2.1.1 Intended use - Foreseen use - Designated use
The electric wire rope hoist is a machine generally used to lift vertically in the air a load by means of a hook or
handling accessories suitable for the purpose.
When the hoist is coupled with a trolley, which runs at a height on one or two girders, it is capable of ensuring the
integrated handling of lifting and horizontal movements of the load.
All the lifting movements (of ascent or descent) or travelling (right or left) dmust be activated electrically and can
be controlled with a push- button panel or with a remote control system.
The electric wire rope hoist and the related trolleys, installed at a height, can be fitted with monorails or constitute
the lifting unit of other machines in which they have been incorporated, such as: overhead travelling crane, gantry
crane, jib crane, etc. both in single and double girder versions.
The electric wire rope hoist, positioned at a height or at ground-level, subject to appropriate safety checks and any
necessary forms of protection (see paragraph 3.4) can moreover be used in different configurations in a fixed position.
2.1.2 The range
The range of DRH electric wire rope hoists series is produced in:
• 4 base series, DRH1 - 2 - 3 - 4, for capacities from 800 to 50.000 kg, in the FEM (ISO) service units - 1Bm (M3) -
1Am (M4) - 2m (M5) - 3m (M6).
• At a lifting speed carried out with a 4 -pole motor:
• 4 or 6 m/min for 4-fall wire rope hoists
• 8 or 12 m/min for 2-fall wire rope hoists
• 2,7 m/min for 6-fall wire rope hoists
• 2 m/min for 8-fall wire rope hoists.
• At two lifting speeds, with a 1/3 ratio, carried out with a 4/12 - pole motor:
• 4/1, 3 or 6/2 m/min for 4-fall wire rope hoists
• 8/2, 6 or 12/4 m/min for 2-fall wire rope hoists
• 2,7/0,9 m/min for 6-fall wire rope hoists
• 2/0,7 m/min for 8-fall wire rope hoists.
• 5 standard versions with short drum (C), normal drum (N), long drum (L) and extra long drum (X1) and (X2) for
hook runs from 4 to 58 m.
The DRH electric wire rope hoists are available in the following standard configurations:
• In fixed execution: (fig. 1)
Basic universal configuration, with fixing eye bolts which allow the hoist to be set down in any version, or to be
adapted to suspended execution.
• With electric trolley, single girder, type DST/N/S: (fig. 2)
The DRH hoist is supplied with suspended execution on the normal trolley and articulated for curvilinear girders,
running on a single girder by electric drive.
• With electric trolley, single girder, type DST/R: (fig. 3)
In order to exploit the hook’s run the DRH hoist is supplied set down in execution on the reduced headroom trolley,
running on a single girder by electric drive.
• With electric trolley, double girder, type DRT: (fig. 4)
The DRH hoist can be assembled either in set down or suspended execution on the trolley, which runs along the
two girders by electric drive.
The trolley in the double girder configuration maximises the hook’s run of the hoist.
2. - DESCRIPTION OF THE MACHINE AND TECHNICAL INFORMATION
2.1 The electric wire rope hoist and related trolleys
Technical data and characteristics are explained in paragraph 2.2
The conception and structure:
• The DRH electric wire rope hoists and related electric trolleys are produced according to the conception of modu-
lar components which, assembled together in relation to commercial needs, as well as the standard versions
always available in the warehouse, allow various normalized and special executions to be carried out rapidly and
economically.
• The basic components, motor, reducer and drum, thanks to the extreme compactness of the reducer group are
assembled together in coaxial line, to ensure maximum use of the hook path and minimum lateral encumbrance
of the hoist body.

