Dear Customer, Congratulations on your choice of purchase:
IMER hoists are the result of years of experience and are
equipped with all the latest technical innovations.
WORKING IN SAFETY: to work in complete safety, read
the following instructions carefully.
This OPERATION AND MAINTENANCE manual must be kept on
site by the person in charge and must always be available for
consultation.
The manual is to be considered integral part of the machine and
must be kept for future reference (EN 292/2) until the machine is
disposed of. If the manual is damaged or lost, a replacement may
be requested from the hoist manufacturer.
The manual contains important information regarding site
preparation, machine use, maintenance procedures, and
requests for spare parts. Nevertheless, the installer and the
operator must both have adequate experience and knowledge
of the machine prior to use.
To guarantee complete safety of the operator, safe operation
and long life of equipment, follow the instructions in this manual
carefully, and observe all safety standards currently in force for
the prevention of accidents at work (use of suitable footwear
and clothing, helmets, safety harnesses, installation of adequate
railings around voids, etc.);
It is strictly forbidden to carry out any form of
modification to the steel structure or working parts of
the machine.
IMER INTERNATIONAL declines all responsibility for non-
compliance with laws and standards governing the use of this
equipment, in particular: improper use, defective power supply,
lack of maintenance, unauthorised modifications, tampering and/
or damage and partial or total failure to observe the instructions
contained in this manual.
1.GENERAL DESCRIPTION
Warning: The hoist must be operated by qualified
personnel only who must be familiar with all relative
instructions and proceed with caution.
1) The hoist is designed for lifting material and for use
on construction sites.
2) Use of the hoist to lift persons and/or animals is strictly
forbidden.
3) Never use the hoist in environments subject to the risk
of explosion or fire or in underground sites.
The standard hoist comprises (fig.1):
- Drum-type winch comprising drum (ref.3) mounted on reduction
gear shaft (ref.12), wire rope (ref.1), lifting hook (ref.2) and
counterweight (ref.9).
- Reduction unit comprising brake motor (ref.4) and oil-bath
lubricated reduction gear (ref.12).
- Electrical installation (ref.5) with pendant control unit (ref.7).
- Limit switch lever (ref.8)
- Load bearing frame (ref.6)
2. HOIST BRACKETS
The hoist bracket must have adequate tolerance to load stress
generated during operation as indicated in fig.4.
There is a vast range of brackets available, as shown in the
relative figures6, 7, 8, 10, 11, and 12 for various applications on
construction sites and designed to transmit relative loads to the
supporting structure.
The force applied on the bracket clamp points must be taken into
account for load calculations during inspections (scaffolding,
balconies, ceilings etc.). Inspections must be carried out by a
qualified technician.
In the case of hoist application on scaffolding, ensure
that suitable bracing is installed (see fig.9)
For bracket installation, follow the relative instructions supplied.
If bracket capacities differ from that of the hoist, affix a sign
indicating admissible capacity in relation to the most critical element
IMER INTERNATIONAL S.p.A.
ES 150 (110V/50Hz)
of the system.
The opening side for access to the loading area must be protected
with railings at least 1 m high and a toe guard.
Ensure that the lifting area is unobstructed throughout the entire
height and take necessary precautions to ensure that no person
can lean out of intermediate floors.
Ensure delimitation of the lower loading surface to impede access
during lifting operations.
3. ASSEMBLY (fig.1)
1) Assembly must be carried out exclusively by qualified
personnel who must be supplied with all the relative assembly
instructions.
Given the weight of the hoist, ensure that the number of operators
assigned for assembly is sufficient to ensure complete safety
during transport and installation.
2) Maximum working height (25 m) is measured from the ground
and the reduction unit to the upper clamp of the bracket.
3) Fit clamps onto the building support and ensure vertical
alignment of pins (10). Insert the bracket bushings onto the pins
and fit the washer and safety cotter pin (11) on the upper clamp.
4) In the case of hoist gantry assembly, secure the gantry by
means of the pre-drilled holes (fig.12) using the self-locking
screws and nuts supplied with the unit. Follow the relative
instructions supplied with the
gantry.
5) Release the hook
The hoist is fitted with a 3-
button pendant control (fig.2):
black = descent; white =
ascent, red = emergency stop
4. ELECTRICAL CONNECTION
- Check that the voltage corresponds to rating plate indications.
- Check also that mains voltage is between +/- 5% of the rated
value.
- Ensure that the electric power cable is fitted with an overload
cutout device, and that the earthing cable is the same size as the
mains cable. Cable dimensions must be commensurate with the
requirements for start-up currents and cable lengths to avoid
excessive voltage drops (see table 1).
- Do not use extension leads wound onto storage reels.
- The mains cable must be suited to frequent movement and
feature wear-resistant sheathing (e.g. H07RN-F).
- Connect the plug (IP67 protection category) to the machine by
tightening the lock ring.
- Proceed with preliminary testing after the above procedure.
5. TESTING INSTRUCTIONS
- WARNING!! This test must be carried out by qualified
staff and all safety precautions must be observed.
- WARNING
the hoist.
Before testing the hoist check that installation has been carried
out correctly.
1) Lower the rope under no-load conditions by pressing the
descent pushbutton, until it reaches the lower loading surface.
Ensure that at the end of travel at least three rope turns remain
wound on the drum.
2) No-load cycle test: Apply a small load (20 kg) and check that
the machine functions correctly by performing a complete ascent
and descent cycle. Test the following: ascent and descent control
pushbuttons, emergency pushbutton, ascent limit switch
intervention, correct winding of the rope onto the drum and
braking efficiency.
3) Load test: This test must be carried out by applying the
maximum specified load on the hoist. Carry out a complete ascent-
descent cycle and check hoist anchoring and braking system
efficiency. After testing, ensure that there are no signs of yield
or bedding in and repeat the horizontal alignment check on the
drum (use spirit level as shown in figure 1).
