Davits Series ŻOWJe

Depending on the hoisting capacity and outreach, the davits are made in three structural modifications:
Davits Series Mean duty modification Davits Series
Heavy duty modification
Very heavy duty modification

Application

The auxiliary davit of series ŻOWJe, with electric drive for slewing gear and for rope winch, can be ope­rated at rated hoisting capacity under conditions of vessel's heel to 5° to either side and simultaneous trim up to 5°.

Davits series ŻOWJe scheme

Construction

The davits are made in the left-hand or right-hand variation, depending on the side from which the slewing gear is driven by means of the crank handle if in emergency.

Rated hoisting capacities Q of the davits are as follows: 0,25; 0,63; 1,0; 1,6; 2,0; 2,5; 3,2 and 4,0 t.
Outreach values W in standard execution of davits are equal to: 1,0; 1,5; 2,0; 2,5; 3,0; 3,5; 4,0; 4,5; 5,0; , 5,5 and 6m.
Heights of davits H above the deck amount: 1,75; 2,25; 2,75; 3,25 and 3,75 m.

Davits are equipped with electrically driven rope winch type WZP of "SEZAMOR sp. z o.o." make. Capacity of rope drum to 45 m of rope and allows for hoisting of cargo with speed about 10 m/min. onto height of about 45 m.
Slewing of davits is realised by means of mechanic transmission gear driven with electric motor. In emergency the davit may be slewed also with the crank handle. Slewing angle of davit is within range -180° to +180° with regard to the normal stowage position of davit. Slewing duration by an angle of 90° with electric drive equals appropriately: 15 sec. for mean duty modification, 20 sec. for heavy duty and 24 sec. for very heavy duty modification.


Standard delivery of davit includes:

The davits are constructed under survey of the Classification Society as required by the Customer and provided with Yard's Quality Control acceptance certificate.

Denotation of davit

Denotation of davit consists of davit name and symbol describing its technical parameters:

Radial davit ZOWJe Q - W - '35' (or '46') 'P' (or 'L') where:
Q - rated hoisting capacity [t];
W - outreach of davit [m];
H - height of davit [m];
'35' (or '46') - description of electric drive of rope winch
'35'-3x 380V/50 Hz;
'46' - 3 x 440 V/60 Hz;
'L' (or 'P') - designation of structural variation:
'P' - right-hand make;
'L'- left-hand make;
