Dear Client
Congratulations on choosing the IMER winch, the reliable and
innovative result of years of experience.
WORKING IN SAFETY
To work in complete safety, read the following instructions
carefully before installing the machine.
This OPERATION AND MAINTENANCE manual must be kept on site
by the person in charge, e.g. the site foreman, and must always be
available for consultation.
The manual is to be considered an integral part of the machine and
must be kept for future reference (EN 292/2) until the machine is
disposed of. If it is damaged or lost, a replacement copy may be
requested from the manufacturer.
The manual contains important information regarding site preparation,
installation, operation, maintenance, and ordering spare parts.
Nevertheless, the installer and the operator must both have adequate
experience and knowledge of the machine prior to use.
To guarantee the 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, hard hats,
safety harnesses, proper installation of railings around drops, etc.).
It is strictly forbidden to carry out any form of modification
to the steel structure, working parts of the machine or the
gantry structure.
IMER INTERNATIONAL declines all responsibility for non-compliance
with laws and standards governing the use of lifting equipment, in
particular; improper use, defective power supply, lack of maintenance,
unauthorised modifications, tampering with or damage to part or all of
the equipment, and partial or total failure to observe the instructions
contained in this manual.
IMER INTERNATIONAL reserves the right to modify the
characteristics of the hoist and/or the contents of this
manual without any obligation to update previous machines
or manuals.
1. GENERAL DESCRIPTION
ATTENTION: Use of lifting equipment requires care and skill.
The machine must be operated by skilled and properly
instructed personnel only.
1) The machine is designed to lift materials only and for
use in building construction sites.
2) Carrying persons and/or animals is prohibited.
3) The machine must not be used in potentially explosive
atmospheres or underground.
The machine consists of (fig. 1):
- frame (ref. 6) with hand brake (ref. 8).
- Drum (ref. 3) fitted to reduction gearbox shaft (ref. 11), steel rope
(ref. 1) lift hook (ref. 2) and counterweight (ref. 10);
- Gearmotor consisting of an electric brake motor (ref. 4) and oil
reduction gearbox (ref. 11).
- Up position control lever (ref. 9).
- Electrical system (ref. 5), pendant control with three pushbuttons
(ref. 12) and flying socket (ref. 13).
2. IMER HOIST SUPPORT STRUCTURE
The structure supporting the winch must withstand the loads generated
during operation (Fig. 2).
IMER supplies a gantry support, as
shown in fig. 7, for use on building sites
and specially designed to transfer loads
to the load support structure.
ATTENTION
The EC Declaration
Conformity enclosed with the
present manual is only valid if
only IMER components are
used for the winch and gantry.
IMER INTERNATIONAL S.p.A.
ET 300 (110 V/50 Hz)
of
Fig. 2
If this condition is not complied with, the Declaration is
applicable to the winch only. The installation technician
who fits the winch on another type of gantry support must
compile a new EC Declaration of Conformity after having
satisfied all the provisions of the Machinery Safety Directive
89/392/EEC and its subsequent modifications and
supplements.
The forces - referred to support gantry - must be accounted for in
calculations related to supporting structures (scaffolding, balconies,
ceilings, etc.), made by a qualified technician.
When using supports with load capacities other than that of the winch,
the permissible load capacity of the weakest element of the system
must be prominently displayed.
2.1 INSTALLING THE WINCH ON SITE
The load access to the floor must be protected by a rail
over 1m high and a foot stop.
- Make sure that the lifting run is free from obstacles, and ensure that
nobody leans outwards on intermediate floors.
- Cordon off the ground loading area to prevent interference with work.
3. ASSEMBLY (Fig.1)
Only competent, trained personnel may assemble and operate the
winch.
Given the weight of the winch, an appropriate number of personnel
must be used for handling and installing it so as to avoid hazardous
situations.
The maximum working height (25m) corresponds to the gearmotor
position i.e. is measured from the gantry rails supporting the winch
(ref. 7).
Mount the winch on the gantry support by inserting the wheels (ref. 7,
fig. 1) in the rail guides (fig. 7) and release the brake (ref. 8, fig. 1).
Prevent detachment of the winch by fitting the end stop onto the rail.
Follow the rest of the instructions
as described in para. 7.
All pendant controls have 3
pushbuttons (Fig. 3):
black: down
white: up
red: emergency stop.
Release the hook.
4. CONNECTION TO THE MAINS
- Make sure that the mains voltage is the same as that specified on
the dataplate.
- Also check that the mains voltage is within the range -5% to +5% of
the nominal voltage, when lifting at the rated load.
- The power cable must be fitted with a magnetotermic switch and a
residual current device (rcd); the earthing wire must have the same
cross-section as the power cable.
Cables must be dimensioned in proportion to both the operating current
and their length to avoid voltage drops (Table 1).
Do not use extension leads wound on drums.
- The power cable must be suitable for frequent handling and have an
abrasion-resistant sleeve (for example H07RN-F).
Connect the machine s plug to a 32 Amp EEC socket with an IP67
protection factor and tighten up the securing collar.
- The hoist is now ready for testing.
5. TESTING
Warning! Testing must be carried out by qualified
personnel. Take all necessary safety precautions.
Warning! The winch must be tested before use.
Before testing the winch make sure that it has been correctly
installed.
1) Lower the unloaded rope to the lower loading position by means of
the descent pushbutton, and check that at the end of its travel three
turns of rope remain on the drum.
2) No-load test. Apply a small load (20 kg) and run a complete up/
down cycle.
Test the up, down and emergency stop buttons on the pendant control,
