Imer Group TR 225 N Handbuch Für Bedienung, Wartung Und Ersatzteile Seite 11

Dear customer,
Congratulations on purchasing an IMER hoist, a reliable and
innovative product created through years of experience.
- WORKING IN SAFETY: The following instructions
are essential for safety.
This OPERATING AND MAINTENANCE manual must be kept on
site by the foreman and must be accessible for consultation at
all times.
The manual is be considered an integral part of the machine
and must be kept for future reference (EN 292/2) until the
machine is scrapped. If it is damaged or lost, a replacement
copy can be requested from the hoist manufacturer.
The manual contains important information on site preparation,
installation, operation, maintenance and ordering of spare parts.
The installer and operator must have adequate experience and
knowledge of the machine.
To guarantee complete safety of the operator, safe operation
and a long service life, follow the instructions in this manual
and observe current applicable legislation regarding safety and
accident prevention in the workplace (use of suitable footwear,
clothing, hard hats and safety harnesses, proper installation of
railings around drops, etc.).
- It is strictly forbidden to modify the steel structure
or working parts of the machine in any way.
IMER INTERNATIONAL will accept no responsibility for failure to
comply with legislation and standards governing the use of
hoisting equipment, in particular: improper use, incorrect power
supply, inadequate maintenance, unauthorised modifications,
tampering and/or damage and partial or complete 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
- Warning: Use of lifting equipment requires great
skill and care. The hoist must be used by skilled and
properly instructed personnel only.
- 1) The machine is designed exclusively for lifting
materials and for use on building sites.
- 2) The machine must not be used for lifting people
and/or animals.
- 3) The machine must not be used in potentially
explosive atmospheres or underground.
The machine consists essentially of (fig. 1):
- Drum type winch fitted to reduction gear shaft (3), wire rope
(1), lift hook (2) and counterweight (10).
- Gearmotor consisting of a self-braking electric motor (4) and
an oil-bath reduction gear unit (14).
- Electrical system (5).
- UP position control lever (9).
- DOWN position control lever (17).
- Rotary frame (7) with telescopic arm (6), loocking handle (8) and
frame locking lever (11).
- Thermal overload (16) which stops the winch when the current
exceeds the nominal value (press to reset).
- The winch has three types of pendant control (15)
1.5 m lead direct pendant
5 m lead direct pendant
30 m low voltage (24V) pendant.
2. IMER HOIST SUPPORT STRUCTURE
The structure on which the hoist is mounted must be able to
withstand the stresses generated during operation (fig. 2).
The 400 N force is perpendicular to the 5000 N force. Since the
hoist is able to rotate on the supporting hinges, these forces
must be verified in all possible positions of the hoist.
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.
IMER INTERNATIONAL S.p.A.
TR 225 N
The EC declaration
of
enclosed with this
manual
only if components
m a n u f a c t u r e d
exclusively by IMER
are used (hoist and
support structures).
If this condition is
not satisfied, this
declaration is valid
only for the hoist.
The
should compile a new EC declaration of conformity,
after verifying all requirements stated in the Machinery
Directive 98/37/EC for the equipment and support
assembly.
The forces on the support couplings must be accounted for in
calculations for the supporting structures (scaffolding,
balconies, ceilings, etc.) made by a qualified technician.
If the hoist is to be mounted on scaffolding, the latter must be
adequately braced against wind (see fig. 13).
Follow the instructions provided for installation of the various
supports.
If supports with different capacities from the hoist are used,
the permissible capacity of the weakest element in the system
must be marked on the assembly in a clearly visible position.
2.1 PREPARING THE WORKPLACE
rail at least 1 m high and with a foot stop.
- Make sure that the lifting run is free from obstacles and make
sure that no one can lean out from intermediate floors.
- Cordon off the ground loading area to ensure that no one
enters the area during lifting.
3. MOUNTING THE HOIST (fig. 1)
1) Only competent, trained personnel may assemble and ope-
rate the hoist.
Given the weight of the hoist, it must be transported and installed
by an adequate number of operators to avoid hazardous
situations.
2) The maximum working height (30 m) corresponds to the
gearmotor position, i.e. it 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) Ensure that the hoist is completely level by means of a spirit
level placed on the top plate of the drum. (fig. 1).
6) The telescopic arm (6) allows a lifting excursion from the
axis of the pins of between 720 and 1120 mm.
7) When assembling on a trestle support, fit the telescopic arm (6) to
the carriage through the securing holes (fig. 12) using bolts and
locknuts. For the rest, follow the instructions for the trestle support.
5) Insert the direct pendant control (1.5 or 5 m lead) plug in the
electrical panel (5) and hook the spring clip of the steel cable onto
the ring on the electric panel to avoid pull on the electric cable.
For the 24V low voltage pendant fix the electrical panel on the frame
(7) and insert the connector in the panel (5).
All pendant controls have 3 pushbuttons
(Fig. 3):
black: down
white: up
red: emergency stop.
6) Release the hook.
4. CONNECTION TO THE ELECTRICITY MAINS
- Make sure that the mains voltage corresponds to the rating on
the machine s rating plate.
- Also ensure that the mains voltage is within the range 210 V
