FIELD: mechanical engineering.
SUBSTANCE: folding hinged lift of suspended load contains a support base and a hinged load suspension kinematically interconnected by means of a drive closed kinematic chain. The chain is made in the form of identical hinged rhombuses sequentially arranged in the same plane and interconnected. Rhombuses are made up of intersecting and identical three-hinged connecting levers. Hinges of levers are located on the same straight line. The rhombus located at one end of the chain is kinematically connected to the support base, and at the other end is connected to a hinged suspension by means of two identical double-hinged levers. The length of double- hinged levers is equal to half the length of three-hinged levers.
EFFECT: simplification of the design, increase in the height of lifting the load, as well as compactness of the lift in its non-working position is achieved.
