Tractel Tralift Gebrauchs- Und Wartungsanleitung Seite 9

6. Check that the pulley block (item 3 fig. 1 &
1a) 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
(fig. 4).
8. Check that the load chain is neither twisted
or damaged. Check in particular that the
load chain is correctly positioned in the unit's
drive sheave.
9. Check that the hand chain is in place and is
not tangled with the load chain.
10. Ensure that the strength of the hoist
anchoring point is greater than or equal to
the load to be lifted.
After successfully completing the preliminary
checks, install the hoist on its anchoring point
and perform the following checks:
1. Check that the Tralift or Tralift Duratech hoist
is properly suspended by its suspension
hook (item 5, fig. 1 & 1a) and the safety latch
(item 6, fig. 1 & 1a) are securely closed.
(See fig. 2 and 3.)
2. Check that the load chain has not been
subjected to any torsion when setting up, in
particular for the two-fall version. (See fig. 4.)
3. Without a load, check the "Lifting" and
"Lowering" functions. (See §5.3.)
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 fig. 2 and 3.)
2. the load on the hoist is free to align itself with
the machine's anchoring point.
5. Operation
5.1. Operating principle
The Tralift or Tralift Duratech hoist is actuated
using the hand chain which you must pull to lift
or lower the load applied.
5.2. 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 (live end
pulley facing you).
5.3. Manoeuvring the hoist
Facing the live end pulley (located opposite the
marking), 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.
5.4. Important additional instructions
When taking the Tralift or Tralift Duratech 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.
6. 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 hand chain
and load chain with a brush and lubricate with
machine oil.
