(Fig. 22.a) and a receiver on the hoist (Fig. 22.b).
The transmitter operates on a battery. A charger
(supplied with 100 to 250 Vca with 12 Vcc 150 mA
output) is supplied. The radio remote control
enables the user to control the up, down and
emergency stop functions of the hoist with no need
for a control cable. It operates by transmission of
an encoded RF wave.
The code for each unit can be modified by the
user, in particular when several remote-control
hoists are used at the same site. The transmitter and
receiver each contain an 8-key encoder.
The transmitter and receiver keys must have the
same code. The encoders are accessed by
unscrewing the covers on the transmitter and
receiver. Refer to the radio remote control
manufacturer’s documents supplied with the unit.
Check that the antenna is on the unit before using
the system (Fig. 23).
The radio remote controlled minifor
™
should
only be operated from a location where the load
movements are clearly visible. When this is not
possible, appropriate measures should be taken
to eliminate any uncontrolled hazards which
could arise.
Note : The transmitter unit must be used and
handled with care and is subject to damage from
shocks.
NOTE : Unless the codes are changed accordingly,
any command generated from the transmitter will
cause the same and nearly simultaneous
movement of all the radio remote controlled hoists
located on the same site within range of the radio
remote control transmitter.
The transmitter has a range of around 30
meters.
NOTE : When performing an operation, keep in mind
that the system has a slight reaction time. For this
reason, it is not possible to control several
hoists from a single transmitter in a perfectly
synchronized way.
This radio remote control system is approved in
France by the Telecommunications Authorities
(ART) and does not require any individual license
for use. No changes should be made to the radio
remote control system.
Use of the radio remote controlled minifor
™
outside France is subject to verification for
compatibility with local regulations concerning radio
waves.
The radio remote controlled minifor
™
s do not
come with a control box connected by a control cable
(optional, on request).
13. RECOMMENDATIONS FOR USE
When used in compliance with the information
given in this manual, the minifor
™
hoists are entirely
safe. The hoist operator should however be careful
never to use the minifor
™
inappropriately as
described below :
IT IS PROHIBITED :
• To use a minifor
™
hoist, even occasionally, to lift
persons.
• To use a minifor
™
hoist for operations other than
those for which it is designed or using installation
diagrams other than those described in this
manual.
• To use a hoist beyond its maximum utilization
load specification.
• To set up the hoist under conditions which may be
dangerous to the operator.
• To fasten a load to the hoist hook and fasten the
cable hook to a fixed point.
• To anchor the hoist by its handle.
• To start up the unit without first checking that the
limit stops are correctly positioned.
• To connect the unit to an electrical connector
without first ensuring that the power supplied
matches the hoist specifications and that the
power circuit is equipped with the regulatory
electrical safety devices.
• To secure the hoist in a structure (except as
described in section 4.2) or to interfere with self-
alignment on the cable.
• To use tackle with the hoist other than the specific
minifor
™
tackle kit designed for the minifor
™
hoist.
• To pull a load along the floor using a unit which is
not properly aligned with the movement of the
load.
• To force operation if the wire rope is blocked in or
against the hoist.
• To operate a hoist using a three-phase power
supply with commands inverted with respect to the
direction indicated.
• To apply a load on the loose strand of the lifting
wire rope.
• To use a minifor
™
equipped with tackle bearing
against a surface.
