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, fig. 1) and the
safety latches (item 6, fig. 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, fig. 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 com -
prising 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,
fig. 1) and that the hook safety catch
(item 6, fig. 1) is properly closed (see figs 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
fig.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 figs. 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.
