Pfeifer RHINO Traducción Del Manual Original página 17

Preparations
Ensure that:
• the RHINO lever hoist is of sufficient dimensions for
the planned use.
• the load is no lighter than the minimum load.
• suitable attachment devices such as chains or rope
slings for attaching the load are available if required.
• the attachment point is of adequate dimensions, and
that the equipment can align itself freely. Avoid parallel
shear pull (Fig. 5)!
• the specified WLL is not exceeded
Releasing the chain
Place the control lever in the neutral (central) position.
The chain can be pulled in either direction, and slack
can quickly be taken out of the load chains.
Raising the load
Put the control lever into the lift (up) direction, and allow
it to engage. Make pumping movements with the hand
lever. If the hoist is kept under load but is not being
worked with, the control lever must be put into the lift
(up) position. Always suspend the load in the centre of
the hook. Do not load the hook tips (Fig. 9).
Lowering the load
Put the control lever into the lower (down) direction, and
allow it to engage. Make pumping movements with the
hand lever.
Engaging the brake
The brake will remain engaged if, because the load is
lifted or in the course of demolition work, the tension
is suddenly released from a hoist that is under load
without first initiating lowering. The brake also engages
if the load hook with the lower block is pulled too tightly
against the housing.
Releasing the engaged brake
Place the control lever in the lower (down) position,
and jerk the hand lever. If the tension is extremely high,
the brake can be released by suddenly loading the
hand lever.
Possible faults
Only use the device – and auxiliary equipment – that is
free from faults. If any faults occur during use, the work
must be halted, and the working area must be made
safe if necessary.
ATTENTION: Due to load oscillations
(dynamic load effects), the load may
(briefly) fall below the minimum,
which can lead to the load falling.
The chain can quickly and easily be adjusted to the
correct length in free running by setting the switch
lever to "N" (neutral). To release the brake, turn the
handwheel anti­clockwise until it blocks. The chain
can now be pulled freely in each direction.
Avoid lifting or tensioning procedures in the free
running position. Furthermore, the free running
setting must on no account be selected under load.
5. Limits of use
CAUTION: never let the load chain run
over sharp edges
5.1 Limits of use
• Not suitable for use in direct contact with food or
pharmaceutical products that require high cleanliness.
• Not suitable for handling special hazardous materials
(explosives, molten masses, radioactive materials)
• Not suitable for use in rooms with potentially
explosive atmospheres.
• Not suitable for continuous operation.
• The lifting of loads weighing less than 10 % of the
imposed load is forbidden.
• The net weight of the 3 t and 6 t models exceeds
20 kg. It is dangerous to transport the lever hoist
alone; a minimum of two people are required.
Any change or modification to the lever hoists is
forbidden!
Lever hoists must not be used outside the listed
temperature ranges. The lever hoists must be taken
out of service immediately after use outside the
specified temperature ranges.
