Abstract: The present invention relates to lifting gear, more particularly a crane, such as a rotary tower crane and/or mobile crane, having a supporting structure, a determination device for determining a load state and/or an operating state of the supporting structure, and a control unit for controlling actuators of the lifting gear depending on the determined load state and/or operating state, wherein the actuators are allocated to the supporting structure for the active bracing and/or deformation of the supporting structure in a variable manner during lifting gear operation, and the control unit is configured to temporarily and variably brace and/or deform the supporting structure by means of the actuators depending on the detected load state and/or operating state in order to relieve the load on supporting structure parts which are subject to high load.

Abstract: A lifting gear having a hoist cable, which descends in at least two strands from a tackle support, in particular a trolley, and also having a bottom block, which is reeved on the hoist cable and on which a load-bearing means is fitted. The strands of the hoist cable are at a different distance apart from one another at the bottom block than at the tackle support. Arranged between the bottom block and the tackle support is a strand-distance guide for compensating for the different strand distances at the bottom block and at the tackle support and for guiding the cable strands substantially parallel to one another on one side of the strand-distance guide and splayed apart in a V shape in relation to one another on the opposite side of the strand-distance guide.

Abstract: A crane (2), more particularly a mobile fast-erecting crane, having at least one supply connection to which a supply line (16), more particularly a power cable, can be connected, wherein the supply line can be wound on a cable drum (15), which can be mounted on a drum mount (10) on the crane, with the cable drum being mounted to rotate on a drum support frame (18), which has running gear (18) for moving the cable drum over the ground and which has releasable mounting means, shaped to match the drum mount of the crane, for separably mounting the drum support frame on the drum mount of the crane. The invention further relates to a cable drum unit for winding a supply line (16) of a crane (2).

Abstract: The invention relates to a mobile construction crane comprising a superstructure and an undercarriage, wherein one or more electrical consumers are provided in or at the superstructure, wherein a supply of the one or more electrical consumers with electrical energy takes place by at least one current generator installed in the undercarriage.

Abstract: The invention relates to a tower crane having a tower which carries a jib, from which a hoisting cable runs off, wherein a guying system is provided and runs, at least in part, along the tower and is spread out, by means of guy supports, in a direction transverse to the longitudinal center plane of the crane, this plane running through the tower and the jib, wherein at least one pair of guy supports which are spread out in a V-shaped manner are articulated on the tower, between the lower end of the latter and the jib.

Abstract: This disclosure describes methods, devices, and systems related to routing packets over enterprise network sites. A method may be disclosed for routing packets between hosts at a first site and hosts at a second site in a network using a firewall. The method may comprise receiving a request, in a first packet, from a first router to send one or more packets to two or more hosts at the second site. The method may comprise receiving a first sub-network prefix, in a route advertisement, corresponding to two or more hosts at the first site from the first router, and receiving a first community value, in a first advertisement, associated with the first sub-network prefix. The method may comprise generating a first local preference value based at least in part on the first community value. And the method may comprise sending the request, first sub-network prefix, and first local preference value to a second router, in a second advertisement.

Abstract: An interactive education system for teaching patient care to a user is described. The system comprises a patient simulator; a virtual instrument for use with the patient simulator in performing patient care activities; means for sensing an interaction between the virtual instrument and the simulator, and means for providing feedback to the user regarding the interaction between the virtual instrument and the simulator. In one aspect, the system includes a maternal simulator, a fetal simulator, and a neonatal simulator.
