ELEVATOR

摘要

The present invention pertains to the field of vertical transport techniques and more precisely relates to elevator structures such as lifts for displacing loads or persons upwards or downwards using mechanical devices fitted in said elevator. This elevator comprises a mobile frame with a drive, wherein said frame is mounted so as to be capable of displacement relative to a support guide having its support members connected to the driving gear of said drive. The mobile frame also includes rollers for fixing the position of the driving gear relative to the support members as well as support rollers coupled to the support surfaces of the support guide. The driving gear of the drive is mounted on a base together with at least two fixation rollers. The mobile frame further includes at least two support rollers, wherein all pairs of fixation and support rollers are rigidly mounted on planes which are parallel to one axis. The support members are made in the shape of inserts which are mounted so as to be capable of concentric rotation on rods attached to the support guide. The support members, the fixation and support rollers as well as the driving gear have their contact surfaces provided with an anti-frictional coating.
