Abstract

A lifting device (100) comprises a casing (120) arranged to be displaced when the lifting device (100) is operated to lift of an object (110), and a string (130) extending out of the casing (120). The casing (120) is suspendable in the string (130). Moreover, the lifting device (100) comprises a maneuverer member (170), connected to the casing (120) and arranged to provide sensing signalling representative of a direction of the movement. Moreover, the casing (120) comprises a control unit (140) arranged to control the length of the string (130), and an electric motor (150) arranged to be controlled by the control unit (140) to cause the movement. Furthermore, the lifting device (100) comprises a battery (160) arranged to power the electric motor (150). The casing (120) has an opening (310) and is arranged to hold the battery (160) to obscure the opening (310) when the battery (160) is releasably mounted in the casing (120), whereby when the battery (160) is released from the casing (120), the opening (310) provides access to the string (130) and any parts inside the interior of the casing (120) that may cooperate with the string (130) or that are in the vicinity of the string (130).

Abstract

The present invention relates to a swivel comprising a static portion (1, 2, 124, 126) and a rotating portion (3, 120), which portions are coaxially rotatable about a longitudinal axis, wherein the static portion (1, 24, 124, 126) and the rotating portion (3, 120) electrically contact each other for transmission of electricity and/or signals/data between said portions, and which comprises an hole (30), which is centrally arranged and which runs coaxially along said longitudinal axis, for passage of a fluid, wherein the static portion comprises a housing (1) and a bottom (2), and the rotating portion comprises an axis part (3), which comprises an integrated bottom part (36) supported by said bottom (2), and that said axis part (3) comprises an integrated bottom part (36) which is supported by said bottom (2), and that said axis part (3) comprises a tubular upper part (32) extending upwards from said integrated bottom part (36), with said centrally arranged hole (30) for passage of a fluid is arranged.

Abstract

Provided are a method and an operation device for a manual control of a load suspended in the operations device (2) having a housing (20); a first connection device (5), at least indirectly carried by the housing (20), for the connection of the operation device (2) to a device for the lifting and lowering of the operation device (2) with its suspended load; a second connection device (21), at least indirectly carried by the housing, for the connection of the operation device (2) to the load which is to carried by the operation means; a handle (22), which is movably arranged in relation to the housing (20) and the load connection device (21) and which has a rest position between two end positions; a sensor (4) arranged inside the housing (20) for the detection of a motion by the handle (22) in relation to the housing (20) and the load connection device (21), which sensor (4) emits a signal corresponding to the movement of the handle (23) from its rest position; a control unit for receiving the signal and as a result thereof control the lifting and lowering of the operation device (2) with its suspended load, wherein the sensor (4) is an electromagnetic induction sensor.
