The application possibilities are far ranging, this includes large parts as well as small parts, and especially applies to positions which are difficult to access The Annals of ''Dunarea de Jos'' University of Galati : Fascicle XIV MECHANICAL ENGINEERING, ISSN 1224 - 5615 2004-01-01T00:00:00Z http://arthra.ugal.ro/handle/20.500.14043/24500 Regarding the Efficiency of the Decelaration Through Impedance Coiling of the Hydraulic Cylinders Hauk, Niculai; Dumitrache, Petru The paper present a point of view sustained by calculations about the efficiency of the deceleration system by impedance coiling of the hydraulic cylinders. It is shown that the simple presentation of the impedance coiling system doesn’ t lead automatically to obtain an evident deceleration of the assembly piston-bar-moved mass. Added to the assembly of important factors which can be controlled and can induce the deceleration there is a number of random factors which have a significant influence.

Accepted practices in the precast industry are unique in some respects due to the industry's production environment. The following is a summary of some fundamental consolidation principles and recommended practices.

The work has as objective a these accomodation with the commands 3D the and a crossing from 2D to 3D how much the maul for everyone. The utilization commands 3D constitute a priority but no forgeted a commands of draw from 2D which constitute base of go on this modelling innards.
