FIELD: transport.
SUBSTANCE: lifting system includes hoist box. Multiple belts are located relative to the hoist box so that their displacement to produce the hoist box movement should be approximately equal to quadruple value of corresponding hoist box displacement. The first, the second, the third and the fourth pulleys are supported with possibility of vertical displacement with hoist box and rotary traverse relative to the hoist box. Each belt has a portion passing through the hoist box between the first and the second pulleys and vertically aligned with other portion of the same belt passing through the hoist box between the third and the fourth pulleys, as well as has at least some vertical overlapping with other portion of the same belt passing through the hoist box between the third and the fourth pulleys.
EFFECT: reduced space occupied.
