Description
NDSC-R-23 – Liferaft davit has a manually driven, mechanical slewing arm and a manually driven winch with a single wire fall.

The lowering is based on gravity only, which allows full operation of the davit in “dead ship” conditions. The davit is safe, reliable, and requires minimal maintenance levels. The equipment pruduces low level of noise and provides good access for service and repair. 

The winch is fitted with a one-way clutch. If the power is lost, the brakes are activated automatically and davit motion is stoped. A centrifugal brake is located on the winch. The brake controls the speed of descent for the life raft(s). 

Conforms to the latest IMO/SOLAS requirements, LSA Code and European Council Directive 2014/90/EU on Marine Equipment (MED).

The system allows:
  • Manual slewing of the davit arm;
  • Gravity lowering of the fully loaded raft, controlled from within the raft or by the operator on the deck. Independent of any power supply;
  • High-speed manually retrieval of the empty hook. Low-speed retrieval of the full loaded raft (сonvenient for training/testing purpose);

Specifications
  • Davit system weight incl. winch (dry weight) - 1750 kg (approx.);
  • Safe working load - 2300 kg (max. 4.5 m slewing radius);

  • Operation temperature - from -20°C to +45°CManual hoisting;
  • Min. lowering speed - not less than that obtained from the formula S=0.4+(0.02H) and not exceed 1.3 m/s;
  • Manual hoisting - by manual hand-cranking;
  • Pivot bearing type - slewing bearing;
  • Wire sheaves - galvanized, equipped with ball bearings;
  • Installation - one deck welding point (reduced installation time);
