SUBSTANCE: invention relates to lifting and transport mechanisms and is designed to perform work at height in the production of repair, construction and other works, as well as for the maintenance of buildings, structures and devices of urban utilities. Lift contains support frame (1) placed on a mechanized chassis with a pair of front and rear wheels (2, 3) on support surface (4). Boom (5) of pantograph type with hydraulic cylinders (6, 7) and articulated paired sections (8) with a vertical working stroke is mounted on support frame (1). Working platform (9) with protective barriers (10), made with sliding section (11), is mounted on the upper section. Tipping protection device is inserted in the device, which includes static stops (13, 14) for each wheel in the form of a metal sheet rigidly fixed on the basis of the supporting frame on the inner side of the pairs of front and rear wheels (2, 3) at a certain distance from them with rounding of the corresponding wheel and strengthening with metal lining (15). Symmetrical service stops (16) in the form of a pair of metal plates are fixed with the possibility of rotation from opposite sides on the central axis of the second pair from the bottom of articulated paired sections (8), the ends of the plates are provided with recesses for connecting articulated sections (8) with working platform (9) raised.

EFFECT: lift ensures reliable and safe operation and maintenance.
