HYDRAULIC ENERGY-GENERATION ASCENDING AND DESCENDING ELEVATOR

摘要

Novelty: a power-generating ascending and descending elevator-inverter is disclosed. Constitution: for the descending elevator's course, a central panel is initially actuated and powered by the energy provider (fig.1.1) to first supply energy to the central converter and then -after necessary controls are carried out- to the converter AFE 2000; this converter supplies with dc energy the central INVERTER of the system for the start of the movement. In the descending movement and due to the inverse rotation and movement braking, the system consisted of the motor, the central INVERTER and theconverter AFE 2000 produces energy. Embodiment: the invention finds application in hydraulic elevators of any type.
