<p>The forklift truck has a travelling chassis on which a mast moves at right angles to the travel direction. A load suppwith forks travels up and down the mast. Th prongs are formed by tubes (14, 15) telescoping together, one of them forming a ram, whose piston rod (17) is coupled to the other one for the extension and retraction movement. The rams can be hydraulic, while the outermost tube forms the load-supporting surface.</p> |
