14、serving the requirements of the standard, they should at the same time ensure compliance with such statutory requirements, rules and regulations as may be applicable to the individual ships concerned. 1 Scope This British Standard specifies the requirements for the design, construction, safety, perf
15、ormance and acceptance testing of lightly powered and unpowered topping winches. The standard does not include requirements for the prime mover used to operate the winch. 2 Definitions For the purposes of this British Standard, the terms and their definitions given in BS MA 30 apply. A term particul
16、arly applicable to this British Standard is defined as follows: 2.1 nominal size the nominal size of a topping winch corresponds to the nominal load, in tonnes, at its design speed NOTE 1The range of nominal sizes covered by this standard is listed in Table 1, column 1; associated hauling loads are
17、listed in Table 1, column 3. NOTE 2The nominal sizes of topping winches in Table 1 have been selected from the R5 series of preferred numbers (see BS 2045). 3 Design and construction 3.1 Handing of winches 3.1.1 Handling of topping winches (lightly powered). These may be designed as left or right ha
18、nd winches. A winch is termed a right-hand winch in relation to an observer situated on the side of the motor, power supply or controller, having the topping rope hauling in the direction shown in Figure 1, and the prime mover on the right-hand side of the drum. Similarly, a winch is termed a left-h
19、and winch when the prime mover is situated on the left-hand side of the drum (see Figure 1). 3.1.2 Handing of topping winches (unpowered). These may be designed as left or right-hand winches, supplied with a division flange to separate the messenger rope from the topping rope. A winch is termed a ri
20、ght-hand winch in relation to an observer (see Figure 2), having the messenger rope on the right and the topping rope on the left of the drum. Similarly, a winch is termed a left-hand winch when the messenger rope is on the left and the topping rope on the right of the drum. Left-hand winchRight-han

The manufacturer of
22、the winch shall be responsible for determining the strength requirements of the component parts of the winch to withstand the hauling load and holding load of the respective nominal sizes of the winches, specified in Table 1. 3.2.2 Material stresses (unpowered). The manufacturer of the winch shall b
23、e responsible for determining the strength requirements of the component parts of the winch to withstand the hauling load and holding load specified in Table 1 for nominal size 2.5 only. 3.3 Drum size 3.3.1 The drum shall be capable of reeling the whole of the topping rope that is required in servic
24、e. The purchaser shall state on the order the capacity required. 3.3.2 The drum length shall be such that the topping rope can be fully accommodated in not more than three layers, the complete length of the rope being evenly reeled. 3.3.3 Drum diameter 3.3.3.1 Drum diameter (lightly powered). The dr
25、um diameter shall be not less than 14 times the topping rope diameter. The minimum drum diameters are listed in Table 1, column 7. 3.3.3.2 Drum diameter (unpowered). The drum diameter shall be 400 mm. 3.3.4 The flange height shall be such that it will project at least 2.5 rope diameters beyond the o
26、utermost layer when the topping rope is fully and evenly reeled on the drum. 3.4 Drum locking device. Topping winches shall be provided with a means for locking the drum in any position and it shall be capable of resisting a torque not less than 1.5 times the maximum holding torque. The locking devi
27、ce shall be interlocked so that the winch will not start in the lowering direction until the locking device has been disengaged. 3.5 Control brake system 3.5.1 Control brake system (lightly powered) 3.5.1.1 A system of braking shall be automatically applied to the prime mover when the control handle
28、 is in the “off” position, or when the power supply is cut off. 3.5.1.2 The control brake system shall be capable of effectively arresting and holding a load at least equal to the holding load listed in Table 1, column 4. 3.6 Emergency stop 3.6.1 Emergency stop (lightly powered). The winch shall be
29、fitted with a quick acting local emergency stop mechanism which when operated removes power from the winch and applies the control brake system. 3.6.2 The emergency stop shall be located in a clearly marked and accessible position close to a remotely controlled winch and adjacent to a manually contr
30、olled winch. 3.7 Speed control (lightly powered) 3.7.1 The maximum light line speed shall be 0.41 m/s. Higher speeds may be provided only if specified by the purchaser. 3.7.2 The control system shall be such that it is possible to move the controls from the full veer position to the full haul positi
31、on in less than two seconds, or vice versa. The speed at which the controls are manipulated shall not have an adverse effect on either the winch machinery or the safety of the operator. Winch response times shall be supplied by the manufacturer to the purchaser on request. Left-hand winchRight-hand

33、e purchaser and manufacturer. 3.8 Design rope 3.8.1 This standard is based on the use of 6 24 steel wire rope with fibre core as specified in BS 365. The diameters of this wire rope associated with the holding loads are listed in Table 1, column 6. 3.8.2 The rope size shall be such that its minimum
34、breaking strength (kN) is not less than 5 times the holding load, allowing for the number of parts of rope in the tackle. The minimum breaking strengths listed in Table 1, column 5 are based on the use of two-part tackle. If it is a requirement that a winch shall operate with a rope other than that
35、given in 3.8.1, it shall be stated on the order. 3.8.3 The ends of the topping or messenger ropes shall be efficiently secured to the rope drum in a manner, other than by a fibre rope tail, that will not result in damage to the ropes at the connection or in succeeding layers. 3.9 Control methods and
36、 movements 3.9.1 Methods of control. The methods of control shall be either manual or remote. A combination of the tests may be used to describe control methods, e.g. manual/remote. Manual control means that the topping winch is controlled solely by an operator. Remote control means that the control
37、 position is at a distance from the topping winch being controlled. The control position may be fixed or portable. 3.9.2 Power sources. Lightly powered topping winches shall be designed for operation, powered by either electric, hydraulic or steam drive, designated E for electric, H for hydraulic or
38、 S for steam. 3.9.3 Direction of motion of the operating devices 3.9.3.1 The direction of rotation of a topping winch drum shall be clearly marked in relation to the movement of the control. 3.9.3.2 All control handles, handwheels and push buttons shall be clearly and permanently marked with their p
39、urpose and mode of operation, unless this is obvious from their design and position. 3.9.3.3 The maximum travel of a control handle shall not exceed 600 mm in any one direction or 300 mm each side of a central position. 3.9.4 Foot pedals. The maximum travel of the pedal shall not exceed 250 mm. Foot
40、 pedal operated brakes shall be applied when the pedal is depressed and released when raised.

When fitted, g
41、ear levers shall be positively located in any gear position or neutral by click stops or other similar means. 3.9.6 Hand levers. Brakes applied by hand shall require a force not exceeding 160 N in order to exert the braking torque of 25 % in excess of the driving torque required to maintain the hold
