receiver on the hoist (Fig. 22.b). The transmitter
operates on a battery. 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 keys must have the same
code. Refer to the radio remote control manufacturer's
documents supplied with the unit.
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.
NOTE: When the transmitter is oriented toward the
front of the receiver the radio range is up to 500 m. in
open field.
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 sheaving with the hoist other than the specific
minifor™ sheaving 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 a sheaving kit
against a surface.
• To use the lifting wire rope as a means of slinging a
load.
• To allow the load to swing under the hoist.
• To stand or move around under the load.
