Working In Safety; General Description; Connection To The Mains - IMER TR 225 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 292/2) 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 important information regarding site
preparation, installation, operation, maintenance, and ordering of
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 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).
DOWN position control lever (16).
Rotary frame (7) with telescopic arm (6), loocking handle (8) and
frame locking lever (11).
Thermal overload (17) which stops the winch when the current
exceeds the nominal value (press to reset).
The winch has two types of pendant control (15)
1.5 m lead direct pendant
25 m low voltage (24V) pendant.
30 m low voltage (24V) pendant.
2. WINCH SUPPORTS
The structure supporting the
winch must withstand the loads
generated during operation (Fig.
2). IMER offers a wide range of
supports (see figures 9-10-11-
12-13-14) for use on building
sites, designed to suitably
transfer the loads 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 is
applicable to the winch only. The installation technician who
fits the winch an another type of 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.
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, never fit it to a free
standing upright (Fig. 15).
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 (30m) 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 (7) onto the pins and fit the split pin retainer (13).
4) Fit the telescopic arm (6) to the frame (7) 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 (6)
to the carriage through the securing holes (14) using bolts and
locknuts. For the rest, follow the instructions for the trestle support.
6) Insert the direct pendant control (1.5 m lead) plug in the electrical
panel (5) and turn on the main switch
For the 24V low voltage pendant fix the electrical panel on the fra-
me (7) and insert the connector in the panel (5).
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 -5% to +5%
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. Make sure that any
extension cable connections are dry and safe.
- 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.
