A person in brown work boots operates a manual gray metallic tool to move gravel on a concrete surface.

Procedo con descrizione funzionale precisa e ridotta al minimo: quale parte fa cosa, in quale ordine di movimento, quali forze si trasferiscono e perché sposta il pietrisco. Nessuna spiegazione extra. Funzionamento in 6 punti operativi Posizionamento: lama anteriore sottile e inclinata (~15° rispetto al piano) viene infilata sotto il pietrisco, con la lama che tocca il piano di posa vicino alla traversa. Bloccaggio: operatore appoggia il piede sulla piastra battuta davanti alla lama; questo impedisce al telaio di scivolare in avanti e crea un punto di reazione rigido. Trasferimento di forza (leva): l’operatore abbassa il manico con movimento rotatorio attorno alla piastra battuta; il manico è la leva; il fulcro è la piastra/punto d’appoggio a terra. Azione della lama anteriore: abbassando il manico la lama scorre sotto il pietrisco e solleva leggermente il materiale verso l’alto/avanti (componente verticale + componente orizzontale della forza dovuta all’angolo della lama). Questo scollamento rompe la presa del pietrisco sulla traversa. Azione della lamina posteriore mobile: la biella collegata al manico causa la rotazione della lamina posteriore che si chiude verso la lama anteriore durante l’abbassamento; la lamina cattura il pietrisco sollevato e lo convoglia in avanti, impedendone la ricaduta indietro sulla traversa. Ritorno e riposizionamento: sollevando il manico la lamina posteriore si riapre (perno con molla o gravità) e la lama anteriore può rientrare più avanti per Ver mais
