System with trolley and lifting device

Abstract

System (1) comprising a carriage (F) and a lifting device (H) for lifting the carriage (F), wherein the lifting device (H) comprises a base frame (6), a set of threaded drives (5), a lifting drive (54), and a coupling structure (55), wherein each threaded drive (5) of the set of threaded drives (5) comprises a threaded spindle (51) which is vertically oriented and fixed relative to the base frame (6), and a spindle nut (50) interacting with this threaded spindle (51) which is rotatably mounted about this threaded spindle (51) relative to the carriage (F), wherein the lifting drive (54) is configured to drive a drive movement of the coupling structure (55), wherein the spindle nuts (50) are coupled to the coupling structure (55) such that the drive movement of the coupling structure (55) produces mutually synchronous rotational movements of the spindle nuts (50) relative to the The carriage (F) around its respective threaded spindles (51) causes- wherein the set of threaded drives (5) is configured to convert the mutually synchronous rotary movements of the spindle nuts (50) into mutually synchronous vertical translational movements of the spindle nuts (50) relative to the base frame (6) along their respective threaded spindles (51),- wherein the carriage (F) is supported by means of the spindle nuts (50) in such a load-bearing manner that the carriage (F) follows the vertical translational movements of the spindle nuts (50) relative to the base frame (6).
