TECHNICAL INFORMATION Muir has adopted the corporate policy of manufacturing and selling products which have the recognised standard of qualitythat satisfies customers throughout the effective life span of the product. It is therefore an essential requirement of this stipulatedpolicy for Muir to produce and supply its customers with products which are suitable for their intended purpose, and which
are in conformity with the relevant and agreed specification or contract.The procedures outlined in our ISO9001 quality assurance manual describe how the quality system is designed to ensure thatcustomer requirements are recognised and that consistent control of these requirements is established, implemented and
maintained. Strict adherence to the policy stated above is a requirement of every aspect at Muir.AutoCAD drawings are available as digital files.
Standard builds are bronze with chromed finish and peened capstans. Vertical and horizontal builds can be supplied inpolished bronze, chrome bronze, stainless steel, alloy or cast steel or a combination to suit the designers and ownersrequirements.Chrome plating with a minimum of 35 microns is used in production. All running gear is bronze, aluminium bronze or 316 or Duplex stainless steel and the main drive shaft, brake spindle,handwheels and fastenings are stainless steel.Motor drives and gears below deck are finished in white gloss.Heavy-duty brake design on some models may not require use of
chain stoppers or where distance between spurling pipe andgypsy is tight.On placing an order we require a chain sample, including joining links and kenter
shackles (if they are to be accommodated),so they can be matched to the chain gypsy and ensure correct fit.Thermistors are available to protect AC motors from condensation, and should be connected to the circuit trip relays toprovide overload protection.Chain Gypsies are available to suit ISO, DIN 766 and Studlink
marine chains.
Custom Designed
Windlasses for specialised installations can be supplied on request. IMPORTANT:KW Power requirements: Power shown for windlasses meets or exceeds classification rules requirements. Power may beincreased if required for special applications.On both windlasses and capstans it is advisable to maximise KW power on AC/two-speed drives to optimise functionality,and to prevent the circuit breaker tripping.KW power requirements - may vary between planetary worm and gear drives. Starting loads: the design of the preferred starting system is important, and it should be noted that the vessels generatingcapacity and requirements should be able to start the windlasses under high load. Mooring Capstans: Selection and sizing needs to consider high profile, large or heavy displacement craft and high windconditions to be encountered while mooring. Model Numbers: Product model numbers are not necessarily indicative of the
marine lift capacity, rating or working load. CLASSIFICATION PERFORMANCE AND APPROVAL: Classification requires a minimum speed of 9 metres/minute and Muir designs have optional two-speed systems in hydraulicor AC drives up to 18metres/minute. Muir will build to specific classification society requirements including ABS, Lloyds, DNV, NKK, BV, K.R and CCS. All Muirequipment meets international standards including MCA and USL codes and CE Requirements for electrical components. GLOSSARY OF TERMSWindlass: A vertical or horizontal mechanical apparatus manually, electrically or hydraulically operated for pulling or hoistinganchor and cable (chain or synthetic rope), incorporating a circular chain wheel or gypsy normally with a minimum of fivepockets into which
anchor chain links fit snugly. Rating: Is the maximum pull, load, that is applied to the windlass. Working Load: As stated or recommended by the relevant classification society. Otherwise typically the lift is usually up to25% of the rating. Gypsy: Chain wheel, Wild Cat.
