Maintenance - IMER USA PULL UP 650 Manual De Uso & Mantenimiento

- 5) If the load requires accessories to be attached or
hooked up, these must be certifi ed and approved (harnesses,
ropes, slings, etc.). The weight of these accessories must be
subtracted from the maximum capacity.
- 6) Ensure that no part of the load protrudes during the
lifting process.
- 7) Before releasing the load, ensure that it is in a stable
position.
- 8) A suspended load must never be detached by a sud-
den release or by cutting the slings, this causes a backlash
movement of the entire structure.
- 9) Never move hands or parts of the body near the hoist
during operation, as this constitutes a risk of entrapment with
the cable, with the risk of serious accidents.
- 10) Never move hands or parts of the body near the cable
counterweight during the lifting process, as this constitutes a
risk of crushing or pinching with the limit switch lever.
- 11) Avoid use in adverse weather conditions (strong
winds or storms) as the load will not lift straight up.
- 12) There must be adequate lighting at the hoist and at
the lifting and discharge positions.
- 13) Ensure that all guards and safety devices are in
place and in working order.
- 14) During use, check that the cable unwinds correctly,
turn after turn, without slackening or twisting, which can
cause damage to the cable. If this occurs, unwind the rope
and rewind it correctly keeping the cable properly tensioned
at all times.
- 15) Ensure that the travel and work areas are free of
obstacles throughout the lift height and take the necessary
precautions to prevent persons from leaning out of interme-
diate fl oors.
- 16) Clear the lower load area to prevent persons from
being present during lifting.
- 17) Keep children at a safe distance from the hoist.
- 18) When the hoist is not in use, do not allow unautho-
rised personnel access or operation.
- 19) Use of the hoist must be for straight up and down
(do not exceed over 5° with respect to vertical angle).
- 20) Never move the elevator by pulling the pendant
control; it must always be moved manually from the frame.
- 21) Do not leave a suspended load unattended. Raise
or lower it and unload it.
- 22) During lifting or lowering, never allow the load to
twist as this may cause the cable to break.
- 23) Before leaving the hoist unattended, remove the
load, wind the cable completely onto the drum, detach the
power plug from the power source and protect the hoist
from the rain.
- 24) When a load is to be raised or lowered, this must
be done in such a way as to minimise dangerous sideways
and vertical movements. Do not allow the load to swing back
and forth.
When operation is resumed after an extended period of inactivity
(i.e. overnight) the entire machine must be tested under no-load
conditions before starting (as described in section 5).

7. MAINTENANCE

- Warning!! All maintenance work must be carried out
with the machine switched off, unloaded and disconnected

7.1.1 REPLACING THE CABLE (Fig. 5)
The cable must be replaced by
a qualifi ed service technician.
Fig. 5.1: remove the hook (4) by
unscrewing bolt (5).
Remove the clamp (1), push on
the wedge (2) and extract the
cable from the block (3).
Completely unwind the cable.
Extract from the inside of the
drum through the hole and slot.
Remove it from inside the drum
through the hole and slot. Insert
the new cable in the hole and
thread it through the slot in the
drum tube. Tighten the clamp at
the end, leaving about 1/2 inch of
cable free (fi g. 5.2), and pull the cable until the clamp comes into
contact with the inner wall of the drum.
tact with the drum surface (fi g. 5.3).
Now wind on the cable in adjacent turns, one layer at a time.
Insert the cable into the counterweight and the block (Fig. 5.4).
Pass the cable back through the counterweight and the block.
