FIELD: machine building.
SUBSTANCE: invention relates to a lifting crane. When connecting together sections of the crane suspension assembly securing the frame to the element of the first section is attached a tension member between the frame and the connector used in the assembly suspension, move the tension member so that the connector is rotated about the pin to a position in which the second opening in the connector is aligned with hole in the element of the second section of the second pin passes through a hole in the connector through hole and the second section element and tension element is disconnected from the connector. Next, attach the frame to the collar to the suspension assembly section of the crane, the rope is attached to the connector on the gate, the gate is driven to move the connector, so that they may rotate about the axis of rotation, and fix the connector in its second position.
EFFECT: achieved is usability and ease of assembly and disassembly of the crane.
