- apply two anchor bolts;
- fit a ballast container.
- Do not assemble the hoist before securing the
support with the two anchor bolts or ballasting.
7.1 ANCHORING THE SUPPORT WITH TWO BOLTS (fig. 8)
A bolt (minimum diameter M14 and minimum strength class 8.8)
must be inserted in the 15 mm diameter hole at the end of each
of the two feet and through the floor and a bearing plate of
adequate size to withstand the force exerted by the anchor
bolts on the floor (fig. 8) must be fitted under the head of the
nut.
The maximum force transmitted by each of the two bolts is
approx. 4000 N.
7.2 FITTING THE BALLAST CONTAINER
If the anchor bolts cannot be fitted, a ballast container is available
(fig. 9), which must rest symmetrically on both feet of the
support.
The ballast container consists of two side panels (1), two end
pieces (2), two lids (3), two supports (4), a locking bar (5) and
two tie rods (6).
To assemble, fit the two side panels together to form the V
shape present on the base and tighten them using the special
brackets, bolts, washers and nuts provided (fig. 10). Fit the
two end pieces and screw them to the respective side panels.
Screw the two supports (4) under the side panels and the four
screws in position P (fig. 9) to prevent the container from
falling of the feet.
Fit the two tie rods and the locking bar (5) to join the two side
panels at points Q (fig. 9). The locking bar must be positioned
mid-way between the two tie rods with the tab upwards.
Fill the ballast container with at least 840 kg of material having a
specific weight of not more than 1300 kg/m3 (e.g. dry sand).
Liquid must not be used as ballast.
In order to prevent tampering with the ballast, the container
must be closed with the two lids and a padlock applied on the
hole in the locking bar tab (5).
Never use makeshift systems such as bags of cement or by
stacking bricks as ballast, as they cannot guarantee safe
anchoring of the structure.
- The ballast must not be removed until the hoist
has been dismantled from the support.
8. CHECKS AND MAINTENANCE
- Important. All maintenance work must be carried
out with the machine stopped, the load removed and the
power plug disconnected.
- Repairs must be carried out by qualified personnel or at the
IMER Technical Assistance Centres.
- Only use original spares for replacing faulty parts.
- Check the efficiency of the electric motor brake
every 6/7 days.
- Always keep wording and symbols on the machine
legible.
- Keep the machine clean of dirt.
- Ensure constant efficiency of the Up limit switch,
checking its operation at the start of every work shift.
- Always check the state of the power cable before
using the machine, as it may have been accidentally
damaged.
- At the start of every work shift check that the pulley
turns freely.
- Grease the pulley bearings every 6-7 days.
8.1 STEEL WIRE ROPE
Only use new ropes with characteristics as specified below,
complete with certificate of conformity and identification.
- External diameter 5 mm
- Type 133 wires (19x7) anti-spin
- Direction of lay crossed right-handed
- Strand strength 1960 N/mm²

8.1.1 REPLACING THE ROPE (Fig. 5)
Replacement must be carried out by a
qualified maintenance technician.
Remove the hook (ref. 2, fig. 1) and
remove the counterweight (10, fig. 1).
To avoid stress on the rope attachment
point the drum is fitted with a device to
ensure that two turns of rope remain
on it even when fully unwound.
When replacing the rope, it must be
fitted as follows.
Unwind the rope completely. Remove it
from inside the drum through the special
Fig. 5.2
On the second turn, pass the rope under the hook located
inside the slot in the drum (fig. 5.3).
Pull the rope to ensure contact all
around the cylinder.
Wind the rope, correctly laying turn
on turn in consecutive layers.
Insert the rope in the counterweight
(fig. 5.4) and aluminium sleeve.
Insert the thimble in the hole of the
hook.
Run the wire rope back through the
sleeve and tighten the thimble in
the loop formed. Approx. 1 cm of rope must protrude from the
sleeve.
Pull the rope to tighten all the parts together. Then press the
aluminium sleeve with a suitable press or tool. Check that the
Up limit switch works when the counterweight strikes the lever.
Carry out the load test described in paragraph 5 and record the
rope replacement in Table 2.
8.1.2 PERIODICAL CHECKS
subjected to abnormal strain (twisting, bending, kinks
or abrasion).
Replace the rope in case of the faults indicated in fig. 12.
Every three months carefully inspect the entire rope and in
particular the ends, recording the results on the card in the
manual (Table 2), which must be kept by the site manager.

hole and slot.
Insert the new rope in the hole and
run it through the slot in the drum
tube. Tighten the clamp at the end,
leaving about 1 cm of rope free (fig.
5.1), then pull the rope until the clamp
touches the inside wall of the drum.
Wind on two complete turns of rope,
keeping the rope in contact with the
drum (fig. 5.2).

- Visually check the rope daily and whenever it is
- Replace the rope at least every year. .