2.1.1 Intended use - Foreseen use - Designated use
The electric wire rope hoist is a machine generally used to lift vertically in the air a load by means of a hook or
handling accessories suitable for the purpose.
When the hoist is coupled with a trolley, which runs at a height on one or two girders, it is capable of ensuring the
integrated handling of lifting and horizontal movements of the load.
All the lifting movements (of ascent or descent) or travelling (right or left) dmust be activated electrically and can
be controlled with a push- button panel or with a remote control system.
The electric wire rope hoist and the related trolleys, installed at a height, can be fitted with monorails or constitute
the lifting unit of other machines in which they have been incorporated, such as: overhead travelling crane, gantry
crane, jib crane, etc. both in single and double girder versions.
The electric wire rope hoist, positioned at a height or at ground-level, subject to appropriate safety checks and any
necessary forms of protection (see paragraph 3.4) can moreover be used in different configurations in a fixed position.
2.1.2 The range
The range of DRH electric wire rope hoists series is produced in:
• 4 base series, DRH1 - 2 - 3 - 4, for capacities from 800 to 50.000 kg, in the FEM (ISO) service units - 1Bm (M3) -
1Am (M4) - 2m (M5) - 3m (M6).
• At a lifting speed carried out with a 4 -pole motor:
• 4 or 6 m/min for 4-fall wire rope hoists
• 8 or 12 m/min for 2-fall wire rope hoists
• 2,7 m/min for 6-fall wire rope hoists
• 2 m/min for 8-fall wire rope hoists.
• At two lifting speeds, with a 1/3 ratio, carried out with a 4/12 - pole motor:
• 4/1, 3 or 6/2 m/min for 4-fall wire rope hoists
• 8/2, 6 or 12/4 m/min for 2-fall wire rope hoists
• 2,7/0,9 m/min for 6-fall wire rope hoists
• 2/0,7 m/min for 8-fall wire rope hoists.
• 5 standard versions with short drum (C), normal drum (N), long drum (L) and extra long drum (X1) and (X2) for
hook runs from 4 to 58 m.
The DRH electric wire rope hoists are available in the following standard configurations:
• In fixed execution: (fig. 1)
Basic universal configuration, with fixing eye bolts which allow the hoist to be set down in any version, or to be
adapted to suspended execution.
• With electric trolley, single girder, type DST/N/S: (fig. 2)
The DRH hoist is supplied with suspended execution on the normal trolley and articulated for curvilinear girders,
running on a single girder by electric drive.
• With electric trolley, single girder, type DST/R: (fig. 3)
In order to exploit the hook’s run the DRH hoist is supplied set down in execution on the reduced headroom trolley,
running on a single girder by electric drive.
• With electric trolley, double girder, type DRT: (fig. 4)
The DRH hoist can be assembled either in set down or suspended execution on the trolley, which runs along the
two girders by electric drive.
The trolley in the double girder configuration maximises the hook’s run of the hoist.
2. - DESCRIPTION OF THE MACHINE AND TECHNICAL INFORMATION
2.1 The electric wire rope hoist and related trolleys
Technical data and characteristics are explained in paragraph 2.2
The conception and structure:
• The DRH electric wire rope hoists and related electric trolleys are produced according to the conception of modu-
lar components which, assembled together in relation to commercial needs, as well as the standard versions
always available in the warehouse, allow various normalized and special executions to be carried out rapidly and
economically.
• The basic components, motor, reducer and drum, thanks to the extreme compactness of the reducer group are
assembled together in coaxial line, to ensure maximum use of the hook path and minimum lateral encumbrance
of the hoist body.
The components are connected by high-resistance bolted couplings which can be inspected and fitted with self-
locking safety nuts to protect against unscrewing.
• The drum, on the equipment side, or from the side opposite the motoreducer, can be used for connection
with cycle counters, selectors, screw limit switches, encoders, safety brakes, etc. Moreover the drum,
being perfectly symmetrical, in special execution with right and left threading, allows the assembly of two
motoreducer groups which permit doubling of the lifting speed while keeping the lifting capacity and
vertical fall axis unvaried which, free from eccentricity, makes it particularly suitable for executions with
high hook runs.
• The structure uses the most advanced technology based on production processes of high industrialization and
allows the realization, by economies of scale, of totally reliable and technically innovative machines. A high level
of quality is guaranteed and checked by the company quality control system according to standard UNI EN ISO
9001:2008.

2.2.6 Criteria and condition of use
• Correctly determine the operating limits of the hoist in order to ensure the correct functioning and the complete
correspondence to the operating systems of the work for which it is intended.
• The FEM 9.511 rule allows the classification of hoists according to the conditions of use.
• The necessary parameters to determine the limits of use for electric wire rope hoists are the following:
1) Actual lifting capacity; 2) Stress level; 3) Average duration of daily use.
1) Actual lifting capacity
• This is determined by the heaviest load to be lifted.
2) Stress level
•
The stress level is determined considering the actual entity of the loads lifted and it is ascribable to one of the
four spectrums of load shown below which determine the type of service.
The nominal lifting capacity of the hoist must be ≥ the actual lifting capacity Lifting capacity = kg
3) Average duration of daily use - Tm=hours
• For lifting operations the average duration of use is calculated in the following way:
Hoists which rarely lift maxi-
mum loads but mainly redu-
ced loads
Hoists which lift approximately
the same number of maximum,
medium and reduced loads
Hoists which frequently lift
the maximum load but
normally medium loads
Hoists which regularly lift
loads approximately equal
to the maximum load
It is the average of the actual

Classification and limit of use of the electromechanisms of lifting equipments
Example:
Capacity = 6300 kg Level of stress = 2) Medium Load Actual hook run (AHR) =2,5 m N° of cycles per hour (C/h) =8
Daily running time (Rt) =8 h Lifting speed (S) =4 m/min (4/1 rope falls) N° of working days per year = D/y 220
1) Calculation of the average daily running time:
Tm (hour) = (AHR x C/h x Rt) / (30 x S) = (2,5 x 8 x 8) / (30 x 4) = 1,33 h
In the table in section 2.2.7, in relation to the Capacity (6300 kg), at a Medium level of stress (2) and at an average daily running time (Tm = 1,33h)
it is possible to determine the rope hoist, with 4/1 falls of rope, which is:
Service Group FEM 1Am – Type DRH 24L1•M
2) Check of the time of life:
Hours of running 10 years Tm x D/y x 10 years = 1,33 x 220 x 10 = 2933 (hours) < of the 3200 (maximum hours possible) ok
N° of cycle of work in 10 years C/h x Rt x D/y x 10 years = 8 x 8 x 220 x 10 = 140800 (cycles) < of the 250000 (maximum hours possible)

