RESEARCH OF WORKING EQUIPMENTOF BULLDOZERS FOR SORTING OUT OF OBSTRUCTIONS ON ROADS
Problem statement. Technogenic catastrophes, failures or natural calamities, lead to destruction of buildings and buildings and transport ways. In the presence of intact motorways, there are wreckages of destructed buildings which form obstructions and hinder motion of technique and workers to the object of implementation of works. Sorting out of obstructions is done with machines and mechanisms which do not meet the requirements of these works, that predetermines implementation of rescue or restoration works on imperfect technological charts, especially on the initial stages, and it increases terms and labor intensiveness of their implementation. Development of new types of machines and their working equipment is therefore needed with the grounded parameters for the effective sorting out of obstructions on transport ways. Purpose. Development and research of working equipment of bulldozers for sorting out of obstructions of the blasted buildings and buildings on roads. Conclusion. The construction of working equipment of bulldozers is developed for sorting out of obstructions of the blasted buildings as captures which are set on a dump, and the rational parameters of new type of equipment are determened. As a result of researches efficiency of bulldozers is set with captures. Specific indexes of work of bulldozers with captures in 1,8…2,0 times are higher, than at the bulldozers of traditional construction. The tests of experimental standard of bulldozer of DZ-162 with the captures of production of Berdyansk plant of road machines confirmed its capacity, efficiency and prospect of the use for liquidation of extraordinary events.
