Setting Up; Preliminary Checks; Installing The Lifting Wire Rope In The Unit - Tractel minifor TR 10 Installations-, Gebrauchs- Und Wartungsanleitung

4.4.5. Hoist secured on floor
Lifting using idler pulley. Same recommendations as
for case described in 4.4.4. The strength of the pulley
and its attachment must be calculated for a double load
force (Fig. 12). Also see section 5.5.
4.4.6. Hoist bearing against surface, load freely
suspended
Strictly follow the instructions given in section 4.2. and
5.5. Be especially careful to avoid any swinging of the
load. Proceed as shown in Fig. 5.
4.4.7. Hoist bearing against surface, load not freely
suspended
This configuration requires use of an idler pulley
secured directly in line with the hoist (Fig. 6). See
sections 4.2 and 5.5.
4.4.8. Sheaving
All the above recommendations apply, especially when
sheaving is used. In this case, special care must be
taken when tensioning (see section 11).
IMPORTANT: the minifor™ TR55 can not be sheaved
as it is not equipped with a load limiter as required by
the European Directive 2006/42/CE for lifting loads over
1000kg.
NOTE: If idler pulleys are used, be careful to position
the limit stops as described in section 5.4 (Fig. 13).

5. Setting up

5.1. Preliminary checks

• Ensure that the load or force does not exceed the
maximum utilization load specified for the hoist.
• Remember that the use of idler pulleys will significantly
increase the force to be produced to lift a load.
• Ensure that the strength of the fixed point is sufficient
to safely apply a force equal to the maximum utilization
load (or twice this load in the configuration described
in 4.4.5).
• Ensure the hoist is correctly secured.
• Ensure the lifting wire rope is in good condition.
• Ensure the length of the lifting wire rope is sufficient
for the distance to be covered by the load. Provide an
additional 1.50 m for passage through the hoist and a
sufficient length of loose strand.
• Ensure the length of the electrical control cable
is sufficient to connect the device at the location
defined by the operator under safe working conditions.
5.2. Electrical recommendations
1. Before using the hoist with a new connection, refer
to the nameplate on the motor.
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 a power supply extension is used, ensure the
potential has the following characteristics:
– single phase 230 V.: 3 wires (1 phase, 1 neutral, 1
ground) with section of 2.5 mm2.
– 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 dealer.

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
agent.
5. Check that the worksite or building installation on
which the minifor™ is to be connected is equipped
with the regulatory electrical safety devices such
as a differential circuit-breaker and a ground
connection to protect the operator, the minifor™
and the equipment.
6. If the minifor™ is supplied from an electric power
generator, check that it provides (at minimum),
the required startup voltage and power. (6 kVa
for single-phase minifor™, 8 kVa for minifor™
three-phase minifor™).
5.3. Hoists with three-phase motor
(TR30S / TR50 / TR55)
The hoists equipped with a three-phase motor
have a phase direction detector inhibiting operation
should the phase order be inverted. If following
an inverted connection, the three-phase minifor™
TR30S / TR50 / TR55 does not operate, disconnect the
power connector and, using a screwdriver, turn the
imprint in the male connector by 180° to re-establish
the correct phase order (see Fig. 14).
5.4. Installing the lifting wire rope in the
unit
NOTE: Gloves should be worn when handling the wire
rope.
