3. INSTALLATION
Before installing the tralift™ hoist make the following
checks:
1. Check that the hoist is in good condition.
2. Check that the load to be lifted is less than or equal
to the WLL* of the hoist.
3. Check that the hook (item 2, g. 1) and the safety
latches (item 6, g. 1) are in good condition.
4. Check that the end of the load chain, slack strand
side, is secured to the low limit stop of the hoist (item
4, g. 1).
5. Check that the markings comply with §9.
6. Check that the pulley block shows no signs of
damage and that the load sheave turns freely.
7. When using a hoist with load chain comprising
several strands, make sure that the strands are
neither tangled or twisted.
8. Check that the load chain is neither twisted or
damaged.
9. Check that the hand chain is in place and is not
tangled with the load chain.
10. Make sure that the strength of the hoist anchor point
is greater than or equal to the load to be lifted.
After successfully completing the preliminary checks,
install the tralift™ hoist on its anchoring point and
perform the following checks:
1. Check that the tralift™ hoist is properly suspended
by its suspension hook (item 5, g. 1) and that the
hook safety catch (item 6, g. 1) is properly closed
(see gs 2 and 3).
2. Check that the load chain has not been subjected to
any torsion when setting up, in particular for the two-
strand version (see g.4).
3. Without a load, check the “Lifting” and “Lowering”
functions (see §4.3).
4. When using the hoist with a push suspension trolley,
without load, check that the trolley moves freely. If
using a geared suspension trolley, without load,
check the direction of movement by pulling on the
trolley hand chain. The movement should be carried
out on a strictly horizontal plane.
After successfully completing these checks, place the
load in position and ensure:
1. the anchoring accessory of the load sits fully in the
hook and does not prevent the catch from closing
correctly (see gs. 2 and 3).
2. the load on the hoist is free to align itself with the
machine’s anchoring point.
4. OPERATION
4.1. Operating principle
The tralift™ hoist is actuated using the hand chain
which you must pull to lift or lower the load applied.
4.2. Installing the lifting hook on the load
rigging point
If installation of the lifting hook requires adjustment of
the chain length, proceed as follows:
1. Make sure that there is no load on the chain.
2. Secure the lifting hook to the load.
3. Slightly tension the load chain by pulling on the RH
strand of the hand chain.
4.3. Maneuvering the hoist
Facing the load pulley, proceed as follows to lift or lower
the load:
4.3.1. To lift the load, pull on the RH strand of
the hand chain
4.3.2. To lower the load, pull on the LH strand
of the hand chain
Do not operate the chain too quickly as this can result
in jolts when lifting or lowering a load. The hand chain
should be pulled by a smooth, regular action to avoid
any swinging of the load.
4.4. Important additional instructions
When taking the tralift™ hoist out of service ensure that
there is no load applied and that the load chain is slack
enough to enable the bottom hook to be removed from
the load.
5. STORAGE
It is recommended that the hoist be stored hanging so
that the load chain does not become tangled. Store the
hoist in a dry and weather-proof area. Before storage
clean the load chain with a brush and lubricate with
machine oil.
6. LOAD CHAIN
The good condition of the load chain is a guarantee of
safety and at the same time the good operation of the

7
GB
hoist. It is therefore necessary to constantly be aware
of the condition of the load chain and to clean and
lubricate with machine oil at regular intervals.
The load chain must be examined daily by a com petent
person when the hoist is being used.
Do not expose the load chain to excess tem peratures or
abrasive or chemical materials.
Protect the chain against all possible damage such as
from welding arcs.
7. MAINTENANCE
Periodically, or at least once every year, and in
accordance with the safety regulations applicable in the
country of use, the hoist must be inspected and tested
with load by quali ed maintenance personnel.
Periodically, and in particular following intensive use,
lubricate the mechanical parts, including the pulley
block. The components of the brake and friction limiter
must never be lubricated and should always be kept
clean and dry.
Regularly check the condition of the hooks. If the
deformation between the hook opening indicators is
greater than 2 mm, (Fig. 5.2, distance “M” given in
table of § 2 Technical speci cations), the unit must be
considered as damaged and removed from service.
If any damage is observed, return the tralift™ hoist to a
TRACTEL®-approved repair workshop.
8. EMERGENCY PROCEDURE IN
CASE OF AN INCIDENT
In the event of a blocked chain or any other malfunction
of the unit, immediately stop the maneuver without
attempting any further actions and call in the necessary
quali ed personnel to remove the load and intervene
on the hoist.
Immediately set up a safety perimeter around the hoist
and directly under the load to prevent access by any
unauthorized persons.
Return the hoist to a TRACTEL-approved repair agent.
9. MARKINGS
9.1. standard marking
