General Description - IMER AIRONE 300 N Manual De Uso & Mantenimiento

Dear Customer,
Congratulations on purchasing the IMER hoist: the result of
years of experience, it is an extremely reliable machine
featuring innovative technical solutions.
- WORKING SAFELY: For safety purposes, carefully
read the following instructions.
This OPERATION AND MAINTENANCE manual must be kept by
the site manager and be always available for consultation.
The manual is considered a part of the machine and must be
kept for future reference (EN 292/2) until scrapping of the
machine. If the manual becomes lost or damaged, request
another copy from the manufacturer.
The manual contains important information regarding site
preparation, installation, operation, maintenance and ordering
spare parts.
In any case, the installer and the operator must have adequate
experience and knowledge of the machine.
To guarantee the operator s safety, safe operation and long life
of the machine, follow the instructions in this manual and
observe the current regulations on safety and accident
prevention in the workplace (use of suitable footwear, clothing,
helmets and safety harnesses, arrangement of railings around
drops, etc.).
- Do not modify the metal structure or working parts
of the machine in any way.
IMER INTERNATIONAL declines any liability for non-compliance
with the laws on the use of hoisting equipment, and in particular:
improper use, faulty power supply, inadequate maintenance,
unauthorised modifications, tampering and/or damage and failure
to follow any or all of the instructions contained in this manual.

1. GENERAL DESCRIPTION

- Important: Using lifting equipment requires great
attention and skill, therefore the hoist must only be used
by expert or adequately trained personnel.
- 1) The machine is designed for lifting materials
and for use on building sites.
- 2) Do not use the machine for lifting people and/
or animals.
- 3) Do not use the machine in places with risk of
explosions or fire or in underground excavations.
The machine mainly consists of (fig.1):
- Drum (ref. 3) fitted on the reduction gear shaft, wire rope (ref.
1) that slides on a pulley (ref. 6), a lifting hook (ref. 2) and
counterweight (ref. 10).
- Gearmotor consisting of a self-braking electric motor (ref. 4)
and oil-bath reduction gear unit (ref. 14).
- Electrical panel (ref. 5).
- Up travel end control lever (ref. 9).
- Revolving frame (ref. 7) with rotation locking lever (ref. 11),
extensible arm (ref. 16) and two tie-rods (ref. 8).
- 1 m pendant control with three pushbuttons (ref. 15).
2. IMER HOIST SUPPORT STRUCTURES
The structure on which the hoist is mounted must be able to
withstand the stresses indicated in fig. 2, that are generated
during operation.
The 520 N force is perpendicular to that of 10850 N. Since the
hoist can rotate on the support pivots, these forces must be
checked in all possible positions of the hoist.
IMER INTERNATIONAL constructs the hoist frame, shown in fig.
7, for specific use on building sites and designed to suitably
transfer these stresses to the supporting structures.
- IMPORTANT. .
The EC declaration of conformity enclosed with this
manual is valid only if all components manufactured
by IMER are used (hoist and support structure).
If this condition is not met, the declaration is valid only
for the hoist.
The installer must draw up a new EC Declaration of
Conformity after verifying that all the requirements
IMER INTERNATIONAL S.p.A.
AIRONE 300 N
contained in the Machine Directive 98/37/EC have been
met for the hoist and support assembly.
The forces indicated at the support points (fig. 7) must be
considered in the support structures (scaffolding, balconies,
ceilings, etc.) check calculation made by a qualified technician.
When using supports with load capacity different from that of
the hoist, the permissible load capacity according to the weakest
element of the system must be clearly displayed on the equipment
assembly installed.
When installing the hoist frame, follow the instructions given in
par. 7.
2.1 PREPARING THE WORKPLACE
railing at least 1 m high and with a foot stop.
Make sure the lifting run is completely free from obstacles and
that no one can lean out from intermediate floors.
Cordon off the ground loading area to ensure that no one enters
it during lifting.
3. ASSEMBLY
1) The hoist must only be assembled and operated by skilled or
adequately trained personnel.
Given its weight, an adequate number of operators must be
used when the hoist is being transported and installed so as to
avoid creating hazardous situations.
2) The maximum work height (25 m) corresponds to the position
of the pulley axis (ref. 6) located at the end of the extensible
arm (ref. 16).
3) Fit the tie rods (ref. 8) connecting them to the frame (ref. 7)
and the extensible arm (ref.16) using the special nuts and bolts
present in the connection seats. Fit the washers D=12x36x4
mm as shown in fig. 3. Tighten the nuts. Make sure the Up limit
switch electric cable
(which is run through
the
extensible arm near
the hinge on the fra-
me) is not pulled or
jammed
mechanical parts.
4) Position the support
structure and check
the vertical alignment
of the support pins
(ref. 12), then lift the
locking lever (ref. 11),
insert the supporting
frame bushings (ref. 7) on the pins and fit the safety split pin
(ref. 13).
5) Adjust the length of the extensible arm (ref. 16) by means of
the adjustment holes and tightening the screw with nut.
The extensible arm allows a lifting travel
from the axis of the pins of between 85
and 110 cm.
6) Make sure all nuts are tight and check
the vertical alignment of the support pins
(ref. 12) with a spirit level to ensure that
the hoist is correctly positioned.
7) The hoist is equipped with a pendant
control with three pushbuttons (fig. 4):
black = down, white = up, red =
emergency stop.
8) Release the hook.
