摘要:
A lifting apparatus, especially a cable traction mechanism, comprising a base frame that has at least two base plates, further comprising at least two longitudinal beams which have a first end and an opposite second end and which interconnect the base plates and keep the same apart from each other. The lifting apparatus, especially a cable traction mechanism, comprises a simple design and can readily be mounted, dismounted, or modified by detachably fastening the first end and the second end of the longitudinal beams to the base plates in such a way in an operational state of the lifting apparatus and designing one of the at least two base plates in such a way that the longitudinal beams can be inserted or removed in the direction of the longitudinal axis thereof when mounting, dismounting, or modifying the base frame.

A lifting apparatus, especially a cable traction mechanism, comprises a base frame that has at least two base plates and at least two longitudinal beams that interconnect the base plates and are spaced apart from each other. Attachment elements are mounted on the base plates by means of holding parts. The lifting apparatus, especially a cable traction mechanism, is characterized by a modular design, where the holding parts are arranged as extensions of the longitudinal beams.

A lifting apparatus, especially a cable traction mechanism, comprising a base frame that has at least two base plates, further comprising at least two longitudinal beams that interconnect the base plates and are spaced apart from each other, and at least one attachable cross-member for cable reeving parts that is fastened to the base plates and extends substantially parallel to the longitudinal beams. Multiple mounting points, to which the attachable cross-member for cable reeving parts can be alternatively and detachably fastened, may be arranged on each of the base plates to promote modularity of the lifting apparatus.

A hoisting device, especially a cable or chain block, with a hoisting transmission having at least one shaft and with a hoisting load measuring mechanism. In order to determine the hoisting load as accurately as possible and possibly independent of the reeving and without additional structural height, the hoisting load has at least one sensor for detecting the deformation of the shaft produced by the hoisting load and the detected deformation is used as a quantity in determining the hoisting load.

A flow regulating valve for negative pressure has a housing (1,2) which is divided into first and second chambers(4,5) by a suspended membrane (3). The first chamber has an outlet opening (6) at which a valve seat (22) is positioned. An electromagnet (12) with a disc armature (14) is mounted in the second chamber. The membrane supports at its center a shutting plug (9). The disc armature is linked to the center of the membrane via a lever system which transmits movement of the disc armature. The disc armature is formed as a hinged armature.

The invention concerns a back-flow check valve having a flat valve seat with a plurality of openings which are covered by a head of a mushroom-shaped closing member manufactured of a soft-elastic material. A fine mesh sieve is arranged between the head of the closing member and the valve seat for covering the openings. The fine mesh sieve prevents the head from being partially pulled into the openings so that knobs would be formed on an interior surface of the head.
