25、 equipment = 4.2.1 Trawl winches may be also fitted with auxiliary drums m and warping-ends: if these are fitted, their positions and characteristics shall be agreed between the purchaser and manufacturer. * * For the profile of warping-ends, see IS0 6482. 4.2.2 A spooling gear is to be fitted to th
26、e main drum in order to achieve uniform winding of the trawl rope, unless otherwise agreed between the purchaser and manufacturer. The auxiliary drums may also have spooling gears, if agreed between the purchaser and manufacturer. Provision shall be made for manual adjustment of any spooling gear fi
27、tted. Mechanical spooling gear (if fitted) shall be designed to operate against the drum load, at fleet angles up to 6O per side in horizontal and vertical planes. If the spooling gear is automatically driven, it shall be possible to disengage the spooling carriage. Subject to agreement be- tween th
28、e manufacturer and purchaser, the spooling gear shall be adaptable to wires of more than one diameter. 4.3 Control and measuring instruments 4.3.1 A trawl winch may have an instrument to measure the tension in the trawl rope, if agreed between the purchaser and manufacturer. The equipment shall be c
29、apable of measuring the tension while the rope is being paid-out, hauled-in and when trawling the fishing gear. The measurement of tension may be replaced by the measurement of torque at the drum whilst trawling, if agreed between the purchaser and manufac- turer. h is recommended, for winches great
30、er than nominal size 4 (see table 11, that the tension should be measured without contact of the measurement instruments (pick-up) with the trawl rope. 4.3.2 A trawl winch may have an instrument to measure the length of paid-out trawl rope, if agreed between the purchaser and manufacturer. Instrumen
31、t error shall not exceed 0,15 % of the trawl rope lengths. 4.3.3 A trawl winch may have instruments to measure the electrical and/or hydraulic values as agreed between the pur- chaser and manufacturer. 4.4 Signalling devices If agreed between the purchaser and manufacturer, a trawl winch may be fitt
32、ed with adequate signalling devices giving necessary information on ai the winch and its components being ready for oper- ation; bl Cl d) e) 4.5 4.5.1 which components of the winch are being operated; the engaging of clutches and/or drum brakes; failure of winch components; overloads and other dange
33、rous conditions, for example: - the trawl rope being down to the first layer on the drum while paying-out the fishing gear, - no release of the automatic brake, - allowable temperature of the electric motor wind- ings being exceeded, - slipping of the trawl drum while trawling the fishing gear. - ov
34、erloading of the spooling gear. Protection Overload protection of trawl winches shall be provided during hauling-in. It shall operate under overload not exceeding 1,5 times the value of drum load at the outermost layer of a trawl rope being fully wound onto the drum, unless a higher value is agreed
35、between the purchaser and manufacturer. A time interval protection device shall be fitted to overcome the transient overloads experienced in service. When the protec- tion device of one winch has operated, the second winch shall stop simultaneously. 3 STD-BSI BS EN IS0 bLLS-ENGL 1777 W lb24bb7 Ob007
36、88 345 EN IS0 6116 : 1996 4.5.2 Facilities for paying-out the rope under conditions of winch overload, while still trawling the fishing net, shall be pro- vided. For overloads up to 1.5 times the drum load at the outer- most layer, a multistep or continuous control of such device shall be possible.
37、If agreed between the purchaser and manufacturer, the device may operate automatically in which case means of switching off the device shall exist. Brake release shall be provided as well, if agreed between the purchaser and manufacturer. 4.5.3 Means protecting against paying-out of the whole length
38、 of a trawl rope from the main drum may be fitted. Not less than 20 windings of the trawl rope shall still remain wound onto the drum when such means have operated, unless other- wise agreed between the purchaser and manufacturer. 4.5.4 An emergency means of stopping the winch shall exist. It shall
39、be fitted at the winch position and at the remote control position, where such exists, and near the rope sheaves. For single-drum trawl winches, the single operation, where prac- ticable, shall cause the stopping of both winches. 4.5.5 Protection against overspeeding of the drive during paying-out s
40、hall be provided. 4.6 Control 4.6.1 Control position For each trawl winch, a local or remote control (or a combined remote and local control) shall be provided. For singledrum trawl winches, separate control of each trawl winch shall be provided. NOTE - Some national authorities require local contro
41、l on all trawl winches. 4.6.2 Direction of motion of operating devices The direction of motion of operating devices shall be such that the trawl rope or auxiliary rope is hauled-in by clockwise move- ment at a hand-wheel or crank handle or alternatively by move- ment of a hand-lever towards the oper
42、ator. The direction of operation of all control handles shall be clearly and permanently marked. 4.6.3 Remote control By agreement between the purchaser and manufacturer, the remote control shall provide operating conditions for simultaneous, common and synchronous operation on main. drums. 4.7 Brak
43、es and braking 4.7.1 Brakes Each winch shall have an automatic braking system which operates when bringing the operation device to zero, or to the braking position, and also when there is no power supply on the winch. Means shall exist for manual release of the brake. 4.7.2 Selective brake Each decl
44、utchable drum of the winch shall have its own selec- tive brake. The drum brake may also act as an automatic brake of normally closed type. The brake handle force during manual braking shall not exceed 0,25 kN. 4.7.3 Braking torque The total available braking torque shall be at least 1,5 times the d
45、esign torque. The brakes shall be adjustable, unless otherwise agreed between the purchaser and manufacturer. 4.7.4 Regenerative braking For regenerative braking, the rated load of the brakes shall be 0,5 times the design torque. In this case the paying-out speed of the trawl rope is related to the
46、number of revolutions of the driving motor and its characteristics. 4.7.5 Friction braking The drum brake of a trawl winch when paying-out the rope shall be capable of absorbing the power at a torque equal to 0,5 times the design torqueand at drum revolutions corresponding to twice the nominal speed
47、. The power shall be absorbed for two periods equal to rope length multiplied by winch speed separated by 15 min. Cooling of brakes to meet this specifica- tion is acceptable. The use of friction braking does not exclude the use of regenerative braking. 4.0 Ambient temperature The winches shall be d
48、esigned for satisfactory operation of their components at a temperature range within -25 OC to + 45 OC, when located on open decks, and within - 10 OC to + 45 OC when located in enclosed compartments; a different lower limit may however be agreed between the purchaser and manufacturer. 4.9 Material
49、stresses The winch manufacturer shall be responsible for determining the strength requirements of the component parts of the winch to withstand all the loads of each nominal size of trawl winch respectively. 4.10 Basic calculsrions 4.10.1 When a trawl winch with a trawl rope being wound on the outermost layer is loaded with the drum load, the allowed calculated stresses, based on simple elastic theory, of any part of the winch shall be not greater than 0.4 times the 0,2 % proof stress of the material but not more than 0,28 times the breaking strength of the material.
