20 and bend on both sides along a radius of 0.6 m.

Deserves attention and can also be used on industrial construction of a portal-tractor traveler.

Portal-tractor traveling is usually performed by the construction organization itself. The traveler consists of two gloza with a superstructure made of rectangular frames, interconnected by two upper longitudinal beams and slants. The width of the traveling ladder in an external outline is taken 3.32 m from the calculation of entering it to the dimensions of the rolling stock; The internal size between the racks is adopted 3 m (the length of the sleepers — 2.7 m and a supply of 0.3 m) to serve the traveler loaded under the portal of the trail -loaded tracks of carts. The height of the crane above the runners from the inside 3 m provides the supply of the TsNII trolley under the crossbar of the traveling rod, loaded with five collected links. The traveler’s crossbars are connected to the racks on the bolts, which allows you to disassemble and move it. The length of the traveler is 6-6.5 m, the runners are made of a channel No. 20 and bend on both sides along a radius of 0.6 m.
