The got results allow to extend the application domain of conveyers due to creation of conveyers with changing length for the vertical and semi-steep portage. Application of drums with curvilinear formative allow to improve the indexes of the systems of the automatic centring of ribbon on a drum. At the increase of coefficient of bulge in 1,05 time permanent to time of adjusting (ribbon) object is increased on 2%, at the increase in 1,1 times on 5%, at the increase in 1,2 times on 9%. By comparison to cylindrical drums and flat ribbons, diminish application of drums and ribbons of concave type in two times of transitional area especially in tubular conveyers. Account of reologycal model of ribbon, modes of operations of conveyer will allow to estimate correctly strensth parameters at planning. In the work in detail the new method of development of durable soil by the scoop of clamshell is investigated with the use of central spiral anchor. Specified conformities to the immersion and work of spiral anchors of shallow position with of to 0,3 m and to 0,8 m allows to draw a conclusion that they can be used as fast repairing dismantled connections of clamshell excavations part with the array of soil. The expenses of time on setting of scoop and screwing into of anchor are within the limits of 5.10 cm., and bearing strength achieves 90 kV. The developed mathematical models of processes of introduction of clamshell in the array of soil allow to set the required effort of additional load taking into account construction of scoop and parameters of base machine. The method of choice of mass and distribution of masses base machine is offered taking into account durability of the developed soil. In theory grounded and experimentally confirmed possibility of the use of spiral anchors with different configuration of spiral blade providing the proper configuration of body of flow off. The set conformities allow to apply configurations of spiral blades taking into account construction of clamshell excavation part (2t, 4t or 6 jaws) and form of scoop (rectangular, spherical, trapezium type, etc.).
