Dear customer,
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 ISO 12100-2) 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,
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 explo-
sive atmospheres or underground.
lift hook (2) and counterweight (9).
- Gearmotor consisting of a self-braking electric motor (4) and an
oil-bath reduction gear unit (13).
- Electrical system (5).
- UP position control lever (8).
- Revolving frame (7) and a frame locking lever (10).
- 1 m pendant control with three pushbuttons (6).
2. IMER HOIST SUPPORT STRUCTURE
The structure on which the hoist is mounted must be able to

The 300 N force is perpendicular to the 4000 N force. Since the
hoist is able to rotate on the supporting hinges, these forces must

are used (hoist and support structures).
for the hoist.
The installer should compile a new EC declaration of con-
formity, after verifying all requirements stated in the Machi-
nery Directive 2006/42/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,
If the hoist is to be mounted on scaffolding, the latter must be
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
- The loading access area must be protected by a rail
at least 1 m high and with a foot stop.
- Make sure that the lifting run is free from obstacles and make
- Cordon off the ground loading area to ensure that no one enters
the area during lifting.
1) Only competent, trained personnel may assemble and operate
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 gear-
motor position, i.e. it is measured from the top hinge of the support.
3) Secure the support to the building and check the vertical ali-
gnment of the support pins (11), then lift the locking lever (10),
insert the frame bushings (7) onto the
4) When mounting on a trestle support,
secure the frame (7) to the carriage
through the securing holes (12) using
the screws and self-locking nuts. For the
rest of the installation procedure, follow
the instructions for the trestle support.
5) The pendant controls have three

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 to
235 V with the hoist operating at full load.
differential type protection devices and the earth wire must have
the same cross-section as the live wire. The wires must be sized
taking into account the operating currents and the length of the
line to avoid excessive voltage drops (see Table 1).
Do not use extension leads wound onto drums.
- The power supply cable must be suitable for frequent handling
and must have an abrasion-resistant sleeve (e.g. H07RN-F).
- Connect the machine's plug to a 16 Amp EEC socket with an
IP67 protection factor and tighten up the securing collar.
- The hoist is now ready for testing.
