Impregnation tank for wood handling appliance - has pressure loaded units pressing wood up against buoyancy counteracting holder

摘要

Material is lowered into a basin by a fork on a hoisting appliance, and pressed against a downward holder to prevent it from floating upwards in appts. for impregnating timber. A pressure device with spring or weight-loaded pressure bars is mounted on the basin. This presses material upwards from below against a holder. It may be mounted on the fork with a parallel guide unit and the pressure element may be swivelling stirrup pieces. Large packages can be clamped, without risk of floating away, while less effort is required, and adaptation to timber quantity is improved.
