We have come a long way, but after more
than fifty years our course is still market by the
desire to achieve quality and innovation so
that we can live up to our permanent
commitment to improvement.
We maintain our innovative spirit, high standards
of quality and strict checks of material and
processes. We are making our tools more
powerful, safer, more operative and longer
lasting.
Thus we place our experience in your hands.
The high reputation of MEGA
abroad has enabled us to
consolidate a firm position on
the markets of all five
continents.

Read carefully the safety, user and
maintenance instructions provided with
the equipment. If these basic rules are not
followed injury to the user, the hydraulic
equipment or the load to be lifted may
result.
Position the cylinder on a solid, even
and horizontal surface.
Never use the cylinder on a slope.
Keep a safe distance from the load
during operation.
Never position any part of your body under
the load.
Always secure the load with mechanical
stands.
Clean couplers before connecting and make
sure the connections are securely tightened.
Never exceed the rated capacity of the
cylinder.
It is strongly recommended the use of a
gauge to check the pressure.
Prevent hoses from sharp bending and do
not drop objects on them.
Never disconnect couplers unless the piston
is fully retracted.
Always use a safety cock to block the cylinder.
Avoid extreme heat and temperatures over
65ºC .
Never use cylinders without a saddle.
The saddle helps centre the load.
Never use excessive tightening force that
may damage the fittings. Do not use tools.
Never use extensions on hand pumps or jacks.
Use only the lever provided.
Always use a cylinder of a capacity and hydraulic stroke 25% higher than
the weight of the load to be lifted.
Use original MEGA oil.
IMPORTANT. An excess of oil will render the
pump inoperative.
VERY IMPORTANT.- Never use brake fluid.
After use, retract the piston completely, clean
the equipment and keep it protected from
aggressive environment.
Repair kits are available for every item in this
calalogue.
Always indicate the reference of the item for
which the kit is intended.
A basic hydraulic configuration consists of a single-acting cylinder, a pump
and a hose. It is really a small machine with the following components:
a) Flow generator = Pump. b) Flexible hose to transmit the oil flow from pump
to cylinder. c) Hydraulic cylinder, consisting of a chamber with inlet for the
oil and a piston to retain the oil and maintain the pressure that raises or
lowers as the oil changes within the chamber. The pressure is
created by resistance to flow. This resistance is the result
of a load. This hydraulic equipment can be used in
virtually all types of industry. From a basic pump
and cylinder set, you can build many
different system configurations by
adding components and
accessories.

Working pressure: 700 kg/cm2/10.000 psi.
All pistons have a salt bath nitriding treatment
or a hard chrome plating, depending on the
model, to resist corrosion and for longer life.
With built-in bronze guide for easier sliding
of piston.
These cylinders are fitted with a removable
grooved saddle, pressure mounted or screwed
in the piston head. They are also equipped
with a high flow female quick coupler with
dust cap, ref. A-5507-H.
Carry handles on models weighing from
20 kg/44 lbs to 40 kg/88 lbs. Heavier models
are fitted with eye hooks for transport.
With mounting holes and threaded areas
protected against blows for easy coupling or
special tooling applications.

easy coupling or special tooling applications.
Unlike the pushing cylinders, the pulling
rams retract toward the base to apply
pressure.
These pushing and pulling cylinders can
be original components of the Maintenance
