TWO-MEMBER CARRIER Russian patent published in 2000 - IPC

FIELD: transport engineering; timber industry. SUBSTANCE: invention relates to vehicles designed for collecting, loading or unloading and transportation of timber at felling areas. Proposed two- member carrier has front member I and rear member 2, hydraulic pump and hydraulic steering wheel coupled with steering cylinder, hydraulic manipulator 5 with turning hydraulic cylinders 6 coupled with hydraulic distributor controlled by electric joysticks. Each member is furnished with support for hydraulic manipulator. Two- position electrically-controlled hydraulic distributor is installed in hydraulic lines coupling hydraulic distributor with turning hydraulic cylinders. Hydraulic distributor is coupled with electric joysticks. Joysticks in neutral position provide flow of liquid in hydraulic distributor from high-pressure space into low- pressure space of hydraulic cylinders 6 when carrier is running. Two-position hydraulically-controlled hydraulic distributor is installed in pressure line of hydraulic pump. This hydraulic distributor is coupled with hydraulic distributor by pressure hydraulic line, and with hydraulic steering wheel, by pressure hydraulic line and control hydraulic line. EFFECT: improved efficiency and cross-country capability of carrier. 3 dwg
