Universal crane booms works as follows.

Before you begin bulldozer blade 11 is in position I, the lifting lever 9 with the counterweight 25 is omitted (see Fig. 1). Turns on the winch 7 and begins to choose a cargo rope 8, which moves the supplemental frame 15 with the bulldozer blade 11 along the guide 12 in position II. While moving the additional frame 15 at the same time dilatory cable 23 lifting lever 9 is pulled through the variable geometry mechanism 24 for additional support rack 21. When moving the bulldozer blade 11 from position I to position II fence is ground at a distance of 7-8 m and forming the front of the bulldozer prism of soil". In the end position II bulldozer blade 11 by a hydraulic cylinder 6 is the rise of the arrows 3 angle 10-14aboutwith the formation of the "prism of soil" height 1-1,2 m then odlucim cable 23 moving the bulldozer blade 11 to the initial position I. This movement is facilitated by the position of the boom 3 is already specified angle 10-14aboutthat leads you turn off the winch 7 to pilling additional frame 15 with the bulldozer blade 11 along the guide 12 to the original position II. After the return of the bulldozer blade 11 in its initial position II by the hydraulic cylinder 6 is lowered by the arrow 3, and then can be new soil samples.

If necessary, the sideboom crane can work on zacapu pipes without removing the guide 12 additional frame 15 with the bulldozer blade 11. When the excavation crane hook with a cargo rope 8 is not removed, additional frame dozer blade connects to the crane hook intermediate cable. Before carrying out lifting operations intermediate cable is disconnected, freeing the crane hook, and dozer is now in its original position I. during this crane booms on the construction of dams embankment maps for reclamation due to the lack of stress on the suspension when moving soil dozer blade, driven cargo winch, the wear of the suspension is reduced, which leads to the prolongation of the service life of the crane-truboukladchik is romanization surface mining.
