SERIES LIFTING EQUIPMENT

1

Scope of application and purpose

Graphical symbols for control devices

This rule contains In the table hereafter symbols for the text-free marking of control devices for floor-operated lifting appliances.

2 Size

All symbols can be varied according to space available . However, the recognizability compared to theshown size should be taken into account.

3 Execution

The symbols should be attached in such a way that they will be permanent and cannot be wiped off.The shape of the background on which arrows and symbols are attached is indifferent .

4

Arrangement of the symbols on the control devices

The symbols can be arranged on or beside the control devices . The symbol No. 9 (signal) may alsobe arranged turned by 90° .

5

Instructions for application

In addition to the logically arranged arrows, control devices for opposed directions of movement mustbe distinguished by selection of inverted colours for the background and for the symbol .

For the switching of two different speeds there are two possibilities :

FEM9.941

a) Each speed is controlled by a different control device ; two arrows are used for the higher speed .

b) In the case of the so-called step switching, pressing the control device switches on first the slowand then the fast speed. The sign for this switching consists of two arrow heads arranged onebehind the other.

Crane travel movements away from and towards the operator are indicated by inclined arrows .

6

Instructions concerning the direction of crane and trolley movements

2nd edition (E)01 .1995

If the crane or the trolley Is provided with direction symbols, the following requirements must be met :

- The direction symbol must be clearly visible forthe the crane operator within the working area of thecrane and must be securely attached .

- The symbols on the crane and on the trolley must be analogue to those of the control device . Thesymbols indicated in the following table should be preferably used.

Short-time duty

FEM 9.683

Page 7

Under special conditions of duty (e.g . long travel of hook, the operating time may only be such that per-missible limit temperatures are not exceeded . In such cases, short-time duty is allowed instead of in-termittent duty. In this duty type, a lifting motor that has cooled down to the temperature of the cooling me-dium can be operated for a certain time with the load corresponding to the particular group of mecha-nisms . Minimum values for operating time of high speed and low speed windings' are given in table5.8.2.2.a for the various groups of mechanisms . No more than 10 starts may take place during this ope-rating time .

Mixed duty

Under mixed duty conditions, intermittent duty and sho_ rt-time duty alternate . The permissible limit tempe-ratures must not be exceeded .Table 5.8.2.2.a applies for lifting motors with one hoisting speed for intermittent duty . For creep speed lift-ing motors (separate motor) half the CDF values should be achieved with the same number of starts .For lifting motors with two speeds (pole-changing motors} the table values for both windings apply toge-ther for intermittent duty .

The following ratios are assumed:

Generally : high speed s 4-pole/ low speed >_ 6-pole

The number of starts specified in table 5.8.2.2.a refers to a uniform distribution aver an hour in which themotor reaches the rated speed. Other specifications are necessary for inching operation .

5.8.2 Motors for vertical motions5.8.2.1 Determination of required torquesFor a hoisting motor, the required powerto raise the maximum nominal Load (Pnmax) is defined in kW intaking account of the configuration of the gear transmission ratio and of the reeving according to the fol-lowing formula :

This results in the required torque to raise the maximum nominal load M Nmax in Nm:

P Nmax ' 9550 MNmax'

wheren : rotating speed of the motor in rpm

P Nmax

where :L : maximum nominal permissible lifting force in NV L :lifting speed in m/srl : efficiency of machinery

The manufacturer must ensure that the torque required far acceleration, for lifting the test load or to covervoltage and frequency tolerances are available .

The mechanical braking torque must be specified such that safe and reliable braking is ensured .If fitted, an electrical braking arrangement must be able to slow down the load in complete safety .

5 .8.2.2 Relationship between cyclic duration factor, number of cycles per hour and starts perhour

In such cases where no exact information is available, the values can be extracted from table 5.8.2.2b foroperating time and number of cycles for various types of mechanisms for vertical movements .

If necessary, the manufacturer can provide information in order to facilitate the selection o ¬ lifting motorsfor various crane types .

Minimum values for the number of starts per hour and also a relationship for the minimum values be-tween operating time, number of cycles per hour and starts per hour are given in table 5.8.2.2a .

Starting from the mean equivalent torque, the mean equivalent power Pmed inla :

The such defined motor can be selected in S3 duty if one single motion opernutes.

Should this not be the case, a special study has to be made.

For the motor selection, the mean equivalent power Pored should be correcteexceeds 1000 m and the ambient temperature if it deviates from 40° C oraccordance with 5.8.1 .5 .

