Liftul propus include două elemente funcţionale - tambur cu motor electric şi organul flexibil. Viteza de ridicare-coborâre şi dirijarea mişcării se efectuează cu o singură mână a operatorului cu un efort de până la10 Newtoni. Raportul de transmisie a puterii depinde de numărul de înfăşurări ale cablului pe tambur. Greutatea de ridicare a încărcăturii depășește efortul asupra mânerului de zeci sau sute de ori. La elaborarea liftului propus sunt folosite formulele de calcul simple. Sistemul nu are nevoie de mult timp de pregătire.
The proposed lift includes only two functional elements - a drum with an electric motor and a fl exible member. The liftinglowering speed and motion control is performed with one hand of the operator with an eff ort of up to 10 Newton. The power transmission ratio depends mainly on the number of turns on the drum. And the weight of the lifted load exceeds the force on the handle tens and hundreds of times. Simple calculation formulas presented above are used in the elaboration of the proposed lift. The system does not need a long-term development.
