The Petra System

Petra® Software is a network of products that brings together powerful and reliable calculation systems that help to assess and manage the risks of biomechanical overload of the spine and upper limbs.


in managing the risk data relating to the individual workstations and their aggregations (the risk maps of the stations, by line, area, department, and company)

in managing risk data relating to individual operators and collectives (personal exhibition data and workers' exhibition maps)

in managing video documents (work archive), it is possible to archive the videos, organize them logically by linking them to the company organization chart (archive of the homework videos). The analysis of the film is performed within Petra® with these possibilities:

  • management also by segments or phases
  • calculation of the desired times and use within the various storage calculation modules
  • archiving of the necessary movie segments
in managing the final evaluation documents and the printouts, Petra® is able to print on MS Word compatible printing modules and completely customizable by the user (it does not require the presence of Microsoft Office® on the computer). Backup and recovery utilities give Petra® stability and security in data storage.






Flow of information in a continuous cycle between the health service and the technical services responsible for risk assessment.


The Petra ® System (which is born with multi-company features) allows the management of company data and personal data of individual workers (input data necessary for the assessment of the actual risk) in a simple and fast way.

In fact, with the insertion of both the workers' registry and the company organization chart (automatic with Alfagest®) it is possible to create a real risk map (of the exhibits) combining "by simple dragging" to the groups of stations (homogeneous by risk), the names of the workers who work in them (identification of homogeneous groups by exposure).

It follows that each employee can be connected (and updated in real time) his own risk index taking into account the turn-over. It is also possible to produce print reports that summarize the data collected at the level of a single task, a workstation, a single operator, a homogeneous group, maps, etc.
