Davits Series ŻOW with WTR

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

Application

The auxiliary davit of series ŻOW, with manual slewing gear and hoisting 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 ŻOW with WTR scheme

Construction

Rated hoisting capacities Q of the davit series ŻOW are as follows:0,25; 0,63; 1,0; 1,61. Outreach values W in standard execution of davits are equal to: 1,0; 1,5; 2,0; 2,5; 3,0 and 3,5 m. on the special reguest, outreach of up to 6,5 m is also possible. Heights of davits H above the deck amount: 1,75; 2,25; 2,75; 3,25 and 3,75 m.

Davits are equiped with manual hoisting winch type WTR of "FAMA" Gniew make.

Slewing of davit is performed by means of mechanic transmission gear which is driven with two crank handles. Maximum force applied to one crank handle does not exceed 160 N. Maximum slewing angle of davit amounts to 360°. Slewing duration by an angle of 90° when cranking with speed 25 rpm, equals appropriately: 33 sec. for light duty modification, 82 sec for mean duty and 118 sec. for 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 ŻOW Q-W/H -WTR where:
Q - rated hoisting capacity [t];
W - outreach of davit [m];
H - height of davit [m];
WTR - denotation of the winch according to the list on the pages below.
