2. Construction and main materials
The deck crane is to be designed with the construction and main materials in accordance with the Classification Rule and JIS standards, and to be manufactured in accordance with the approved general assembly drawing.
2-1 Construction
(1) Hoisting and luffing winches
These winch are accommodated in the crane housing with the state of the luffing winch installed over the hoisting winch.
Hoisting winch drum can be driven by the hydraulic motors through one (1) stage reduction gear.
Luffing winch drum can be driven by the hydraulic motor through planetary reduction gear. The reduction gear is in the enclosed casing and lubricated by oi I bathing.
Each winch has spherical roller bearing to improve efficiency.
In addition, as the winch drum is grooved, the wire rope can be wound regularly on the drum.
The hoisting winch braking system has two (2) systems, one is hydraulic blocking system (counter balance valve) and the other is hydraulic band braking system.
The band brake is fitted to drum flange, and can be applied by the spring force and released by hydraulic pressure.
The material of the brake lining is of asbestos-free.
Hoisting winch is provided with a pinch roller.
The luffing winch braking system has two (2) systems, one is hydraulic blocking system (counter balance valve) and the other is hydraulic disc braking system.
(2) Slewing device
This crane is installed on the turn table bearing which is subject to the overturning moment and thrusting load at the same time.
The inner race of the turn table bearing is provided with the internal gears and is fixed to the hull post by bolting. Also the outer race is fixed to the crane base by bolting.
The slewing device consists of the hydraulic motor, planetary reduction gear, pinion, hydraulic disc brake and the pinion is engaged with the internal gear of the turn table bearing. The reduction gear is in the enclosed casing and lubricated by oil bathing.
The braking system has two (2) systems, one is hydraulic blocking system (counter balance valve) and the other is hydraulic disc braking system.
The hydraulic disc brake stops the slewing device when the power system is out of operation.
(3) Crane body
The body is of a box type of welded steel and the base is fixed to the turn table bearing by bolting.
(4) Jib
The jib is manufactured of welded steel and has sufficient strength and rigidity for external force.
(5) Steel wire rope
The steel wire rope for hoisting is a non-self-rotating rope and that for luffing is of JIS No. 18.
These ropes are galvanized.
■Hoisting rope (non-rotating rope)
U4 x SeS (39) (SHINKO WIRE CO., LTD.) Galvanized, Z-lay Sheathing Dead Eye Thimble-36
Luffing rope (JIS No.18)
6 x Fi (29) .class C , IWRC .Galvanized , Z-lay
(6) Operator’s cabin
The cabin is completed with heat and sound insulation on the wall.
Two operating handles are arranged in the cabin and each handle in connected to each hydraulic control valves in machine room.
Hoisting handle is easily operated by a right hand, luffing and slewing handle is done by a left hand.
Luffing and slewing handle is adopted the universal controller to operate both action of luffing and slewing.
To raise the efficiency of cargo handling, the three motion at the same time can be carried out with light load.
The noise level in the operator’s cabin is less than 85dB(A).
The hydraulic system for hoisting, luffing and slewing is composed of fixed displacement hydraulic oil pumps, fixed displacement oil motors, control valves, counter balance valves and other accessories.
Of course, the pressure relief valve is fitted in each circuit to prevent the line from over pressure.
The pressure oil delivered from each oil pump driven by an electric motor is regulated by the control valve and is supplied to each oil motor.
So, the speed of each motion can be controlled gradually by controlling the control valve.
The hydraulic system has two (2) circuits, one is for hoisting and the
other is for slewing and luffing which line is connected in series.
The return lines of each circuit are connected together.
The oil flows together in return line and flows through air cooled oil
cooler which is automatically controlled by a thermo switch and in a 10 micron-oil filter and then, oil gets back to each suction chamber of oi I pumps.
Furthermore, a head pipe with head tank connected to the return line gives a little positive pressure and supplies oil in the circuit for developing the sucking performance of oi I pumps.
2-2 Electric equipment
(1) General
The main power electric source is connected to the no-fuse-breaker (N. F. B) in the starter panel located in the machine room through cable from slipring of the collector.
The aux. electric source for lighting and heating apparatus is led to the control stand in the cab through cable from the slipring of the col lector.
The necessary devices except main switch for operating the deck crane are functionally arranged in the cab.
The switches of space heater for main motor, control stand and starter panel is fitted on the control stand.
(2) Electric source
The following voltage are to be used for the deck crane.
AC440V, 60Hz, 30......For main circuit of the electric motor
AC440V, 60Hz, 10......For main contact coil of the electric motor
for the hydraulic pump & oil cooler
AC110V, 60Hz, 10......For control circuit of the solenoid valve
DC24V....................For other control circuit
AC220V, 60Hz, 10......For lighting and heating circuit
Ship supply source.......AC440V, 60Hz, 30, 225A
AC220V, 60Hz, 10. 30A
The supply line provided from the ship is connected to the brush of the collector beneath the floor center of the machine room.
(3) Main motor for hydraulic oil pump
The electric motor for the hydraulic pump is to be started by the method (three contactor method) and the starting current is to be decreased in one-third of directly starting.
(a) Three phase induction motor for marine use
(b) Totally enclosed with outside fan squirrel cage rotor equipped with
ball bearings
(c) Insulation class F
(d) With space heater & thermal switch
(e) I EC numbers of protection IP55
(4) Motor for oil cooler
The electric motor for oil cooling fan can be automatically operated by the oil temperature while the electric motor for the hydraulic pump is operated. The electro-magnetic switch is actuated by the thermostat for detecting oil temperature which is inserted in the hydraulic piping and causes the motor to operate.
(a) Three phase induction motor for marine use
(b) Totally enclosed with outside fan squirrel cage rotor equipped with
shield balI bearings
(c) Insulation class F
(d) Direct start
(e) IEC numbers of protection IP55
(5) Starter panel
Use for starting circuit of main motor for hydraulic oil pump & motor for oil cooler and other.

Installed in machine room of deck crane.
(6) Control stand for single crane
Control circuit including control switch, indicating lamp and control relays is built in this control stand.
Constructed by steel plate and drip-proof type (IP22).
Installed in cabin of deck crane.
(7) Electric cable
All cables installed throughout the deck crane shall be of Japanese Industrial Standard (JIS) and of 0. 6/1kV or 250V grade insulation to meet the voltage to which they are subjected.
The conductors supplying single load, in general, shall have continuous current carrying capacity equal to 100% of the rating of the connected load.
(8) Slipring
