Description

one

The invention relates to lifting transport machinery and can be used in the arrows of lifting machines.

According to the main author. St. No. 969641 is a known block cage of a small rifle crane, containing cheeks, between which a lifting body is fixed, and at least one unit, equipped with slats with stops fixed to the cheeks of the cage, and guides fixedly mounted on the head of a boom crane. interactions with slats and stops

However, when working with weights that are close in mass to the maximum capacity of the crane, the tip guides due to the deformation of the boom deviate from the vertical, which makes it difficult or impossible for them to enter the block band strands.

The purpose of the invention is to increase the ease of operation by maintaining the vertical position of the guides.

This goal is achieved by the fact that in the block holder of a jib lifting crane, an arrowhead head bearing the bearing direction is mounted on an axis that can be rotated in a vertical plane by means of a hydraulic cylinder, the body of which is rigidly fixed on the arrow, and the rod is equipped with a U-shaped clevis hinged to ogolovkom.

In the block holder of a boom load-lifting crane, the cap is mounted on the boom 1 by means of axis 2, and contains the pointer 3 about the inclinations directed from the vertical. Block holder 5 is made with an eye. The tip contains cheeks 6, pivotally connected using a U-shaped bracket 7 with a stem

After the load P has been grasped by the eye of the block 5, the guides 4 heads of the boom due to the deformation

The verticality of the guides is monitored using pointer 3.
