VOKKERO GUARDIAN at FRANKI Fondation: freedom of movement and safety for field teams!

Back to the Grand Paris Express construction site, Metro Line 18, Palaiseau-Saclay.

The customer

French leader in deep foundation work, FRANKI Fondation offers a complete range of piles, supports and soil reinforcement techniques.

The pile is made using a hollow shaft auger screwed into the ground without any significant soil extraction. The auger is then extracted from the ground without unscrewing, while concrete is simultaneously injected through the auger’s hollow shaft.

The reinforcing cage is then installed.

The brief

The auger-digging team consists of 4 people, 3 of whom operate machines (drill, shovel, concrete pump).

The movement of pedestrians, pedestrian-engine co-activity and falls on the same level are dangerous situations that lead to production stoppages (estimated time in blind spots = 27 min/d) and sometimes collisions.

Communication is difficult and imprecise: horns honking, shouting, gestures, stress, misunderstanding.

The deployed solution

We deployed VOKKERO GUARDIAN equipment on the augering team to enable clear, instant communication in an environment where machine noise can reach 100 decibels.

The coverage provided by the VOKKERO GUARDIAN is also a major advantage for drill, shovel and concrete pump operators, who are sometimes several hundred meters apart.

The result

Hearing protection and clear communication

The VOKKERO GUARDIAN‘s noise filter ensures clear, intelligible communication between field teams.

A wide range of headsets and earpieces gives teams the choice of finding the right hearing protection for their needs.

Enhanced safety

Machine movement and lifting maneuvers are now safe thanks to constant communication, as if they were right next to each other.

Productivity improvement

The clear, fast and instantaneous communication enabled by the full-duplex functionality of the VOKKERO GUARDIAN system has improved the productivity of work teams, thanks to instantaneous exchanges that limit travel.

« The 1st benefit of the VOKKERO GUARDIAN is team cohesion, and the 2nd is safety. We communicate without gesturing. It gives us freedom to work, while remaining safe ».
