Advanced ergonomic aids: never again strength to tighten
The new cartesian BC25 PK arm with advanced assistance, designed and manufactured by Fiam, represents the latest frontier in innovation for increasingly ergonomic tightening stations.
This model, which can be used with lever start air screwdrivers with pneumatic signal or lever start electric screwdrivers, is equipped with a special adjustable pneumatic push regulator that represents an extraordinary aid for the operator who can take advantage, during the tightening phases, of an automatic downward thrust and therefore must not use force to tighten.
This pneumatic thrust is also "double-acting": in addition to the automatic downward movement, which is activated simultaneously with the start of the screwdriver through the lever, when the tightening is completed and so when the lever is released, the arm and the screwdriver automatically return to the rest position, ready for a new tightening.
The pneumatic thrust can vary from 3 to 9 kg and the BC25 PK arm is the only one on the market equipped with a regulator of this important functionality: through the practical device equipped with an operating pressure indicator and placed on the arm it is possible to set the force of the thrust based on the type of screw used and the junction. A great advantage for the quality of the components to be processed but above all for the safety of the operators.
The use of ergonomic arms for screwdrivers is functional to reduce the fatigue of the operator's hand-arm system because: they cancel the force in supporting the tool and the reaction on the operator's hand; they reduce the vibrations, they allow to maintain a good wrist position and the perpendicularity on the working point also improving the precision and the quality of the assembled product.
