4. TRANSPORT AND STORAGE
4.1 Handling
All gearless machines are packed in crates or cages.
Different types of packaging can be used, depending on the size and means
of transport. Unless otherwise specified, the packaging complies with the HPE
guidelines.
In some cases, the machines are mounted on wooden pallets to enable them
to be transported correctly on trucks. The packaging may not be stacked in any
way. It is recommended to check the conditions of the material when it is re-
ceived. In case of damage, do not proceed with the installation unless expressly
authorized by Montanari Giulio & C. Observe the symbols on the packaging to
prevent damage to property or personal injury. Here are the meanings of the
symbols that may appear on the packaging.
Keep dry Handle with care

4.2 Storage
The gearless machine must be stored in the position of use on a wooden base
not subject to vibrations, in a covered and sheltered place.
If the unit is stored outdoors, it should be covered, taking care that no
moisture and/or other foreign matter can accumulate on it.
!
Supplies for special environmental conditions during transport (e.g.
by ship) and storage (climate, temperature, etc.) must be contractually
agreed.
!
• Check the correct operation of the motor and brake after installation.
• Repairs may only be carried out by the manufacturer or by authorised per-
sonnel.
• The machine can be red-hot.
• These machines must be connected to inverters.
• When the machine is rotating, both manually and mechanically, it can act as
a generator and produce high voltage.
• During configuration, the machine is powered by high voltage.

5. DESCRIPTION
5.1 General description
The MGV34 series gearless machines are permanent magnet motors with dou-
ble brake system.
5.2 Main components
The unit consists of the main groups as shown in Fig. 7 - 8 - 9. For the versions
with 400 - 480 - 520 mm sheave, it is possible to install the kit for the manual
rescue system.
MGV34 S- M - ML - L are equipped with a PTC thermal probe inside the windings
to protect against overheating (winding temperature up to 130°C) and with a
thermo-contact for the activation of the fans. Refer to the electrical connections
for more details. - See Par. 6.4.
Lubrication
The gearless machine contains no oil and it is supplied with bearings
already lubricated throughout the life of the machine; no further lubri-
cation is required.

5.3 Brake
The gearless machine is supplied with a brake that conforms to the standards
indicated in paragraph 2.5.
The brake system is pre-calibrated by the manufacturer and no further adjustment
is required.
The brake system operates as follows:
• Not powered (electromagnet not powered): the brake disc is clamped by
the movable surfaces (yellow arrows on Fig. 10). In this condition the system
does not move.
• When the brake electromagnet is powered, it releases the brake disc
(yellow arrows in Fig. 11); now the motor is released.
