<p>The roller track (1) conveys objects (T) by gravity and has track rollers (3) arranged in an inclined plane. A brake mechanism (6) comprises a brake bar (7) which extends parallel to the direction of the track and can be moved in vertical direction. The bar can be lifted above the tangent plane to the rollers by a lifting mechanism (8). The bar may be carried on a parallel, horizontally slidable element (11) having an inclined face supported on stationary rollers (16). The element may have rollers (19) supporting the bar (7).</p> |
