HOIST GEAR DRIVE
GENERAL INSTRUCTIONS
Recycling
(keeping in mind the instructions in force):
– the elements of casing, gear pairs, shafts and bearings
of gear reducer must be transformed into steel scraps. The
elements in grey cast iron will be subjected to the same
treatment if there is no particular instruction;
– the worm wheels are made in bronze and must be
treated adequately;
– exhausted oils must be recycled and treated according to the
instructions.
The paragraphs marked with present symbol contain dispositions
to be strictly respected in order to assure personal
safety
and
to avoid any heavy damages to the machine or to the
system (e.g.: works on live parts, on lifting machines, etc.);
the responsible for the installation or maintenance must
scrupulously
follow all instructions contained in present
handbook.
1 - GENERAL SAFETY INSTRUCTIONS
Gear reducers and gearmotors present dangerous parts because
they may be:
– live;
– at temperature higher than +50°C;
– rotating during the operation;
– eventually noisy (sound levels > 85 dB(A)).
An incorrect installation, an improper use, the removing
or disconnection of protection devices, the lack of
inspections and maintenance, improper connections may cause
severe personal injury or property damage. Therefore the component
must be moved, installed, commissioned, handled, controlled,
serviced and repaired
exclusively by responsible qualified
personnel (definition to IEC 364).
It is recommended to pay attention to all instructions of present
handbook, all instructions relevant to the system, all existing safety
laws and standards concerning correct installation.
Attention!
Components in non-standard design or with constructive
variations may differ in the details from the ones described here
following and may require additional information.
Attention!
For the installation, use and maintenance of the electric
motor (standard, brake or non-standard motor) and/or the electric
supply device (frequency converter, soft-start, etc.) and accessories,
if any (flow indicators, independent cooling unit, thermostat, ecc)
consult the attached specific documentation. If necessary, require it.
Attention! For any clarification and/or additional information consult
Rossi and specify all name plate data.
Gear reducers and gearmotors of present handbook are normally
suitable for installations in industrial areas: additional protection
measures
, if necessary for different employs, must be adopted and
assured by the person responsible for the installation.
IMPORTANT
: the components supplied by Rossi must be
incorporated into machinery and should not be commissioned
before the machinery in which the components have been
incorporated conforms to:
– Machinery directive 2006/42/EC and subsequent updatings; in
particular, possible safety guards for shaft ends not being used
and for eventually accessible fan cover passages (or other) are
the Buyer’s responsibility;
– Electromagnetic compatibility (EMC)» directive 2004/108/ EC
and subsequent updatings.
When operating on gear reducer (gearmotor) or on components
connected to it the machine must be at rest : disconnect motor
(including auxiliary equipments) from power supply, gear reducer
from load, be sure that safety systems are on against any accidental
starting and, if necessary, pre-arrange mechanical locking devices
(to be removed before commissioning).
If deviations from normal operation occur (temperature increase,
unusual noise, etc.) immediately switch off the machine. The
products relevant to this handbook correspond to the technical
level reached at the moment the handbook is printed. ROSSI
MOTORIDUTTORI reserves the right to introduce, without notice, the
necessary changes for the increase of product performances.
2 - OPERATING CONDITIONS
Gear reducers are designed for industrial applications according
to name plate data, at ambient temperature 0 ÷ 40°C (with peaks
at -10°C and +50°C), maximum altitude 1 000 m.
Not allowed running conditions: application in aggressive
environments having explosion danger, etc. Ambient conditions
must comply with specifications stated on name plate.
3 - HOW SUPPLIED
3.1 - RECEIPT
At receipt verify that the unit corresponds to the one ordered and
has not been damaged during the transport, in case of damages,
report them immediately to the courier.
Avoid commissioning gear reducers and gearmotors, that are even if
slightly damaged.
3.2 - NAME PLATE
Every gear reducer presents a name plate in anodised aluminium
containing main technical information relevant to operating and
constructive specifications and defining, according to contractual
agreements, the application limits (see fig. 1); the name plate must
not be removed and must be kept integral and readable. All name
plate data must be specified on eventual spare part orders.
3.3 - PAINTING
Products are painted according to the painting table shown on
page 20. Before adding further coats of paint (use dual-compound
paints only), properly protect the seal rings (which must neither be
damaged nor painted), degrease and sand the gear reducer (or
gearmotor) surfaces.
