LOADING EQUIPMENT Russian patent published in 1998 - IPC

FIELD: road-building machines, in particular, shovel front loaders. SUBSTANCE: loading equipment has base, boom and loader shovel. Plane extending through pivots for joining boom to base and for joining boom loader shovel is extending in parallel with straight line extending through pivots for joining hydraulic cylinder for rotating loader shovel in vertical longitudinal plane to base and to vertical tie-rods. Plane extending through pivots for attachment of longitudinal tie-rods to loader shovel and to vertical tie-rods is in parallel with mentioned plane and straight line. Distance between pivot joints for connecting boom to base and to loader shovel is equal to total distance between pivots for connecting hydraulic cylinder to base and to vertical tie-rods and between pivots for connecting longitudinal tie-rods to loader shovel and to vertical tie-rods. EFFECT: wider operational capabilities of loading equipment by providing planar-parallel motion of loader shovel and enhanced reliability in operation. 3 cl, 2 dwg
