DIGILIFE

  • DIGILIFE : QUICK REMINDER

 

Aquass has been carrying out fatigue diagnostics on lifting equipment for more than 20 years. Our expertise has allowed assessing the state of fatigue and conservation of a very large number of lifting devices in operations at port terminals for instance. We recommended the controls necessary to keep them in service safely; we also developed optimized control plans on new or existing crane, after modelling their structures. DIGILIFE incorporates all of our “know-how”.                                    

Aquass has been designing and developing DIGILIFE for over twenty years. We have therefore tested it, from installation to operation, on more than 100 cranes that are equipped with it and on which DIGILIFE monitors day after day.

We were thus able to select and develop its functionalities depending on their technical value to make our product more reliable.

Today, DIGILIFE is the only product with such fatigue supervision functions and feedback.

 

  • AQUASS’ EXPERTISE IN THE HEART OF THE SYSTEM

 

DIGILIFE is an intelligent on-board system, which continuously analyzes the activity of a lifting equipment in order to know in real time its state of fatigue, based on a conventional designed limit. Its presence traces the life of the crane, and makes it possible to anticipate its future.

The cranes typically concerned are gantry cranes for containers and bulk, quay cranes, overhead cranes and multiple special machines subject to fatigue.

DIGILIFEPLUS

 

  • FROM THE WHOLE STRUCTURE …. TO EACH ASSEMBLY

DIGILIFE main function in terms of fatigue compares in real time the aging of the crane as a whole and of its kinematic chains with the overall conventional fatigue expected by the manufacturer during its design.

The aging of the crane as a whole is essential, but in order to be even more relevant, attention must be paid to the aging of each welded assembly constituting its structure. Thus, controls are better targeted and better anticipated.

DIGILIFEPLUS now makes it possible to process the residual life of welds identified as critical, by comparing their maximum calculated real life and the life consumed according to the usual supervision in real time.

 

  • 3D MODELLING : BASIS OF THIS NEW ANALYSIS

Modelling, which is one of Aquass' specialties, makes it possible to define for each cycle, the extreme stresses and the stress spectrum factor of each assembly depending on the load. Aquass can therefore calculate the fatigue damage generated by each cycle, for each assembly.

DIGILIFEPLUS integrates the 3D modelling post treatment results, for calculating the residual life and the fatigue index of each assembly monitored.

 

  • DIGILIFEPLUSOPTIMIZES THE CONTROL PLAN

Knowing these residual lifetimes in real time and on demand allows DIGILIFEPLUS to optimize the structure control plan established by Aquass, and to improve its relevance in terms of safety, taking into account the value of the actual fatigue index of each assembly identified as critical.

DIGILIFEPLUS becomes a management tool for the maintenance of structures, by establishing a reasonable and optimized control plan as it is based on the analysis of the real risks associated with fatigue damage.

Insurers being more and more sensitive to the conditions of organization and rigor for carrying out maintenance operations, especially after damage, this type of approach is likely to reassure them.

 

  • DIGILIFE AND DIGILIFEPLUS FUNCTIONS                                            

DIGILIFE provides the aging of the crane and of the kinematic chains as a whole, the useful values such as load and outreach spectra, and exceptional load values, as well as the recording of the values of many monitored parameters during a dysfunction of the hoist or during an incident.

DIGILIFEPLUS adds the possibility to obtain the values of the residual lifetimes and fatigue index of specific assemblies, and the establishment of a control plan according to the actual aging of the assemblies.
