IMPORTANT
The loose strand of the wire rope must be kept
away from the loaded strand, and more particularly,
when two loaded strands are used with sheaving
so that the loose strand does not become tangled
with the loaded strands.
For the same reasons, the loose wire rope strand
must be kept away from any obstacle which could
catch it and you should be careful to prevent the
loose strand from becoming tangled in itself;
this could result in preventing the low limit stop
attached to the loose strand from reaching the
stopping mechanisms (limit stop levers) on the
unit. Blockage of the loose strand when moving up
(load moving down) could result in rupture of the
wire rope and the load falling.
Deformation of the wire rope can also cause the
wire rope to block in the hoist or on contact of the
deformed part with the hoist. Whatever the cause
of the wire rope movement becoming blocked, the
hoisting operation should be stopped immediately.
See section 13.
The limit stops are not control components but
safety components. These should never be used
intentionally in this respect and only serve as
stopping mechanisms in the event of unintentional
overshoot of the planned travel distance.
Never park or work under the load. If necessary, set
up a safety barrier around the area under the load.
7. Shutdown – storage
Do not disconnect the wire rope hook from the load until
the load is stable and firmly bearing on a sufficiently
strong support.
The hoist can remain in position provided it is properly
sheltered from weather and located in a dry location.
Disconnect the unit electrically when not in use.
Make sure the hoist cannot be used by unauthorized
persons.
For storage, the unit can be stored in its case. The
wire rope must be removed from the unit (except those
models having a winder) and rolled on its reel.
The unit must never be set on its base when the wire
rope is engaged in the unit as this would result in
bending and damaging the wire rope.

8. Safety devices

The hoist is provided with the following safety devices:
• A no-current brake motor.
• Emergency stop control on control box – Red button
(see Fig. 2).
• Mechanical interlock, prohibiting simultaneous action
of Up and Down controls.
• Very-low voltage control (48 V) for three-phase units.
• High and low limit levers on unit, working with stops
on wire rope.
• Safety latches (1) on hooks (Figs. 16 and 17)
• Electrical protection for control box: class 2.
• Control protection fuse, in electrical unit.
• electrical load limiter on minifor™ TR110.
The emergency stop function is ensured by pressing
the red button (Fig. 2). To restart the unit after an
emergency stop, the emergency stop button must be
unlocked by turning it in the direction of the arrows
marked on the button, after having ensured that all the
emergency conditions have been eliminated.

9. Lifting wire rope

The minifor™ wire rope is equipped with a safety hook
at one of its ends. The hook is mounted on a wire rope
loop equipped with a lug crimped in a metal sleeve (see
Fig. 17). The other end is welded and ground. This end
must be maintained welded, rounded and free of any
irregularities (see Fig. 18).
To ensure safe use of the minifor™ hoists, they must
only be used with the minifor™ wire rope specially
designed for the hoist (diameter of 6.5 mm).
Use of a damaged or inappropriate wire rope
represents a serious risk of accident and failure.
The condition of the wire rope should be monitored
regularly and the wire rope should be immediately
eliminated if it shows any sign of damage such as
deformation, bending or broken wires (Fig. 19). Any
wire rope whose nominal diameter has been reduced
by 10% or which has more than 10 broken wires over a
length of 200 mm should be eliminated. Standard ISO
4309 (Measure as shown in Fig. 20).
Do not expose the wire rope to temperatures exceeding
100°C or to any corrosive mechanical or chemical agents.
Store the wire rope wound on its reel in a location which
is free of humidity after having carefully cleaned and
lubricated the wire rope along its entire length. Do not
use grease or oil containing molybdenum disulphide or
graphite additives.

10. Servicing

Servicing the unit consists in regularly checking that it is
in good condition, in cleaning it and having it periodically
inspected (at least once a year) by a TRACTEL
approved repair agent. No greasing or lubrication of
the unit is required by the user. (For maintenance of
the lifting wire rope, see section 9). Check that the
