System for controlling the loading or unloading a cable [2] or the like onto a drum [3], wherein the drum [3] has a known first rotation axis loading or unloading the cable, the system also comprises an imaging means [1] aimed at the cable [2] from a position at a distance from the drum rotation axis, the imaging means [1] being adapted to measure the direction of the cable [2] relative to the rotational axis of the drum. The imaging means can be constituted by a video camera.

The present invention relates to a cable winch, in particular a hoisting gear winch of a hoist, comprising a cable drum, an entry guide for a cable to be wound onto the cable drum, and an actuating drive for adjusting the entry guide relative to the cable drum. The invention also relates to a hoisting device, in particular in the form of a crane, having such a cable winch. According to the invention, a detection unit for detecting an image of the progression of the winding of the cable wound onto the cable drum is provided and the control unit is designed to adjust the entry guide relative to the cable drum depending on the winding progression image captured.

Method and device to manage a coiler apparatus associated with a distributor, in which there is at least an exit of the feeder of hot or cold semi-worked metal products, and with a reel, both being respectively moved with suitable controlled movement and rotation means, able to manage the coiling obtaining coils with desired characteristics.

Method and device (10) to manage a coiler apparatus (11) associated with a distributor (15), in which there is at least an exit of the feeder (21) of hot or cold semi-worked metal products, and with a reel (16), both being respectively moved with suitable controlled movement and rotation means, able to manage the coiling obtaining coils with desired characteristics.

A system for winding a rolled product includes a winder having a winding spool, a spool rotator, a distributor guiding positioning of the rolled product towards the spool at an instantaneous winding point, and a distributor translator. A control and command unit coordinates the rotator and the translator according to a predetermined winding program which is a function of predetermined reference operating parameters and of real time operating parameters. The detector includes a laser triangulation profilometer diametrically opposite to the distributor, and continuously detects the surface profile of the coil of rolled product at every added turn. A processing and calculation unit feedback adjusts translation speed of the distributor to minimize a difference between an actual operating parameter calculated based on the profile of the coil in formation detected by the profilometer and the same operating parameter calculated based on theoretical data related to a predetermined ideal coil winding.
