Abstract (en)
The present invention relates to a hoisting device for transporting objects, particularly goods, comprising: a cage member (3) in which the objects for transporting can be placed, which cage member is displaceable in a shaft (5); hoisting means (9) mounted on the cage member for hoisting and lowering the cage member in the shaft; electric drive means (7) connectable to a power supply for driving the hoisting means; the electric drive means comprising: one or more electric motors; one or more capacitors (13); switch means (12) for connecting the electric motors to the supply voltage when sufficient supply voltage is available, and connecting at least one of the electric motors to at least one of the capacitors when insufficient supply voltage is available, for the purpose of counteracting the downward movement of the cage member. <IMAGE>
