Original Instructions
2.2 Qualification
Transporting the hydraulic attachment is only permitted
if carried out by people who:
• are authorised to operate a crane or a forklift truck
according to the applicable national provisions,
• know all the relevant national/regional safety provi-
sions and accident prevention rules,
• have read and understood the safety and transport
chapter of these Safety and operating instructions.
Installing, maintaining, storing and disposing of the
hydraulic attachment are only permitted if carried out by
people who:
• know all the relevant national/regional safety provi-
sions and accident prevention rules,
• have read and understood these Safety and operat-
ing instructions.
Operating the hydraulic attachment is only permitted if
carried out by qualified carrier drivers. Carrier drivers are
qualified if they:
• have been trained to operate a carrier according to
the national regulations,
• know all the relevant national/regional safety provi-
sions and accident prevention rules,
• have read and understood these Safety and operat-
ing instructions.
Testing the hydraulic installation is only permitted if
carried out by professionals. Professionals are people
who are authorised to approve a hydraulic installation for
operation according to the national regulations.
Repairing the hydraulic attachment is only permitted if
carried out by professionals trained by Construction
Tools GmbH. These professionals must have read and
understood these Safety and operating instructions.
They must follow all safety instructions and guidelines
for repair. Otherwise the operational safety of the hy-
draulic attachment is not guaranteed.
2.3 Intended use
You may only use the Hydro Magnet for collecting and
separating ferro-magnetic materials.
Only attach the Hydro Magnet to a hydraulic carrier of a
suitable load−bearing capacity. Read the carrier manu-
facturer’s Safety and Operating instructions before at-
taching the Hydro Magnet to the carrier and operating it.
Observe all instructions.
Select the carrier and the lifting equipment so that they
are designed to handle the Hydro Magnet with it's maxi-
mum recommended load.
You must connect the Hydro Magnet to the carrier via an
adapter plate or a quick coupler. The suitability of the
adapter plate or the quick coupler must be considered in
the light of the maximum load.
The Hydro Magnet may only be operated when no per-
son is in the danger zone of 20meters (66ft) around the
Hydro Magnet. The danger zone of the Hydro Magnet
must be secured with a construction fence (height 2m
(6.6ft).
You may operate the Hydro Magnet at an ambient tem-
perature of -10°C to +50°C (14°F to 122°F).
Permitted Loads:
The loads must be ferro-magnetic. To determine the
load capacity of the magnet, a flat piece of low-carbon
iron and a predetermined air gap was used. For materi-
als that consist of more solid iron that are coated and
thus have a higher carbon content, the load capacity is
reduced.
Reduce your values by the relevant factor in the follow-
ing table:
0.9 for molten iron
0.8 for iron with 3% silicon
0.7 for iron type C60
0.45 for cast iron
The loads:
• shall be of such a form and dimension that an abso-
lute contact is guaranteed on the magnetic surface.
• must have a clean and flat surface so that no
greater air gap than that expected occurs.
• must not change their static condition during trans-
port, eg, thin and long loads must not bend.
If the Hydro Magnet is used for lifting of scrap, the scrap
weight plus the weight of the Hydro Magnet must not ex-
ceed the load capacity of the lifting equipment used
(ropes, chains, shackles, etc.), or the adapter plate or
quick coupler.
