Useful model relates down the woodworking industry, in particular, to the lumber works, and it can be used before the mobile cable skidding installations at the point of the development of cutting areas due to the conditions of hilly- growing reliefs. The technical task of useful model consists besides the improvement of the construction of rear mast, that ensure increase in the productivity of mobile cable skidding installation due to shortening of time down the installation of rear mast down it is operating the position and shortenings of time for re-basing of rear mast with the development of cutting area, especially with the development of the cutting area, located beyond the steep slope, and which also ensures reduction in labor expense and labor expenses of the process of development of cutting area due to its simplification. Rear mast for the mobile cable skidding installation is executed self-propelled by means of its arrangement with the possibility of lateral arrangement on self-propelled base 4, which has chassis 5 and drum 6 for rope 7, with this chassis of 5 self-propelled bases 4 it is supplied for the sake of turntable 8, and mast 1 is supplied for the sake of those connected with the aid of the hinge 9 vertical 10 and inclined 11 by counters; moreover latter 11 is fastened by means of pin 12 down turntable 8, and the rope of 7 drums 6 is reeved beside blocks 3 on upright strut 10. installation of rear mast during the work of mobile cable skidding installation down operating the position is achieved by turning of by hand turntable 8 with vertical 10 and inclined 11 by counters down to the necessary side. Then upright strut 10 by hand raises, in this case is selected the necessary length of rope 7 based on drum 6. after the development of the tape due to hinge 9 upright strut 10 plots down inclined counter 11 and by the turning of turntable 8 mast 1 is plotted before the transport position and rapidly they move beside another place, where the cycle is repeated. 2 p. of formula, 1 [nez]. p.
