6. SETTING UP
6.1. Preliminary checks
1� Load or force, less than or equal to working load limit
of hoist.
2� Strength of fixed point or bearing surface sufficient to
safely apply a force equal to the working load limit.
3� Correct rigging.
4� Minifor™ synthetic rope in good condition.
5� Length of Minifor™ synthetic rope is sufficient for
load hoisting distance. Add an additional length of
at least 1.5 m for passage through the hoist and a
sufficient length of apparent slack rope.
6� Length of electric control cable sufficient to connect
with hoist at operator position defined for safe
working conditions.
6.2. Electrical recommendations
1� Before using the hoist with a new connection,
refer
to
the
nameplate
Check the characteristics of the power supply, single
phase or three-phase, voltage, available amperage.
Check that the current supplied is compatible with
the characteristics on the motor nameplate. The
available current must be equal or greater than the
current indicated on the nameplate.
2� If an extension is used, choose an extension having
the following characteristics:
• single phase 230 V: 3 wires (1 phase, 1 neutral,
1 ground) with section 2.5 mm
• three-phase 400 V: 4 wires (3 phases, 1 ground)
with section of 2.5 mm². These characteristics are
valid for up to 50 m of electrical cable. For greater
lengths, contact your Tractel
3� The electrical extension connection must be
reinforced by an accessory ("sock") to withstand the
weight of the extension at the connector.
4� If the connector supplied with the electrical power
supply cable is to be changed, this intervention
must only be performed by a qualified technician.
Any intervention on the control box cable must also
only be performed by a qualified technician. No
intervention should be performed on the electrical
unit of the hoist (except for changing a fuse), by
anyone other than a Tractel
5� Make sure that the installation on the worksite
or building on which the Minifor™ TR125 SY is
connected is equipped with the regulatory electrical
safety devices (local and national regulations) such
as, among others, a differential circuit-breaker and
a ground connection, protecting the operator, the
on
the
motor.

Minifor™ TR125 SY and its equipment.
6� If the Minifor™ TR125 SY is supplied from an electric
power generator, check that it provides (at minimum)
the required startup voltage and power (6 kVa).
7� The Minifor™ TR125 SY three-phase hoists are
equipped with a phase direction detector inhibiting
operation if the phases are inverted. If the motor does
not operate, proceed as instructed below (procedure
to be carried out by a qualified electrician):
a) 400 V version:
– disconnect the electric power connector (item 10,
fig. 1, page 6),
– using a screwdriver, turn the notch in the male
connector by 180° to reestablish the correct
phase order (fig. 10, page A).
6.3. Installing the Minifor™ synthetic rope
in the hoist and adjusting the end
limit stops.
1� Connect the electric power connector to a power
outlet.
2� Fully insert the insertion fitting by hand in the hoist
through the opening provided for this purpose where
marked by an arrow on the casing.
DANGER: Make sure the hand holding the
Minifor™ synthetic rope is placed at least 15 cm from
the insertion opening.
IMPORTANT: never insert the synthetic rope in the
other opening which is exclusively intended for the rope
exit.
Never secure a load on a slack section of Minifor™
synthetic rope.
3� Press the "Up" button on the control pendant while
pushing the synthetic rope so that it engages on the
pulley located inside the hoist.
4� Once the Minifor™ synthetic rope is driven by the
drive system, release it�
5� When the synthetic rope comes out of the hoist,
continue the movement to obtain a length of rope of
around 1 meter coming out of the hoist.
6� On the free end of the Minifor™ synthetic rope
(item 1, fig. 13, page A), slip on the low limit stop
(item 2) then the clamping device (items 3-4-5) and
tighten the two screws (item 5) using an Allen wrench
(item 6). There should be one meter of synthetic
rope between the limit stop and the end of the
Minifor™ synthetic rope.
7� Check that the limit stop does not slide on the
synthetic rope (fig. 13, page A).
