A wire singulating device includes a carrier member and a retention feature. The carrier member has a front edge and an opposite rear edge. The front edge defines an opening to a slot that extends at least partially towards the rear edge. The carrier member is configured to move relative to a wire bundle that includes plural wires such that the front edge engages the wire bundle. The slot is configured to receive one wire of the wire bundle therein. The retention feature is coupled to the carrier member and juxtaposed relative to the slot to retain the wire within the slot as the carrier member moves away from the wire bundle to separate the wire from the wire bundle.

An apparatus for hoisting and positioning a load in a self-balanced manner regardless of the position of its center of gravity. The apparatus comprises an upper platform adapted for being hoisted from a general hoisting point, a lower platform adapted the attachment of a load to be hoisted and positioned, and a six degrees of freedom actuator comprising six variable length tendons, adapted for moving the lower frame with respect the upper frame in the three directions of the space and tilted around the three axis of the space. A configurable counterweight system supported by the upper platform is arranged for modifying the center of mass of the apparatus over a horizontal plane, and processing means are configured for dynamically calculating a desired position of the counterweight system, for balancing the apparatus with the respect to a general hoisting point.

A periphery monitoring apparatus for a work machine, includes a plurality of object detection devices configured to detect an object around the work machine, and a calibration part configured to perform calibration of coordinate systems of the plurality of object detection devices, wherein the calibration part is configured to sequentially execute a plurality of calibration algorithms for the calibration in ascending order of processing time duration and number of manual operations, until the calibration is completed.

The invention relates to an interconnection unit (124) connecting modules of a container coupling arrangement (120), which are configured to be releasebly attached to a lifting arrangement (110) and to couple a container (130) with the lifting arrangement, wherein the modules comprise at least a head block module (122) and a spreader module (123), the interconnection unit comprising one or more head block fastening units (1241, 1242), which are provided with an anchor point (1243, 1244), wherein the anchor point is configured to releasebly attach to the head block module of the lifting arrangement, each head block fastening unit movably coupled to a corresponding displacement unit (1245, 1246), the interconnection unit (124) further comprising the one or more corresponding displacement units, being movably coupled to the corresponding head block fastening unit and movably coupled to a spreader fastening unit (1247), the interconnection unit further comprising a plurality of locking arrangements.
