Working In Safety; General Description; Connection To The Mains - IMER TR 225 2V Operating, Maintenance, Spare Parts Manual

Dear Client
Congratulations on choosing the IMER hoist, 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 hoist.
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 ISO 12100-2) until the machine
is disposed of. If it is damaged or lost, a replacement copy may be
requested from the hoist manufacturer.
The manual contains the declaration of conformity CE 98/37/CE as
well as important information on site preparation, installation, use,
maintenance operations and how to request spare parts.
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 with particular reference to suspended loads
and fall equipment (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 or working parts of the
machine.
IMER INTERNATIONAL declines all responsibility for non-compliance
with laws and standards governing the use of lifting equipment, in
particular; unprogrammed 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.

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 on building construction sites.
- 2) Carrying passengers and/or animals is prohibited.
- 3) The machine must not be used in potentially explosive
atmospheres or underground.
The machine consists of (fig. 1):
Drum type winch fitted to reduction gear shaft (3), wire rope (1), lift
hook (2) and counterweight (10).
Gearmotor consisting of an electric brake motor (4) and oil bath
reduction gear unit (14).
Electrical system (5).
UP position control lever (9).
Rotary frame (6) with telescopic arm (7), loocking handle (8) and
frame locking lever (11).
DOWN position control lever (16).
- 1.5m. pendant control (low voltage 24V) with three
pushbuttons (15).
2. WINCH SUPPORTS
The structure supporting the winch must bear the stress generated
during operation (Fig. 2).
IMER offers a wide range of
supports (see figures 7-8-9-10-
11-12) for use on building sites,
designed to suitably transfer the
stresses to the building structures.
- WARNING: The EC
Declaration of Conformity
enclosed with this manual is
only valid if only IMER
components are used for the
winch and support.
If this condition is not complied with, the Declaration loses its
validity and the installation technician must compile a new
EC Declaration of Conformity after having satisfied all the
provisions of the Machinery Safety Directive 2006/42/CE.
These forces - referred to support couplings - must be accounted for
in calculations related to supporting structures (scaffolding, balconies,
ceilings, etc.), made by a qualified technician.

If the winch is to be secured to scaffolding, it must be adequately
protected from the wind (Fig. 13).
To install the various supports, follow the instructions applying to each
assembly.
When using supports with load bearing capacities other than that of
the hoist, the permissible load bearing capacity of the weakest element
of the system must be prominently displayed.
2.1 INSTALLING THE HOIST 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 can lean out into the hoistway from intermediate floors.
- Cordon off the ground loading area to prevent interference with
work.
3. ASSEMBLY (Fig.1)
1) Only competent, trained personnel may assemble and operate the
hoist.
Given the weight of the hoist, an appropriate number of personnel
must be used for handling and installing it so as to avoid hazardous
situations.
2) The maximum working height (50m) corresponds to the gearmotor
position i.e. is measured from the top hinge of the support.
3) Secure the support to the building and check the support pins
vertical alignment (12); then lift the locking lever (11) to insert the frame
bushings (6) onto the pins and fit the split pin retainer (13).
4) Fit the telescopic arm (7) to the frame (6) at its minimum extension,
screw on the locking handle and washer in the threaded hole through
its slot and tighten fully.
5) When assembling on a trestle support, fit the telescopic arm (7) to
the carriage through the securing holes (14) using bolts and locknuts.
For the rest, follow the instructions for the trestle support
6) Fix the remote-control and connect to switchboard.
All pendant controls have 3 pushbuttons (Fig. 3):
black: down
white: up
red: emergency stop.
7) 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 -10% to +6% of
the nominal operating value.
- The power cable must be fitted with an overload circuit breaker or
fuse and a RCCD ,the earth wire must have the same cross-section
as the power cable.
The conductors 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).
- Insert the plug into the machine and tighten the securing collar (IP67
protection).
- 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 hoist make sure that it has been correctly installed.
1) Lower the unloaded rope to the lower loading position, 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, UP limit switch
operation, correct rope winding onto the drum and motor brake
operation.
3) Load test. Load the hoist with its maximum admissible load.
Run a complete up/down cycle to test the stability of the supports and
the motor brake.
After the test, check the support structure for failure and slippage and
recheck the drum level (use a level as in Fig. 1).
