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.

It is fitted with a series of thermal probes to protect against overloads.
Three-phase asynchronous motor DRH4 24kW cylindrical.
2 - Lifting brake
• The conical brake is fitted with an asbestos-free friction gasket. The brake block, made up of a fan which ensures
the cooling of the brake itself and of the motor, moves on its axis with the motor shaft, and the braking function
is activated automatically in case of power failure.
[RES. 1.2.6 - 4.1.2.6 c) - Attachment I Machine Directive]
Electro-magnetic brake DRH4 24kW.
3 - Joint
• It connects the self-braking motor and the reducer, allowing perfect axial running of the motor shaft.
4 - Gearbox
• Coaxial, with 3 reduction stages, produced with cylindrical high-resistance steel gears, which are helical-toothed
and heat treated. Designed to resist fatigue and wear and tear for life relating to the FEM service group [RES.
4.1.2.3 - Attachment I Machine Directive].
It is entirely installed on ball bearings lubricated for life in an oil bath.
5 - drum shell
• The drum, made of steel tube and mechanically channelled, is supported by the reducer flange and the
flange on the equipment side, with hubs with swivel broached holes on permanently lubricated bearings.
The drum is designed following the standards ISO 4308-1/86 and UNI 9466 and also the FEM rules
9.661/86. The support flanges of the drum are fitted with cylindrical steel pins to fix the suspension and
settingdown components of the hoist. Mechanically-made housings support the terminal head crossbar
and the transmission pulley. The connection between the two flanges is made with bolted staybolts.

6 - Rope guide
•
Formed by a threaded ring made of spheroidal graphite cast iron, the rope guide allows an optimal winding of
the wire rope on the drum [RES. 4.1.2.4 - Attachment I Machine Directive]. An elastic system allows the
automatic registration of clearance and wear and tear.
The rope guide has sliding-block reaction arms made of brass which, acting on the stay bolts of the rope drum
cover, act as actuators of the ascent and descent limit switches.
7 - Lifting limit switches
• A component with safety functions which limit, in case of emergency, the hook’s ascent and descent run [RES.
4.1.2.6 a) - Attachment I Machine Directive]. It is formed of two precision micro switches which function
according to the principle of “slow positive opening” and work on the auxiliary circuit of the control device of
the lifting motor.
8 - Pulley crossbar
• Used in the executions at 4 falls, it is supported by two pivots which allow it to position along the
vertical axis of the wire rope. It is fitted with a transmission pulley made of carbon steel with a mechanically
channelled rope race and swivelling on ball bearings with permanent lubrication.
9 - Terminal head crossbar
• Used in the executions at 2 and 4 falls, it is supported by two pivots which allow it to move on the vertical
axis of the wire rope. The overload device is located between the cross head plates.
8a/9a - Pulleys and terminal head support
• Used in the executions of 6 and 8 falls, consist of a welded structure and is designed with a junction plate to
be located on the double girder carriage. It is equipped with pulleys made of carbon steel mechanically groo-
ved and swivelling on bearings with permanent lubrification. The overload device is located on the support in
the anchorage crosshead.
10 - The overload device
• All DRH electric wire rope hoists are fitted with overload devices, with a micro switch for an intervention
threshold [RES. 4.2.1.4 – Attachment I Machine Directive]. The overload device constantly measures and checks
the weight of the load and the dynamic and inertial effects due to handling. If the set calibration readings are
exceeded, the micro switch on the device intervenes by opening the control circuit of the lifting control device.

related trolley are activated with electrical equipment including:
• The transformer for the low voltage power supply of the control circuits
• The general line contactor and the contactors/inverters for the control of the motors
• The protection fuses of the motors and of the transformer
• The terminal block for the connections of the auxiliary and power circuits.
The components are fitted on a hinged panel and fixed in the space located on the opposite side of the motor.
The controls are activated by the pendant push-button panel powered in low voltage AC at 48V.
The push-button panel, of ergonomic shape, made of self-extinguishing shockproof thermoplastic, is water
resistant to IP65 protection. The emergency stop function [RES. 1.2.4.3 - Attachment I Machine Directive], is
produced with a mushroom-head push-button which using an intentional release action puts the control circuit
in the forward position [RES. 1.2.3 - Attachment I Machine Directive].
The push-button panel is connected to the electrical equipment by a multipolar electrical cable fitted with tear
proof metallic parts.

6 - Rope guide
•
Formed by a threaded ring made of spheroidal graphite cast iron, the rope guide allows an optimal winding of
the wire rope on the drum [RES. 4.1.2.4 - Attachment I Machine Directive]. An elastic system allows the
automatic registration of clearance and wear and tear.
The rope guide has sliding-block reaction arms made of brass which, acting on the stay bolts of the rope drum
cover, act as actuators of the ascent and descent limit switches.
7 - Lifting limit switches
• A component with safety functions which limit, in case of emergency, the hook’s ascent and descent run [RES.
4.1.2.6 a) - Attachment I Machine Directive]. It is formed of two precision micro switches which function
according to the principle of “slow positive opening” and work on the auxiliary circuit of the control device of
the lifting motor.
8 - Pulley crossbar
• Used in the executions at 4 falls, it is supported by two pivots which allow it to position along the
