Retrofitting is a term used to describe general refurbishment
operations on machinery such as equipment or complete test machines. It
involves all the systems of the machine and consists in structural operations
that also modify its appearance.
Retrofitting differs from restyling since
it also involves more challenging modifications on the plants and mechanical
parts. Some operations commonly performed during the retrofitting phase are the
inspection of hydraulic cylinders, the replacement or inspection of servo-valves,
replacement or inspection of hydraulic pumps, replacement of filters, recharge
of accumulators, replacement of flexible piping, inspection and calibration of
measuring instruments. Less common operations, which are, however, performed
during challenging retrofitting operations, can be the structural modification
of the frame and replacement of servo-control.
Retrofitting is a technique that allows to
significantly extend the service life of a machine and essentially obtaining a
brand new machine.

During the retrofitting very often all the
operations for the machine regulations are provided. In particular, we plan a
“ITALSIGMA PROTECT TESTING” SAFETY SYSTEM.
An electro-hydraulic system that activates
when the doors are opened, inserting a low pressure and low speed operation
mode of the cylinder to allow the operator to intervene even during the
specimen assembly.
The system includes perimeter protections
with doors and relative safety microswitches.
