Mechanical design

The C&G Engineering Service team monitors the evolution of production technologies and components in order to always provide the best solution.

Together with the customer, we immediately identify the objectives to be achieved and propose realistic and competitive solutions in all respects, organising all the various stages of the project in order to achieve maximum results, with particular attention to reducing costs.

In summary:
  1. identify and understand the client's needs
  2. propose the best solutions that meet the requirements;
  3. develop the project in a comprehensive manner with a turnkey solution;
  4. develop the project with the customer's technicians.

Completed projects

  • 80-tonne off-road crane.
  • Set design for La Scala mobile theatre in Milan.
  • Soyak Krystal sunroof.

FEM modelling - Kineto-dynamic analysis

For reducing production costs and improving performance. Through the use of structural calculation programs with finite elements, such as FEM/FEA analysis, optimised geometries are defined in the preliminary phase, which can allow a reduction in production costs and an improvement in performance.

The simulation of structural behaviour allows to reduce the number of preliminary tests on the building and to create optimised prototypes.

FEM/FEA (Finite Element Analysis) analysis not only makes it possible to know what stresses the part to be built will be able to withstand, but at the same time makes it possible to anticipate any problems that may arise. Through structural analysis, it is possible to simulate a specific event and trace the causes of unforeseen failure in order to act in advance on the safety of particular structures.

Safety of special equipment and installations

CE marking is the formal act by which the manufacturer certifies that he has fulfilled all the necessary requirements of the Machinery Directive and other important European directives applicable to the machine in general in order to make it safe to use.

  • Find out more

    The C&G Engineering Service team is involved in the global process with which the CE marking of a new machine is carried out, which requires:

    • creation of the Technical File
    • verifications and calculations;
    • risk analysis;
    • creation of the instruction manual;
    • tests and certifications
    • declaration of conformity. 

    The team also provides for the adaptation of existing machines to the criteria of the Machinery Directive for safe use and maintenance, which requires:


    • creation of the technical file
    • survey of the functions and the electrical diagram
    • survey of mechanics and carpentry;
    • checks and calculations;
    • risk analysis;
    • creation of the instruction manual;
    • tests and certifications;
    • declaration of conformity;
    • CE certification;
    • cryogenic plant in the food field;
    • certification of special pipe lifting hooks (load tests).
  • special equipment

 Metal and mechanical carpentry design

The load-bearing structure of an industrial building (shed, silo, hangar, warehouse) is built using profiles and other standardised steel products of suitable dimensions.

The design of the structure is then performed and the drawings for supply, workshop and assembly are drawn up, complete with estimates for materials and calculation reports.

  • Find out more

    C&G Engineering Service continues with the management of the project, following the fabrication of the carpentry and the various parts of the metal structure, as well as the control of the quality of the steels, the welds and the relevant certifications.

    The operation then continues with on-site assembly and the development of the project for assembly.


    In short, for metal carpentry we can provide:


    • overall executive drawings
    • workshop drawings
    • assembly drawings;
    • calculation report signed by a qualified technician;
    • estimated metric calculation;
    • works management;
    • testing or testing assistance.
