable in an axial direction between a low and high positions and an upper sleeve (8) slidably mounted on the shaft (4) below the piston (5). A lower sleeve (7) is attached to the shaft (4) and radially extending arms (9) are attached to the shaft (4) between the sleeves (7, 8). Flyweights (10), elongated in the axial direction, are slidably mounted on the arms (9). Lower and upper ramps (11, 12) contact the axial ends of the flyweights (10) and start from one of the sleeves (7, 8) and extend away from the shaft (4) towards the other sleeve (7, 8) such that the flyweights (10) are interposed between the ramps (11, 12) to maintain the spacing of the sleeves (7, 8). An electromagnet (14) holds the piston (5) in the high position.
