Hydrauvision Rental has introduced an advanced winch spooling device, the HydrauTool Spooler 25/50. It is used to evenly wind a winch cable across the full width of a drum. Roland Picavet, commercial manager, explained: `Considering the fact that the pulling force of our rental winches differ each time, the mechanical winding method – by means of a fixed grooved spindle construction, whereby the cable is wound by means of a parallel movement from left to right and vice versa, is not suitable, since this is not a flexible solution for the handling of different wire diameters. That is why we developed this new winch spooling device.’
And not only the cable diameters differ, the pulling force varies greatly as well: Hydrauvision Rental has a series of winches, from several tons of pulling force up to the 80-ton versions. An advanced winding system was therefore needed. Starting points were a flat drum, variable cable diameters, and variable pulling forces, in combination with the demand for winch positions with a large fleet angle. The latter because of the lack of space that is often the case, for example on deck.
Standardised connections
The new spooling device, which was developed by parent company Hydrauvision Systems, is electronically controlled. According to DIN standards, the fleet angle may not exceed 2 degrees. This was also practice-inspired. The guidance consists of a guiding cell comprising two rollers and a sensor. This electronic sensor measures the angle and ensures that the cell moves more or less according to the desired angle. The spindle is in-between the two rollers and is hydraulically driven. The HydrauTool Spooler 25/50 was specifically made for the Hydrauvision Rental HydrauWinch 25 CT and HydrauWinch 50 CT winches with the same footprint. In other words, the connections are standardised. The spooler frame is a crash frame, i.e. a protective frame and approved according to DNV2.7-3 (lifting in offshore). Picavet: ‘The spooling devices can also be connected to `other` winches, on the condition that the size will approximately match. Normally, a maximum angle of 30 degrees is used with the full pulling force of a 25-ton winch; but, depending on various factors, an angle of 17 degrees can be used for winches with a pulling force of up to 50 ton.’ In short, the new spooling device is multifunctional.
