IMER BOOSTER 15 Operation, Maintenance And Spare Parts Manual page 32

Dear Customer,
compliments on your purchase: the IMER concrete pump, resulting from
years of research, offers maximum reliability and features innovative
technical solutions.
- WORKING IN SAFETY.
For safety purposes, make sure to carefully read the fol-
lowing instructions, as well as the instructions given in the
enclosed manuals relevant to the compressor and the Diesel
engine.
This OPERATION AND MAINTENANCE MANUAL must be kept
by the firm's manager at the worksite, and be always available for
consultation, together with the user's manuals for the compressor
and the Diesel engine.
The manual is considered part of the machine and must be stored
for future reference ( EN ISO 12100-2 ) through to scrapping of the
machine itself. Should the manual be lost or damaged, a replace-
ment copy can be ordered from the manufacturer.
The manual contains the EC declaration of conformity
(2006/42/EC) important information on worksite preparation, instal-
lation, use, maintenance and ordering spare parts. Nevertheless,
the user must both have adequate experience and knowledge of
the machine prior to use: the user should be trained by a person
totally familiar with the operation and use of this machine.
To guarantee the operator's safety, safe operation and long life of
the machine, the instructions in this manual must be observed,
together with the current regulations on safety and accident-pre-
vention at work (use of adequate footwear, clothing, dust masks,
gloves, glasses, etc.).
- Make sure that all signs are legible.
- Do not make any modifications to the metal structure
or systems of the concrete pump.
- Always work with the casing closed.
Pay attention when opening the casing: on the inside
there are very hot parts (in particular, engine, compressor,
radiator), moving parts (alternator, motor fan, compressor
flywheel) and there may be traces of harmful liquids (in
particular, battery acid).
- Check the perfect efficiency of the safety devices,
and in particular the emergency button and the devices for
stopping mixer and agitator in case of opening of the grill and
mixer material door and hopper grill.
IMER INTERNATIONAL declines any liability in case of improper
use, feed defects, lack of maintenance, unauthorised modifica-
tions, and partial or total non-compliance with the instructions
contained in this manual.
1. TECHNICAL DATA
Table 1 gives the technical specifications of the concrete pump,
with reference to figure 1.
2. DESIGN AND CONSTRUCTION STANDARDS
The pumps are designed and built in accordance with the stand-
ards given in table 1.
3. NOISE EMISSION LEVEL
Table 1 gives the sound pressure levels of the pump measured at
the operator's ear (LpA at 1 m - 2006/42/EC) and the noise level
in the environment (power LWA) measured according to EN ISO
3744 (2000/14/EC).
4. DESCRIPTION OF OPERATION OF CONCRETE PUMP
- THE CONCRETE PUMP is designed for use on building
sites, for pumping concrete. The mixtures in use must be
pumpable: aggregate granulometry (e.g.: 45% 0-4mm, 10%
4-8mm, 45% 8-16mm) and consistence class (e.g.: fluid, slump
16-22 cm) suited to pumping.
IMER INTERNATIONAL S.p.A.
4.1 DESCRIPTION OF CONCRETE PUMP (see fig. 1)
The pump has the following major parts:
- A pumping unit composed of two concrete pumping pipes (Page
2 Ref. 1) housing the pumping pistons (Page 2 Ref. 2) which are
driven by hydraulic cylinders (Page 2 Ref. 3), a lubricant tank
(Page 2 Ref. 4), an S valve (Page 2 Ref. 5) driven by two hydraulic
switching cylinders (Page 2 Ref. 6), a lower hopper (Page 2 Ref.
7) with mixer (Page 2 Ref. 8) driven by a hydraulic motor and
material delivery flange (Page 2 Ref. 9), an upper hopper (Page 2
Ref. 10) with grill (Page 2 Ref. 11) to which is mounted a vibrator
(Page 2 Ref. 12)
- A hydraulic circuit, which including the above mentioned
cylinders, is composed of a variable rate pump (Page 2 Ref. 13)
driven by a diesel engine (Page 2 Ref. 14), and pumping and
switching valve block (Page 2 Ref. 15), and auxiliary pump (Page
2 Ref. 16) and an auxiliary manifold (Page 2 Ref. 17), a fluid
reservoir (Page 2 Ref. 18) with suction and return filters, a heat
exchanger (Page 2 Ref. 19)
- A control panel (Page 2 Ref. 20) with cabled remote control
(Page 2 Ref. 21) and radio control (Page 2 Ref. 22) (optional).
- A supporting chassis (Page 2 Ref. 23), a casing (Page 2 Ref.
24), a frame with wheels (Page 2 Ref. 25), available both in road-
towable and on-site versions.
- Accessory equipment such as various diameters of steel or
rubber delivery pipes, collars and gaskets, reducers from one
diameter to another, and cleaning sponges and other materials.
- Accessories like the set accelerant pump (Page 2 Ref. 26),
automatic greasing system (Page 2 Ref. 27), hydraulically
controlled water cleaner (Page 2 Ref. 28), Spritz Beton jet (Page
2 Ref. 29).
5. GENERAL SAFETY WARNINGS
- Before using the concrete pump make sure the protec-
tion devices have not been removed. Check the following
safety devices:
- Opening the grill on the upper hopper should stop the mixer
in the lower hopper, the S valve and the pumping pistons by
tripping the sensor (Fig. 1 Ref. 1).
- Pressing the emergency button (Fig. 2 Ref. 1) should stop
the machine.
- the hopper drain hatch (Fig. 3 Ref. 1) should be closed and
locked.
- The moving parts guard, tank guard and engine fan guard -
must be present and securely mounted;
- The upper hopper must be closed and locked;
- The casing must be closed by key during use.
Furthermore:
- Make sure the material delivery flange fitting is in perfect
condition;
- Check the condition of the pipes and the tightness of the
couplings, both when setting up the line and placing the
column and before starting any pumping. The pipes must
be correctly secured, using brackets if necessary (e.g. Fig. 4
Ref. 1) .
- The terminal (pipe or jet) must NEVER be directed at other
persons or oneself
- Before disconnecting the pipelines, ensure that the
pressure gauge reads zero (Fig. 2 Ref. 2);
