MECHANISM CONVERTING SIMPLE ALL-TYPE HYDRAULIC ELEVATORS INTO HYDRAULIC ASCENDING ELEVATORS WITH USE OF A NEW-TYPE CONVERTER

摘要

Novelty: a mechanism converting simple all-type hydraulic elevators into hydraulic ascending elevators with use of a new-type converter (fig.1) is disclosed. Technical features: the invention (fig.1,4) is placed between the switchboard of the elevator (fig.1,1) and the operation motor (fig.1,6) and connected to the switchboard via the electric signals (fig.1,2), the electric connections R,S,T and the ground (fig.1,3); in the sequel, the invention is connected via the electric connections R,S,T and the ground (fig.1,5) to the operation motor of the elevator so that ordinary all-type hydraulic elevators can be converted into hydraulic ascending elevators with complete converter.
