Title:
ELEVATOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2003/008321
Kind Code:
A1
Abstract:
An elevator device so designed that when a car (1) tries to lift&sol lower beyond predetermined limits in a shaft (10), the pulley (5) of a hoist (4) slips with respect to a traction rope (3). This ensures that even if the car (1) tries to lift&sol lower beyond the predetermined limits in the shaft (10), such lifting&sol lowering beyond the predetermined limits is prevented, thus preventing such drawbacks as deformation and damage to the components (1, 3, 4, 8) of the device.
