MULTIPURPOSE DOZER EXCAVATOR Russian patent published in 2013 - IPC E02F3/04 

FIELD: transport.

SUBSTANCE: proposed dozer comprises control assembly with adjustment pumping unit communicated via pipelines with hydraulic assemblies, tanks for fuels and lubricants and working fluid, platform, bearing turntable, rotary barrel (with check vale, not shown), two-way hydraulic cylinder, rams with tables, fluid operated telescopic boom articulated with aforesaid platform and drive. Extra turntable is arranged at boom end and connected with aforesaid drive. Extra turntable is compatible with attached implements. Lifting mechanisms with supports are secured in lugs of two-way cylinder secured at bearing table. Speed of displacement of dozer and excavator implements makes 0.5 m/s or 1800 m/h. Efficiency of dozer is two times as high owing to operation without idling, displacement of soil with loading and using piling according to trench profile. Fuel and lubricant savings are ensured result from traction forced higher than 35^th class due to using appropriate power cylinders. Multifunction operation, new soil excavation processes, higher efficiency, savings of fuels and lubricants and lower metal input.

EFFECT: multifunction operation, new soil excavation processes, higher efficiency, savings of fuels and lubricants and lower metal input.
