VERTICAL WINDLASSES – VR/VRC Vertical windlass models have a main vertical shaft and horizontal gypsy,and are available in two configurations. VRC has a gypsy and independent
capstan, whilst the VR has gypsy and low profile top only. The low profile
VR is available on models VR4000 through to VR 11000.The vertical configuration allows for single and twin installations with theadvantage of installing the
windlasses in various positions. This facilitates the
positioning of hawser pipes, chain pipes and anchors. In some cases it maybe preferable to install windlasses closer to the centre line or further apart.Our new generation Integral Base VR/VRC 4500, 6000, 8000, 11000designs incorporate extended deck plates for the brake band location and
integral chain pipe. The windlass and chain pipe are supplied as a completeassembly on one single base, either as single units or in mirror image.Muir vertical windlass design innovation enables disassembly of the runninggear above the deck plate and removal of the drive gear below deck
leaving the deck plate and chain pipe/roller intact.All vertical windlass bases accommodate a self-aligning gearbox adaptorthat reduces installation time and allows the gearbox and motor to beinstalled directly onto the shaft in any radial position. This alleviates
distortion between the deck plate and gearbox flange and a sealed shaft
protects the transmission below deck.Vertical windlasses require less deck space than a
horizontal windlass andvertical capstans have operational advantages for mooring purposes due tothe radial scope of the lead for
mooring lines. For servicing and lubrication
all running gear is readily accessible. Planetary drives are available on most vertical models with AC andHydraulic brake motors fitted. Helical right angle drives are available forspecial applications.Hydraulic drives are fitted with counter balance valves to prevent runback.Heavy-duty dog clutch drives on larger models ensure positive drive at all
times, hand wheels and brake bands to chain gypsies provide infinite controlofbraking.Standard units with circular base plate have installation flexibility of rotatingbrake band and hand wheel in any position.Up to 180°chain wrap on vertical designs ensures optimum utilisation of thechain gypsy pockets.Independent operation of the capstan and gypsy is achieved by declutchingthe capstan.The full range is available with an extended capstan shaft for splitpositioning of the gypsy below deck and capstan above deck for mooring
and line hauling purposes. VRC13000