• The designation of the group of utilization of the wire rope hoist is shown on the label plate on the
hoist (see paragraph3.5.3 - List of labelling plates)
• DONATI SOLLEVAMENTI S.r.l. guarantees the safe and lasting utilization only if the DRH electric
wire rope hoist is used according to the corresponding parameters for the group of utilization
foreseen.
Choice criteria and condition of use:
• According to the type use, that determine the stress level and the average duration of daily use, for lifting and/
or travelling, using the following table the identification group of the related mechanism are classifiled and then,
according to the lifting capacity, the type of hoist is determined
.
• Once the type of hoist is identified, it’s important to check the related life time in terms of hours of service and of
the total number of cycles in 10 years of operations.
Use in base of the stress level
(type of service)
Intermittent use
according to
FEM 9.683/95

use
Time of life of the lifting equipment:
• The time of life of the lifting equipment is determined from the stress level, the real running hours of each
mechanism and the number of cycles of the complete machine. The running hours and number of cycles, in
relation to the FEM/ISO of the lifting equipment selected are forecast to allow a safe life period of 10 years.
• After 10 years the lifting equipment could have finished the life of service in relation to the related group of servi-
ce. For this reason at the due time of 10 years the equipment SHOULD NOT be put any more in service without
an inspection by DONATI SOLLEVAMENTI S.r.l. expert technicians in order to check if the equipment has still some
remaining working life, so able to work in safe condition for a further period, the equipment has to be subject to
a deep technical control of all the parts.

Classification and limit of use of the electromechanisms of lifting equipments
Example:
Capacity = 6300 kg Level of stress = 2) Medium Load Actual hook run (AHR) =2,5 m N° of cycles per hour (C/h) =8
Daily running time (Rt) =8 h Lifting speed (S) =4 m/min (4/1 rope falls) N° of working days per year = D/y 220
1) Calculation of the average daily running time:
Tm (hour) = (AHR x C/h x Rt) / (30 x S) = (2,5 x 8 x 8) / (30 x 4) = 1,33 h
In the table in section 2.2.7, in relation to the Capacity (6300 kg), at a Medium level of stress (2) and at an average daily running time (Tm = 1,33h)
it is possible to determine the rope hoist, with 4/1 falls of rope, which is:
Service Group FEM 1Am – Type DRH 24L1•M
2) Check of the time of life:
Hours of running 10 years Tm x D/y x 10 years = 1,33 x 220 x 10 = 2933 (hours) < of the 3200 (maximum hours possible) ok
N° of cycle of work in 10 years C/h x Rt x D/y x 10 years = 8 x 8 x 220 x 10 = 140800 (cycles) < of the 250000 (maximum hours possible)
ok
• The designation of the group of utilization of the wire rope hoist is shown on the label plate on the
hoist (see paragraph3.5.3 - List of labelling plates)
• DONATI SOLLEVAMENTI S.r.l. guarantees the safe and lasting utilization only if the DRH electric
wire rope hoist is used according to the corresponding parameters for the group of utilization
foreseen.
Choice criteria and condition of use:
• According to the type use, that determine the stress level and the average duration of daily use, for lifting and/
or travelling, using the following table the identification group of the related mechanism are classifiled and then,
according to the lifting capacity, the type of hoist is determined
.
• Once the type of hoist is identified, it’s important to check the related life time in terms of hours of service and of
the total number of cycles in 10 years of operations.
Use in base of the stress level
(type of service)
Intermittent use
according to
FEM 9.683/95

use
Time of life of the lifting equipment:
• The time of life of the lifting equipment is determined from the stress level, the real running hours of each
mechanism and the number of cycles of the complete machine. The running hours and number of cycles, in
relation to the FEM/ISO of the lifting equipment selected are forecast to allow a safe life period of 10 years.
• After 10 years the lifting equipment could have finished the life of service in relation to the related group of servi-
ce. For this reason at the due time of 10 years the equipment SHOULD NOT be put any more in service without
an inspection by DONATI SOLLEVAMENTI S.r.l. expert technicians in order to check if the equipment has still some
remaining working life, so able to work in safe condition for a further period, the equipment has to be subject to
a deep technical control of all the parts.

NOTE: (1) This column indicates the FEM reference group for evaluation of normal conditions and/or the life span of the motoreducer only. The classification of the whole hoist, in any case, is the one
defined in the relative FEM service group shown in the adjacent column.
(2) Hoists with 2 falls of rope (2/1), a long (L) and extra long rope drum size 1 (X1) and hoists with 2 and 4 falls of rope (2/1 e 4/1) and an extra long rope drum size 2 (X2) use anti-twist
ropes. The type of anti-twist rope is shown in brackets.
(3) The extra long drums size 1 (X1) and size 2 (X2) are supplied without the protective roof.
