TRUCK LOADER (VERSIONS) Russian patent published in 2006 - IPC E02F3/34 

FIELD: transport engineering; wheeled loaders.

SUBSTANCE: invention is aimed at creating truck loader in which mounted implement or appliance can be turned, when necessary, when lifting frame is raised, by applying high torque, from position in which said implement or appliance in tilted downwards into position in which it is tilted upwards, without considerable reinforcement of tipping cylinder. For this purpose lifting frame of truck loader has Z-like kinematic motion provided by auxiliary lever with lifting cylinder connected with frame of said wheeled vehicle or with front part of truck loader, and reversible rocking lever connected with auxiliary lever, tipping cylinder and connecting tie-rod designed for turning corresponding mounted implement or appliance being connected to ends of reversible lever. Said mounted implement or appliances, for instance, bucket or log loader, are made to provide their fastening on lifting frame. To provide possibility of turning of corresponding mounted implement or appliance, when lifting frame is in lifted position by applying high torque required for turning from position in which said implement or appliance is tilted downwards to position in which it is tilted up without considerable reinforcement of tipping cylinder, at least one hydraulic cylinder is connected to lifting frame in direction of said mounted implement or appliance in front of higher joint connecting tipping cylinder with frame of said wheeled vehicle. Piston rod of said cylinder, being fitted for free travel, interacts with turnable axle connecting reversible lever with tipping cylinder.

EFFECT: enlarged operating capabilities.
