Description

The invention relates to lifting equipment, namely to cranes mounted on vehicles. According to the main author. St. No. 225395 is known for a load-lifting crane containing a suspension part, variable luffing jib, which is connected by means of a hinged frame to a support stand, which is supported on the ground by means of shoes and is connected at the base by a hinge to a turntable of the crane. Its disadvantage is the impossibility of rotation of the crane under load and low mobility of rotation without load. The aim of the invention is to improve the maneuverability of the crane. The goal is achieved by the fact that the crane is equipped with a curvilinear guide connected by hinge rods to the undercarriage with it, the shoes of the support bar are mounted on the said guide. FIG. 1 shows a front view crane; in fig. 2 - the same in the transport position; on fng. 3 is the same, top view. The truck-mounted crane contains two support posts 1, on the KOTOpiiie is a strut 2, pivotally attached to the uprights and the boom 3 mounted on the rotary plate 4) the form 4 of the crane. On the strut hung by means of a polyspast 5 hook holder 6. With a turntable platform, the pillars are connected by means of g-drivers 7 by means of hinges 8 and 9. Between them, the buckles are fastened with a strut 1O. The crane's fastener supports tackle 11. The legs of the stand rest on the shoes 12, which can be performed on any X ode. I will move the shoes on an axial 13 or a planned area, rounded with the required radius of the rim, on the support post around the center of rotation of the rotary weeping of the crane.

The guide is connected to the running frame 14 of the crane with the help of shnnirny t g 1 5.

The riorf.bevf rack and the OcyFiiec guide is equipped with a 1 6 BCIK mechanism for lifting cranes.

The proposed load-lifting crane works as follows.

A self-propelled Crane enters a prepared platform in the tianto ftopraoM position and lowers a guide 13 with racks onto the supporting surface with the help of auxiliary lift mechanism 16. During the rotation of the plates (|) of the form 4 of the crane, by means of the tons of gn 7, they move along the guide post with the shoes 12 by the required angle relative to

54 run ram depending on the location of the lifted load. The downstairs, 6, moor a lifted load. The Herata turntable, together with the support post, carries the raised load to its installation site.
