FIELD: construction industry.
SUBSTANCE: lifting system consists of a cabin, roller device and load-carrying and/or rod and/or guiding element made in the form of a belt (30). Roller device includes two rollers (10,20) with rotation axes (12;22) that are parallel to some extent. Rollers (10,20) have structured peripheral surfaces with parallel ribs and grooves, and rotate towards each other when the cabin moves. Belt (30) retains the cabin from below. It passes directly from roller (10) to roller (20). Belt (30) has structured main surface (33) that corresponds to structures of rollers (10,20). Belt (30) spins around its longitudinal axis (32) in section (A) located between rollers (10,20) so that main surface (33) can be engaged with peripheral surfaces (13,23) of both rollers (10,20) when belt (30) wraps around rollers (10,20) that rotate towards each other.
EFFECT: invention provides the possibility of using one-sided shaped belt.
