A residual risk is a hazard that cannot be completely eliminated through design and protective techniques
or a potential hazard that is not obvious.
Hazard: crushing/cutting limbs
Possibility/location of hazard
When assembling disassembling or performing
maintenance on the attachment there is a risk of
the attachment or part of it falling, or of sudden
movement of part of the attachment.
Protections/precautions
Such operations must be carried out carefully by
trained personnel. Wear suitable P.P.E.
Hazard: ejected oil
Possibility/location of hazard
When assembling/disassembling or performing
maintenance on the hydraulic components of the
attachment there is a risk that oil may ejected as a
result of residual pressure.
Protections/precautions
De-pressurise the circuit fully as shown in this
manual. Such operations must be carried out
carefully by trained personnel. Wear eye protection.
3.10.Placement of accident prevention plates and labels
The position of the accident prevention plates may vary depending on the model of the attachment.
3.11. Lighting
Lighting in the work area must conform to applicable legislation law in the country where the attachment is
being used and must provide good visibility at every point, not create dangerous reflections and allow for
clear visibility of the controls and the entire work area up to the safety limits required for objects that may
be ejected. Since the attachment has no independent lighting, the environment must be provided with
general lighting of 250 to 400 lux at every point in the work area.

4. Description of the attachment
4.1.Description of the attachment
The MK Series Multiprocessorr is an attachment that has been designed and constructed by Hydraram. It
is a functional and versatile attachment designed to handle a variety of work (demolition, crushing, cutting
scrap and metal profiles). The attachment consists of a main body and the jaws. There are 6 types of jaws.
Pulverizer kit: used to reduce cement elements and separate the rebar from the cement.
Shear kit: used on job sites and in industrial demolition depots to cut ferrous materials such as profiles,
plates and pipes.
Combi kit: for demolitions of structures made of reinforced cement with a high percentage of ferrous
materials.
Universal Kit: for controlled demolition of concrete structures and for the immediate reduction of rod
armor during the crushing of the concrete.
Tankshear Kit: indicated in construction sites and in stores for the demolition industry for cutting ferrous
materials such as steel and tanks.
Demolition kit: Is designed for primary demolition phases of most precision, as indicated for the demolition
of concrete structures and the removal of materials at relevant heights.
Various types of jaws (kits) are available that can be interchanged on the same body. The body is fitted
with a slew ring for continuous hydraulic rotation, so as to reduce moving operations as much as possible
and provide the highest level of precision.
The closing force is produced by a hydraulic cylinder, which enables the device to demolish even the
most resistant materials. The body and various types of kits are made from wear-resistant steel with
high elasticity. This ensures excellent anti-abrasion characteristics together with exceptional mechanical
strength.
The hinges are made of thermally-treated steel alloy and rotate on hardened, ground bushings with
grooves for internal lubrication.
Kits with an interchangeable teeth and blade system ensures they can be replaced quickly and directly on
site, thus avoiding having to repair worn parts reducing maintenance costs and limiting machine downtime.
4.2. Permitted enviromental conditions
The attachment is suitable for operating in environments that are:
• At altitudes no higher than 3,000m above sea level;
• At temperatures between -20 °C and +50 °C with an average temperature of about 25°C;
• At relative humidity between 30% and 95%.
