Изобретение относится к транспорт-³ным средствам и, в частности к шасси транспортных средств для перевозки длинномерных грузов.The invention relates to vehicles ³ and, in particular, to the chassis of vehicles for the transport of long loads.

Наиболее близким к предлагаемому является транспортное средство для ⁵перевозки длинномерных грузов, содержащее раму, имеющую связанные поперечинами лонжероны и устройство для подъема перевозимого груза, включаю*^ щее приводные посредством силового цилиндра вертикальше штанги, несущие на нижних концах захваты (Д1.Closest to the proposed one is a vehicle for the transportation of long loads ⁵ , containing a frame having spars connected by cross members and a device for lifting the transported cargo, including drive axles vertical via the power cylinder, carrying grips at the lower ends (D1.

Однако оно не обладает достаточной надежностью и имеет значительный вес. Это вызвано тем, что механизм подъема выполнен в виде четырех отдельных вертикальных силовых цилиндров, каждый из которых снабжен синхронизатором их потока текучей среды, что _мприводит к значительному весу механизма подъема и всего шасси в целом· Соединение же каждого цилиндра при помощи отдельных шлангов с источником текучей среды под давлением не позволяет обеспечить достаточно высокой надежности.However, it does not have sufficient reliability and has significant weight. This is due to the fact that the lifting mechanism is configured as four separate vertical cylinders, each of which is provided with a synchronizer of fluid flow that _m leads to a significant weight lifting mechanism and the entire chassis generally · Compound same each cylinder through separate hoses to a source of fluid under pressure does not provide a sufficiently high reliability.

Направляющая выполнена с раструбом 22 и окном 23 для прохода рычагов 15 и 16 при их перемещении.A vehicle for transporting long loads contains a frame consisting of side members 1 connected by cross members 2, a cab 3 is installed on the frame, an engine (not shown), which drives the main gear 5 and the chain gear located in the casing of the wheel ~ 7 through the driveshaft 4. . The load lifting mechanism mounted on the frame consists of a horizontal power transverse cylinder 8, secured with a bracket 9 on the middle cross member 2 of the frame. The opposite ends of the rod 10 of the cylinder 8 are connected by means of a chain 11 to the sprockets 12. Each sprocket is fixed ··· fixed in the middle part of the shaft 13, longitudinally mounted in the cavity of the frame spar 1. The shaft 13 is mounted on the spar 1 using brackets. The ends of the shaft 13 are connected with the upper ends of the rods 14 using pairs of levers. The first lever 15 of the pair is rigidly fixed to the corresponding end of the shaft 13, and the second lever 16 is connected to the upper end of the rod 14 by means of a hinge 17.The free ends of the levers 15 and 16 are connected to each other by a hinge 18. The lower end of the rod is connected to the load gripper 19. A vertical guide 20 is fixed in the spar, in which the slider 21j is movably mounted fixed on the upper end of the rod 14.
