NOTE: If you wish to further limit the travel
distance of the load downward, run the synthetic rope to
the desired length before you secure the limit stop.
On the other end, secure the upper limit stop clamping
device in accordance with the height at which you want
to limit the travel of the load upward. Secure and check
by applying the same procedure performed for the low
limit stop.
Check that the hoist limit levers operate correctly, as
well as the other safety devices as described in section
9�
DANGER: It is an absolute safety requirement to
ensure that there is a limit stop at around one meter
ahead of the free end of the synthetic rope and another
EN
limit stop on the hook side of the synthetic rope, both
securely and appropriately fastened.
6.4. Check with load
With the load fastened, lift it slightly and check that the
"Up" and "Down" controls operate correctly; also check
operation of the "Emergency stop" control.
Once you have ensured that these functions operate
correctly, you can proceed with the maneuvers.
If the unit does not operate correctly, return it to a
Tractel
-approved repair agent (Also see section 6.2).

7. OPERATING THE HOIST
The hoist is operated by pressing on either the "Up" or
"Down" button on the control box (fig. 3, page A). The
control box must always be held in the vertical position,
hanging on its control cable. Never turn over the control
box (control cable entry downward) as this can result in
control mistakes.
When the "Up" or "Down" button is released, the
movement stops
IMPORTANT: For lifting operations at great heights
using a single phase Minifor™ TR125 SY hoist, the unit
should be stopped for around 15 minutes after
15 minutes of operation for the 230 V versions and after
10 minutes of operation for the 115 V versions.

DANGER: The temperature of the hoist casing,
when the unit is operating, can reach 80°C. Beware that
any contact with the hoist casing can result in severe
burns.
The red emergency stop button is used to immediately
stop movement in the event of a malfunction of the
"Up" or "Down" button (item 1, fig. 3, page A). (see § 9:
Safety devices).
The following precautions must be taken when
performing up or down movements:
– the load should not swing or turn,
– keep all possible obstacles at a distance from the
synthetic rope and from the load,
– check that the loose strand is free along its entire
length,
– do not allow the loaded strand to become loose
if the load is not stable on a sufficiently strong
support,
– do not apply short successive actions on the
pushbuttons,
– make sure that the load to be moved is not
attached or blocked by anything external to the
lifting device.
DANGER: It is essential to keep the slack away
from the loaded rope and the two loaded ropes in the
rigged assembly, so that the slack does not tangle with
the other ropes. For the same reasons, the loose 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) can result
in rupture of the synthetic rope and falling of the load.
A deformation of the Minifor™ synthetic rope can also
result in jamming of the hoist. Whatever the cause of a
jam, be sure to immediately stop the maneuver.
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 remain stationed or work under a load. Mark out
the working area using barriers to prevent anyone from
passing under the load.
Never use the hoist to lift or carry persons.
