Specifications – HWC 650 Electric

Item Value
Maximum chain size Short link 8mm (5/16")
Rated capacity at chainwheel 295Kg (650lb)
Chain speed 21 metre/min (69 ft/min)
Current at normal working load 12 Volt: 100 Amps
Current at stall 12 Volt: 500 Amps
Nett weight 17Kg (37.4lbs)
Chain Calibrated short link chain to I.S.O. 1836 or DIN 766
Standard build Chainwheel fitted to the port side; can be changed in the field to the opposite hand

Rated capacity and chain speed are based on maximum size calibrated short link chain; other sizes and/or optional motors affect capacity and speed. Designed to ABS rules for use with a chain stopper. The manual leaves the 24 Volt current values blank.

Location & Mounting

  • Allow a maximum of 600mm (24") between the chainpipe locker outlet and the chain piled up in the locker so kinks shake free.
  • Chain stopper between windlass and bow/chain roller, aligned so the chain passes through without being deflected and clear of the anchor stock.
  • Footswitches at least 250mm (10") from the rear of the windlass so the operator can tail from the warping drum; below-deck portion dry, breather holes clear, arrows showing direction.
  • Reversing solenoid in a dry area close to the windlass – never in the chain locker.
  • Breaker/isolator panel in a dry place within 1.8 metres (72") of cable length from the battery (mandatory for U.S.C.G.).
  • Deck must be reinforced for the breaking load of the chain; mounting pad perfectly flat (structural filler if needed). Standard units accommodate decks up to 100mm.
  • Leave room to swing the clutch lever clear of pulpit, lifelines and bulwark; for automatic operation the anchor must be self launching.

Electrical

  • Control circuits wired throughout in 1.5mm² (16 AWG) cable, with a manually resettable ignition-proof 3 amp fuse or breaker within one metre (40") of the breaker/isolator panel.
  • Main system: two-cable, ungrounded, fully insulated negative return; motor is isolated earth type.
  • Seal terminals after testing with CRC2043 "Plasti-Coat", CRC3013 "Soft Seal" or CRC2049 "Clear Urethane".
  • Builder: treat the finished installation with CRC 3097 "Long Life" and wrap in plastic film.

Usual controls: one footswitch, one roving two-button control with deck connector, one remote up/off/down toggle and one footswitch isolator.

Conductor length is the actual length between battery and windlass; sizes allow approximately 10% maximum voltage drop and assume insulation rated at least 90°C (USCG, ABYC and NMMA).

Under Power

  • Engage the cone clutches with the clutch lever (turn clockwise firmly), then remove the lever – never run the windlass with the lever in place.
  • Release the chain stopper pawl (jog up momentarily if needed) and lower or raise with the roving or remote control; it runs only while the button is held.
  • Motor over the anchor to reduce chain tension; jog in the last metre carefully and engage the stopper.
  • Never rely on the windlass to hold the anchor in its roller: secure it with a nylon line or a pin through roller and shank.

Manual & Warping Drum

  • Free-fall (power loss): stopper released, chainwheel pawl disengaged, back the clutch off two complete turns with the lever and regulate speed by tightening the clutch. Never let the chain run unrestricted.
  • Warping drum: engage stopper and chainwheel pawl, fully disengage the cone clutches, then work the drum from the footswitch with only as many turns as needed – allow slip under sudden load.

Annual & Gearbox

  • Annually: remove running gear, inspect, clean, regrease with lithium complex waterproof grease and reassemble. Chrome cleaner no more than once every 3 months.
  • Gearbox is sealed; approximately every two years remove gearbox and mainshaft, check output tube, drive key and spacer tube for corrosion and repack with anti-corrosive paste.
  • At the same time drain and refill with SAE 90 gear oil (e.g. Shell Omala 320, Castrol Alpha SP 320).

Tools & Lubricants

  • Long series Allen keys 5mm, 10mm, 2mm A.F.; 13mm A.F. ring/open spanner; 12mm blade screwdriver.
  • Grease: lithium complex base, NLG1 consistency No. 2 – never mix greases.
  • Anti-corrosion: CRC 3013 Soft Seal, Lanocote, Res-Q-Steel, Boeshield T9.
  • When ordering parts quote model, serial number, power supply, drawing reference, item and part number.
