4. OPERATION
4.1 OPERATING PRINCIPLE
The bravo™ hoist is operated by means of an
actuating handle (item 7, fig. 1) which is
moved back and forth by the operator to lift or
lower a load, pull a load, or apply tensioning.
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. Set the movement selector lever (item 8,
fig. 1) to the neutral position “0”.
3. With no load on the machine, turn the load
wheel (item 9, fig. 1) anti-clockwise to open
the brake; the chain is released.
4. If it is not possible to turn the load wheel put
the selector lever in the down position and
operate the lever handle wrilst exerting
some force on the hook side of the chain
with your hand. Place the selector lever in
the “neutral” position and pull on the chain,
which is thus released, using the low limit
stop.
5. Secure the lifting hook to the load (or to a
fixed point), or to the point where tension
will be applied. Apply a slight tension to the
chain by pulling on the chain using the low
limit stop.
6. Turn the load wheel clockwise; the brake is
closed. The chain is engaged in the hoist.
4.3 MANEUVERING THE HOIST
1. To lift, pull or tension: put the selector lever
to position
↑
and operate the lever handle
back and forth.
For a hoist equipped with the load limiter
option: if the load is greater than 1.5 x WLL*
(average), the operatorʼs action on the lever
will not have any effect on the load and, under
these conditions, it will be impossible to lift the
load.
Important : Repeated triggering of the limiter
can result in wear causing a decrease in the
load limitation threshold. In this case, the unit
must be checked by TRACTEL
®
.
2. To lower or slacken: put the selector lever to
position
↓
and operate the lever handle
back and forth.
4.4 IMPORTANT ADDITIONAL
INSTRUCTIONS
1. When taking the bravo™ 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.
2. The selector lever must not be left in
the neutral position “0” when a load is
suspended or the hoist is tensioned. Make
sure that the selector lever is in the desired
position and is not located between two
positions.
3. Do not attempt to operate the load wheel
during any operation or when a load is
suspended on the hoist.
4. It is not recommended to operate the lever
handle at excessive speed as this will lead
to an uneven movement of the load. It is
recommended to operate the lever handle
in a steady movement to prevent any
unnecessary jerking of 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 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
competent person when the hoist is being
used (see technical data sheet T 2208).
Do not expose the load chain to excessive
temperatures, abrasive materials or chemi cals.
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 qualified
maintenance personnel.
Periodically, and especially after an intensive
use, lubricate the mechanical parts. Never let
brake discs receive some lubricant. They have
to be kept clean and dry.
Regularly check the condition of the hooks.If