Power correction as a function of cooling agent temperaturThe motor output powers given in the manufacturer's tables apply far dutywith !EC 34-1, namely for :

Rated voltageRated frequencyAmbient temperature 40° CSite altitudes up to 1000 m above sea level

At ambient temperatures above 40° C and/or altitudes higher than 1000values of the motors must be adjusted accordingly . Depending on the conwer, CDF or starting frequency are reduced, if the motors would otherwiseperature rise limit .

5.8.1.6Cyclic duration factor and number of cycles per hourThe operating time can be calculated for a drive in accordance with the fo

The operating time and the number of operations per hour of the motors asof the crane are an important basis for the thermal definition of the motorbetween the user and the manufacturer of the crane . In case it is not possia precise manner, refer to tables 5.8.2.2.b and 5.8.3.2 .b .

5.8.1 Criteria for motor selection (IEC 34-1)

required powers - the thermal power is also included in these required powers,maximum rated torque and maximum acceleration torque,cyclic duration factor,number of cycles/hour,type of control (type of braking),speed regulation, drive systemstype of power feed,degree of protection, (environment conditions),ambient temperature,altitude .

For the dimensioning of the motor, account has to be taken of :- the thermal calculation as per clause 5.8.1 .3.- the maximum required torque :

for hoisting mechanisms as per clause 5.8.2 .1 .for horizontal motions as per clause 5.8 .3 .1 .

The motor has to comply with both requirements .

If the required torque diagrams, in order to define the mean equivalent torque (as per 5.8.1 .3.1) are notavailable, these can be assessed with the help of tables 5.8.2.2 .b and 5.8.3 .2.b respectively .

5 .8 .1 .1 Remarks on the selection of motorsThe motors must be suitable for the operating conditions (criteria for motor selection 5.8 .1 ) and ensuresafe operation under related conditions .

In the event of electronic power control, the motors must be specified taking into account the cooling sys-tem and the speed range .

An external fan may be provided to increase the number of starts per hour and number of cycles perhour .

5.8.1 .2 Degree of protection (IEC34-5)5.8.1 .2 .1 Indoor applicationFor indoor application, under normal conditions, motors must comply with IP 23 at least .In dusty environment, motors must comply with ID 44 at least .

5.8.1 .2.2 Outdoor applicationFor outdoor application, motors must comply with IP 54 at least .In case of water condensation risk, care should be taken that the water condensation drain holes remainopen .

5.8,1 .2.3 Particular applicationMotors may comply with a lower degree of protection if they are appropriately protected, or protected byexternal means for their particular application .

5.8.1 .2.4 Explosive environmentsIn potentially explosive environments, motors must be explosion-proof as specified in EN 50014-50020 .

Attention :

Simultaneous intermittent duty or short-time defy are not permitted.

Short-time duty

FEM 9 .683 Page 11

Under special conditions of duty (e.g . long travel of hoak), the operating time may only be such that per-missible limit temperatures are not exceeded . In such cases, short-time duty is allowed instead of in-termittent duty. In this duty type, a lifting motor that has cooled down to the temperature of the cooling me-dium can be operated for a certain time with the load,

Minimum values for operating time of high speed and low speed windings are given in table 5.8 .3.2.a forthe various groups of mechanisms . No more than 10 starts may take place during this operating time'.

Mixed duty

Under mixed duty conditions, intermittent duty and short-time duty alternate . The permissible limit tempe-ratures must not be exceeded .

Table 5.$ .2.2.a applies for lifting rnotors with one hoisting speed for intermittent duty .For travel motors with two speeds, the values for both windings apply together .

The following ratios are assumed :

The number of starts specified in fable 5.8.3.2.a refers to a uniform distribution over an hour in which themotorreaches the rated speed. Other specifications are necessary for inching operation.

5.8.3.2 Relationship between cyclic duration factor, number of cycles per hour and startsper hour

In such cases where no exact information is available, the values can be extracted from table 5 .8.3 .2.bfor cyclic duration factor and number of cycles for various types of mechanisms for horizontal mo-vements . If necessary, the manufacturer can provide information in order to facilitate the selection oftravel motors for various crane types .

Minimum values for the number of starts per hour and also a relationship far the minimum values be-tween cyclic duration factor, number of cycles per hour and starts per hour are given in table 5.8 .3.2.a .

In practical operation, a lower number of cycles can also occur in the lower groups at the given numberof starts and a higher number in the higher groups, for instance when operation is automated . If travelmotors are used in the short-time made, e.g . where the travel distances are long, there must be no morethan 10 starts . Minimum values for the operating time for the various groups of mechanisms are given intable 5.8.3 .2.a .
